Possible To Use ReportViewer To Change Connection Strings Of A Report's Datasources?

Nov 9, 2007

Is it possible to use a ReportViewer control (or something in .net) to change connection strings of a report's datasources?
The connection string comes from a shared data source, so using an expression for the connection string in the actual report is out.


Essentially, I'm looking to tack on Analysis Services cube role(s) to the connection string to change data permissions. If there's another way to do this with a RS report, I'm all ears.

Change Query Of Report In Reportviewer

May 8, 2007

Hi,



I have a reporting services report that i show in an asp.net page by a reportviewer control.

Is there a property that i can set in my asp.net page, to change the query for changing the data in my report.

The number and names of the columns will be the same.



I should work with parameters, but the query changes more than just a few where-clauses. So i think working with parameters looks impossible.





Thanks,

Dennis

Dynamic Report With Several Datasources

Feb 15, 2007

Hello,

I am currently working with SQL 2005 Reporting Services and MS Visual studio 2005.

In my SQL server I have data about organizations, so that each organization's data is stored in an individual database.
In addition, the number of organizations/databases is variable. I know the number of organizations and the name of each one (that it agrees with the name of its database)
because there is a database (organizationsDB) with a table (organizationsTB) containing the list of the organizations.

So, It would be possible to create a report containing a summary of each organization? .... for example a table in which each row contains data of each organization.

Could you give me any ideas?

Thanks in advance!

SSRS Report Deployment And Shared Datasources

Mar 12, 2008

Hi,

I have got a quistion in regards to SQL Server Reporting Services 2005. We're currently using the SSRS in one of our applciations with 20+ reports. We need to deplaoy 2 instances of an applciation: Test and Production. These applcaitions are running off two different databases in SQL Server [DBName]_Test and [DBName]_Live. So far all of our reports have been written to use a shared datasource. This worked fine untill we had to deploy a Live instance of the application, where the shared datasource is overwritten with the live one.

Now we have manually created a new shared datasource called [DataSource]_Live. However, whenever we need to redeploy the reports from visual studio, we then have to go though each report and point it to a correct datasource. This is extremly manual process - and takes up a lot of time...

Surely there must be an easier way around this (without duplicating the reporting project in VS.NET / or having to modify the datasource fr each report manually each time)?

Thanks in advance,
Nick Goloborodko

ReportViewer (web Control) - Parameter Change Refresh

May 13, 2007

I have created an ASP.NET website with a ReportViewer on. The report renders fine, but when I change one of the parameters (manually), the report seems to invalidate itself and a blank while area is drawn. I would like the same behaviour as in the WinForms variant, where rhe rendered report remains the same until the 'View Report' button is pressed.



Is this possible?

Connection Strings, Trusted-connection VS Username-password, SQL Server 2005 Express

Mar 9, 2007

All --
Please help.
I have some questions about connection strings.
 
BACKGROUND...

Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
 
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
 
Please advise.
Thank you.

Does SP1 Change The Way Strings Or Data Are Processed?

Nov 1, 2006

We've just patched our Dev server, and, of our 3 servers (Dev, Test, Prod), we see major changes in the output of a raw data import process that runs nightly. Each night we import tables from a Remedy helpdesk system running on Oracle and place each ticket into a row on a table, tracking the changes and history of the ticket, etc. This includes tracking when supervisor groups are changed during the course of a ticket (ie Helpdesk to Data Comms to Billing etc). Now, after SP1, the results on Dev are skewed with partial strings showing in the From and To fields, broken in odd places (like the middle of words).

Has anyone noticed any changes in which post-SP1 SQL Server 2005 processes strings? Does it automatically trim spaces or convert NULLs etc?

The data import should be identical between Dev and the other servers.

ReportViewer Not Correctly Rendering Report

Aug 20, 2007

Hi,

I have a report viewer control within a web user control which i am using to display the report. The report has been designed within a Visual Studio Report Server project and it looks fine when previewed here but when i deploy the report to the reporting server the table rows within my report become stretched and there are other formatting issues, the formatting issues occur when the report is viewed from both reporting services server and my webpage. When the report is exported to a pdf from my website it looks fine why is the report not rendering correctly.

Has anyone else had this issue?

NOTE: I am using IE7

Probleam With ReportViewer Jumping To Report

Jan 10, 2007

Hi,

We have an ASP.NET application using a ReportViewer to show reports. I have two reports (both with logo - image - in yours headers):

- Report A: with action to jump to Report B.

- Report B: with action to jump to Report A.

This work fine into BID and into Report Manager, but into our application, when I click in first link into Report A, show me the Report B, but our logo isn't visible. If I try to return to Report B (clicking in action), show me this error:

The path of the item "(null)" is not valid. The path must be less than 260 characters long and must start with slash. Other restrictions apply. (rsInvalidItemPath)

May I need to configure something into my web.config to work fine too?

Thanks.

Connection Strings

Nov 24, 2007

I developed an application and deployed it onto a hosted provider.  I use SQL 2005 Express for development SQL 2000 for production.  Both systems work.
I backed up my production database and wish to use it for my development testing.  I restored it as a SQL 2000 database on my development machine and changed my connection strings to point to it.  I added it as a new Data Connection in Database Explorer and can see all of the data through it, but I see that all the tables now have the owner name in parenthesis as part of the table name.
My application now fails trying to find any of the tables.  It works if I include the owner name as part of the SELECT statement.  So much for data separation.
I don't know where to start.  Is this an issue between SQL 2005 Express and SQL 2000, or is it an issue between SQL and ASP.NET, or is it a hosting provider issue, or what?????

Connection Strings

Jan 24, 2008

Hey guys, don't know if this is in the right place but here goes.
I'd like some advice on optimizing the way I write my code. Here's the scenario. I have a select string for 3 different tables. One for the main gridview, and two others that are binded to dropdownlists.
So I created a Sqldatasource1,2,3 and had to create the connection strings for each one.
ex. SqlDataSource1.ConnectionString = "blah", SqlDataSource2.ConnectionString = "blah", SqlDataSource3.ConnectionString = "blah"the thing is, the connection string itself is the same. Is there a way to consolidate that? So that when I use a select/update/insert command for each sqldatasource i dont have to have another connection string? Also, having multiple connectionstrings, does that slow down the performance?

Connection Strings

Nov 6, 2006

I have created a SSIS package, and got it to perform as I want.

I am having a problem though with connecting to my data source (OLE DB Source) using SQL Server Authentication.

If I use Integrated security, I have no problems. If I use SQL Server Authentication, I get errors.

Here is the connection string that works:

Provider=SQLNCLI.1;Data Source=.SqlExpress;Integrated Security=SSPI;Initial Catalog=MyDataBase

Here is the connection string that fails:

Provider=SQLNCLI.1;Data Source=.SqlExpress;Persist Security Info=True;Password=**********;User ID=myUserid;Initial Catalog=MyDataBase

The strange thing is that when I use the Connection Manager dialog screen and click on "Test Connection", I get the response that the connection succeeded. It is only when I try to run the task that I get an error.

Here is the error I am getting:

[OLE DB Source [1]] Error: The AcquireConnection method call to the connection manager "MyDataBase" failed with error code 0xC0202009.

[DTS.Pipeline] Error: component "MyDataBase" (1) failed validation and returned error code 0xC020801C.

I have eliminated the obvious errors (incorrect Userid or password). Also, I am unable to use Integrated Security as this package needs to be distributed to various systems that may or may not be on our company's primary domain.

It seems I am missing something really basic here, but am not seeing it.

Any thoughts?

Open Reporting Services Report Using ReportViewer

Aug 27, 2007

I tried to open a SQL Server 2005 Reporting Service report in ASP.Net 2.0 using ReportViewer. The following is my code.


Dim param(2) As Microsoft.Reporting.WebForms.ReportParameter
param(0) = New Microsoft.Reporting.WebForms.ReportParameter("ProjectID", Me.cboProject.SelectedValue)
param(1) = New Microsoft.Reporting.WebForms.ReportParameter("RunBy", Session("strEmployeeName"))
Me.ReportViewer1.ServerReport.SetParameters(param)

Me.ReportViewer1.ServerReport.ReportServerCredentials = New _
clsReportServerCredential(System.Configuration.ConfigurationManager.AppSettings("strReportViewUser"), _
System.Configuration.ConfigurationManager.AppSettings("strReportViewPassword")

Me.ReportViewer1.ServerReport.ReportServerUrl = New Uri(http://SQL2005/ReportServer/)
Me.ReportViewer1.ServerReport.ReportPath = "/nsPortalReports/rptIssuesByRole"
Me.ReportViewer1.ServerReport.Refresh()


I need help with passing multiple parameters. I got an erron on the second parameter (parm(1)). The error was

"Overload resolution failed because no accessible 'New' can be called without a narrowing conversion:
'Public Sub New(name As String, values() As String)': Argument matching parameter 'values' narrows from 'Object' to '1-dimensional array of String'.

How can I pass the parameters?

Help! Jump To Report: Error With Web Reportviewer Control

Jan 14, 2008

Hello everyone,
I have a report that has a "Jump to report:" link in it and in the report it jumps to there is another "Jump to report:" link. When I click on this link I get the following error.

The path of the item '(null)' is not valid. The full path must be less than 260 characters long; other restrictions apply. If the report server is in native mode, the path must start with slash. (rsInvalidItemPath)


I have tried moving the link from the header to the body of the report with the same results.

This is only happening in the web reportviewer control as our windows app works flawlessly.

We are running SQL SERVER 2005 SP2.


Does anyone have a fix, workaround or idea how to resolve this issue?

Thanks in advance

ReportViewer Does Not Show Report In Aspx Page

Jul 13, 2007

I created a report with a parameter. The parameter was created using a dataset in the report designer. This works fine. I deployed the report (webhost4life) and the report runs fine in the report manager. I am able to select my casenumber click on the default view report button and it works.

Problem: I embedd the report into an aspx page frmReports1.aspx. I call this page from another page (form). the frmReports.aspx page comes up and displays the default drop down list box with the casenumbers (fine). I select the casenumber and click on the view report button and NOTHING. I here the postbacks taking place but all that happens is the default value appears in the drop down list box and the toolbar shows. I checked permissions and everything is fine. I searched the forum and thought i found the solution with the inLine HTML and Async (still nothing) I can only think that something is not going right with the parameter. Here is my html, and code behind code. any help would be greatly apprcieated.

Dynamic Connection Strings

Feb 5, 2007

Hi,
I am looking to allow a user to select which database they need to connect to, and then for them to be able to use that connection string until they choose a different database. I have a separate database specifically to hold the list of databases with the respective connection strings, and various forms that are currently looking at the web.config for the connection string. Unfortunately, I can't just put all the connection strings into the web.config as the number of databases available to the user will increase on a weekly basis which will be handled by a database administrator, so I want a user to select from a list of databases (for which they have permissions), and for that connection string to remain for that user. Potentially there will be 20 or more users each connected to a different database (all SQL Express).
If anyone can provide any help on this I will be truly thankful as I've hunted on the internet for hours and have been unable to find anything that has helped.
Thanks in advance.
Paul

Dynamic Connection Strings

Feb 6, 2007

Dynamic connection strings
I have found lots of people asking for something similar to this but cannot find any solutions - can you help?
I am developing an application (ASP.Net2) in which users are associated with 'Clients' and every Client has their own SQL Server database.
Users are authenticated using standard ASP.Net Authentication via a separate database (common for all users). This includes a table linking them to a Client and each Client record includes the connection string to their database. Currently a default connection string is held in the web.config file.
My problem is that I don't know how to dynamically change the connection string after a user has logged on. I have a large number of databound controls, many of which are declared and some are coded in the VB.Net code behind. I know I can use code behind to change the connection string for a SQLDatatSource:
I thought I had it cracked with the following:
Public objClientConnection As New ConnectionStringSettings
Public Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)If Session("ClientDBConnectionString") <> "" ThenobjClientConnection.ConnectionString = Session("ClientDBConnectionString")objClientConnection.Name = "ClientDBConnection"objClientConnection.ProviderName = "System.Data.SqlClient"ElseobjClientConnection = ConfigurationManager.ConnectionStrings("WebTool1ConnectionString")End IfEnd Sub
The session variable Session("ClientDBConnectionString") holds the client specific connection string and is populated when the user logs on. If this is not populated then the connection string defaults to one collected from web.config. This should ensure there is always a design time connection string available.
The trouble is, when I try and declare the SQL data souce like this:
<asp:SqlDataSource ID="dsTest" runat="server" ConnectionString="<%# objClientConnection.ConnectionString %>" SelectCommand="usp_SEL_DocumentTypes" SelectCommandType="StoredProcedure" ></asp:SqlDataSource>
I get an error: The ConnectionString property has not been initialized.
I have been going around in circles on this for days and would really appreciate some help. Am I on the right lines? What needs to change to make it work? Is there a better way?
Many thanks,
Cliff

TableAdapter And Connection Strings

SQL Server Connection Strings

Dec 18, 2003

I should start by saying that I'm new to SQL Server and ASP.NET. My question is about connection strings. With so many possibilities of these strings, how will I ever know what is best to use or try when one does not work. Is there a rule of thumb or an article or even a book that someone can recommend? Something that will demystify this part of working with the SQL Server and ASP.NET?

Thank you very much for any help on this.

AS400 DB2 Connection Strings

Jan 17, 2007

I am trying to construct a connection string via iSeries OleDb provider. The default list of libraries on the AS400 for my user is fine for production. But in test scenarios the code/data libraries are rolled out through a sequence of test libraries. How do I specify the additional libraries for testing.

I connect fine and can execute sql. the statements like insert into TestLibrary.Table work fine, but the associated trigger code isn't called.

Would it be better to use the .Net Connection set of classes instead. I switched from ODBC to OleDb because of assumed thread safety issues.

Reporting Services ReportViewer Page Is Not Displaying The Report

Aug 14, 2007

Hi

I had a problem accessing our report manager via the web front...
We deleted the virtual directories in IIS and then recreated them... this required us to make a change in the rsWebApplication.config file to include the URL in the ReportServerUrl tag before we could access the site again.
Now we have access to the site but when we attempt to view a report that we deployed to it - the report fails to render and returns a rsReportNotReady error, even though the report doesnt use a snapshot.

Furthermore, the strange thing is that the filters for the report don't display in their own collapsable bar as they used to before... they just display on the white part of the page. Neither does the reportviewer toolbar display properly. It appears as labels and textboxes going down the page and not in a toolbar as you might expect...

any help is appreciated... we suspect that it is some kind of configuration issue, but we have no clue where to begin...

Question Regarding SQL Express And Connection Strings

Nov 20, 2007

Hello everyone! I am having some more problems while trying to get my site online. I built the site offline using Visual Web Developer Express Edition, and used "SQL Server Express" that comes with ASP.Net.  Therefore, I have the ASPNETDB.mdf and mydatabase.mdf in the App_Data folder.  Now, on my local machine everything runs fine.  When I tried to put the site online however, I get the following error:An error has occurred while establishing a connection to
the server.  When connecting to SQL Server 2005, this failure may be
caused by the fact that under the default settings SQL Server does not
allow remote connections. (provider: SQL Network Interfaces, error: 26
- Error Locating Server/Instance Specified) This is the connection string in my web.config file:    <connectionStrings>        <add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|mydatabase.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>    </connectionStrings> Now, my web-host does have SQL Server 2005.  Does my ASP.Net application use that though, since I have it running just through SQL EXPRESS?  Also, does anyone know where I could change my "SQL Server 2005" settings?  My web-host uses Plesk 8.2.0, and the database managing program is "ASP.Net Enterprise Manager", but I can't find any options anywhere to change the Server settings to allow remote connections. Any help would be greatly appreciated!  Thanks in advance, Markuu
