View 5 RepliesI'm trying to assign a datasource to a gmap control in 2.0 so that i can get pushpins in the map for all the locations in the sql db. I've enclosed my code below as well as a link to the site that provides the control and their sample. Can anyone tell me why it won't show the pins? What am I doing wrong?
Thanks.
My Code (sqllocations is a datasource):
GMap1.DataSource = sqllocations;
GMap1.DataBind();
Their site: http://en.googlemaps.subgurim.net/ejemplos/ejemplo_991000_DataSource.aspx
Their example (part of their explanation is not english, sorry):
List<DataSourceField> fields = new List<DataSourceField>(); fields.Add(new DataSourceField(45, 2, "hola"));fields.Add(new DataSourceField(46, 3));// Lo comentamos porque al utilizar la clase DataSourceField, // pero si fuera un dataset o cualquier otra cosa, // le deberíamos dar los nombres correspondientes// GMap1.DataLatField = "lat";// GMap1.DataLngField = "lng";// GMap1.DataGInfoWindowTextField = "gInfoWindowText";GMap1.DataSource = fields;GMap1.DataBind();
Hello,
I encountered an interesting situation. I have a gridview and a sqldatasource. It has delete function. When I delete a record an error of foreign key violation is raised. I would like to trap this error and give a user friendly message to the user.
If I use ADO.Net I can use Try/Catch, but it seems there is no way to do the same thing using datasource. Anyone knows?
Thank you,

Hi all,
Can anyone tell me how I can do a "Dirty Read" on a SqlDataSource Control? I'm affraid that the record locks are causing problems on the live system.
It is connected to an infromix db using odbc. Thanks.
Hey all,
I was wondering what the best method of checking on page_load if a datasource control is pulling back nothing from a database. I want to display a message explaining that there is no data to be displayed. How would I go about doing that? I have tried searching google and whatnot but didn't find anything really helpful.
Here is the current code for the data source control.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|EventInsider.mdf;Integrated Security=True;User Instance=True"
ProviderName="System.Data.SqlClient" SelectCommand="SELECT Events_Groups.GroupName, Events_Groups.GroupID FROM Events_GroupMembership INNER JOIN Events_Groups ON Events_GroupMembership.GroupID = Events_Groups.GroupID WHERE (Events_GroupMembership.UserID = @UserID)">
<SelectParameters>
<asp:SessionParameter Name="UserID" SessionField="UserID" />
</SelectParameters>
</asp:SqlDataSource>
But I have no idea what the code behind would be to check it on page_load. If there is no way to particularly do this, do you have to do it per control? Like dropdownbox's or gridviews? I am just confused on how to check to make sure there is data to be displayed.
Thanks,
Chris
does anybody know where I can learn how to add, update, delete using SQL datasource control? I have a couple of books that shows me how to SELECT but nothing shows me how to update, add new record or delete with the SQL data source control. Even this website doesn't have any tutorial. Does any body know where I can read up on how to use all features of this control? Or where that have a couple of examples on how to use it?
View 5 Replies View RelatedHi I am trying to open a database connection to a Northwind database. I can open it with a datasource control and return data to a gridview, but can't programically. I get a sqlexception error. this is ust for learning.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim S As New SqlConnection Dim builder As New SqlConnectionStringBuilder builder("Data Source") = ".SQLEXPRESS;AttachDbFilename=C:SQLNORTHWND.MDF" builder("Integrated Security") = True builder("Connect Timeout") = 30 builder("User Instance") = True S.ConnectionString = builder.ConnectionString Me.Label1.Text = S.ConnectionString S.Open() Me.Label2.Text = S.State.ToString S.Close() Me.Label3.Text = Me.SqlDataSource1.ConnectionString.ToString End Sub
The text in label2 and Label three are identical except there are "" around the datasource.
How come I can connect through the datasource control but not through code?
I can select the tables and fields, but when I click on Advanced the Check Box to Create the Commands is not available. they are dimmed out.
Why is this happening, is it a setting that I have missed. Any help is appreciated.
I am trying to create a MS Access datasource to use it in a IS dataflow. I've done the following things:
1.I've created an ODBC datasource - System DSN, pointing to the Access database.
2.I've created an ODBC connection manager pointing to the ODBS datasource that I created in the previous step.
3.I've created a DataReader Source that uses as its Connection Manager the connection manager that I created in the previous step.
I get the following error message: "Cannot acquire a managed connection from the run-time connection manager." What can I do to solve this error?

Hi all,
Please advise which kind of connection should be establish from excel 95 to MS SQL Server.
From my thought, I understand that the connection depends on Windows version rather than excel version.
Thus, I just think that there will not be any issue connecting to SQL Server from Excel 5.0a.
Kindly advise if there is any addtional point to concern/consider further.
What could be issue connecting to SQL Server 2005 from Excel 5.0a.

When creating a user control (ascx) and registering it in the webpage, an error occurred:
"Login failed for user ''. The user is not associated with a trusted SQL Server connection."
This error does not appear when creating data access normally, and I don't use username/password for the northwind database; any suggestions.
I have a combo box named [myControl] on an Access form that I can use to select/enter a site name (ABC). There is a button on the same form that runs a report. The underlying record source for the report is a SQL Function. Is there an easy way to pass the combo box value to the SQL Function so that only records for site 'ABC' are displayed in the report? I tried Forms![myForm]![myControl] in the criteria box of the Function and it did not work. THANKS!

I am just wondering if i can control the access of range of variables from users' logins.
To be more specific, if i a parameter alpha has five values (1,2,3,4,5) and then i have 3 users A, B C, what i need is:
1. A can access Vaues(1, 3)
2. B can access Values (2, 4)
3. C can access Values(3,5)
Is there anyway i can do this either from the stored procedure i am getting the data or i can do it on SSIS development side?
Hello,
I have a database (SQL 2005) with two schemas (dbo and s1) and with tables defined in dbo and tables defined in s1. The stored procedures are also defined in both schemas, some of them in dbo some of them in s1. Some of the stored procedures query tables from dbo and s1 at the same time.
I want to have a new db role with access to the database only through sps and no other access read/write to the tables. I created a new db role and granted execute permission to it and assigned a user to it.
When I execute stored procedure defined in dbo with query against dbo tables, it works as expected.
However, if I run stored procedure defined in s1 with query to table in dbo, I receive error about missing select permission for the table in dbo. I am not sure why, but I can assume there is an issue with the ownership chain.
I can grand read/write permission for the tables, but this will break our original requirement for limited access to the db only through sp.
The other option is to have another role r2, with read/write, privilege and to use EXECUTE AS r2 in the sp.
I would like to ask first why the error for missing select permission happens and is there another way to have role restricted to only execute permission for all stored procedures.
Thanks,
IT
Hi every experts

UPDATE #2: When it said "Do you want to install Microsoft SQL Server" I said "yes" and that caused it to work. I exited and re-ran and now the print runs w/o the "install SQL Server" (If the prompt had said "Do you want to install the print dialog" we wouldn't be having this discussion...)
UPDATE: After posting this i discovered that the same thing occurs when attempting to print the report direct from IE6: First a dialog pops up "Do you want to install this software?" Name: Microsoft SQL Server. When I click "Don't Install" I get the dialog "unable to load client print control." Since this happens direct from IE6 I suspect it's browser settings. I'll resume tomorrow and post a followup.
My WinForm C# app integrates Reporting Services by calling them from WebBrowser controls. The problem is attempts to print cause a dialog: "unable to load client print control."
I've read prior posts that say "enable Active-X in your browser" - I don't know how to do that from a WebBrowser control.
Any ideas how to support Reporting Services "Print" from within a WebBrowser control?

I working on a form using an SQL DataSource. I am going to add a where clause. In that where clause a value from a label will be passed from the user.
How do I pass to the HTML Source the label value from the where clause. The value can change from user to user.
Sample below:
SELECT [KeyRolesID], [KeyRolesDesc] FROM [KeyRoles] WHERE ([JobCodeFamily] = @JobCodeFamily).
I want to replace the @JobCodeFamily which is currently coded with a value from the Sql DataSource in the design form with a label value entered by the user.
Hi, guys
I used an exported wcf service as a web service, try to use it as the reporting datasource,
[OperationContract]
DataSet GetTestReportData();

but it doesn't work, I tried use a pure asp.net web service and it works. can anyone help me to set the connecting string for datasource and query for dataset when it using wcf as the web service? Thanks in advance.

Hi All,
I have a question about the datasource that we create on the Report Manager. What is it used for? In the below connection string which is given in the "Connection String" text box of a datasource link:
"Data Source=ProdServer;Initial Catalog=Northwind"
What is this datasource used for? Is it used only to use the ReportServer database or even our queries incorporated in the RDL files will be run against this datasource? I think the latter should not happen because while creating RDL files also, we provide a connection string to run the stored procedures against that datasource.
Please let me know about the same.
Thanks a lot and let me know if the question is not clear.

View 2 Replies View RelatedI have this web store that I have been creating. When a customer goes to check out, he has to log in, then he is redirected to a page where he can view/add/or edit shipping and billing address. I have based all the sql statements on the profile username, adding records and retrieving them works just fine. When I go to change something in the info it uses an sql statement that updates based on "Where AccountUserName = @AccountUserName", I have @AccountUserName set to Profile("Username"). Keep in mind this works fine for adding new or bring up current records. I even put in code in the updated event for the sql data source to post a msgbox telling me how many rows were affected, it says 1 even though I dont see any change in the data. What am I doing wrong here, it's driving me nuts, its just a very simple update.
