Problem Binding Lisbox Value With The Database Column?
Jan 30, 2008
Hello Friends..
I m using vwd 2005 express along with sql express.
I have a web form with different server controls like textboxes, labels, radiobuttons, listboxes etc.
lets focus on listbox.
1..For example lets say,ListBox contains 5 email addresses of the user.
Now my main problem is when i submit my webform,all my data from
textboxes, radiobuttons etc gets stored into the sqldatabase.
But the data from my ListBox doesnot get stored into the database.
But when i manually select a single email address from the listbox the email address in this case gets saved in the database.
But as soon as i choose multiple email address then in this case only
the first email address only gets saved but not the rest.
How to over come this problem? I have a column named "email" in my table in the database.
Can some one explain me this with the code(C#)..
2..And my 2nd question is i dont want to manually select the data from the listbox so that it gets saved into the database.
I want all the email address in the Listbox gets automatically selected as soon as i click on the save button at
the end of my web form.
I'm trying to use a SQL 2000 view in one of my sources. The view isnt anything special --- just three tables that have been unioned together. All these three tables have the EXACT same datatypes as well as column names. There are no constraints on these tables (yet). There is an identity seed on the first ID column. However, when I try to access this view, it generates the following error:
Server: Msg 4502, Level 16, State 1, Procedure MyView, Line 5 View or function 'MyView' has more column names specified than columns defined. Server: Msg 4413, Level 16, State 1, Line 1 Could not use view or function 'MyView' because of binding errors.
I want to be able to have an authorized person set or change the default values of a table column in a SQL Database. I have a stored procedure that sets the default which works fine: ALTER PROCEDURE [dbo].[addMyConst]ASBEGINALTER TABLE [dbo].[tbl1]ADD DEFAULT 70 FOR [Auto_ourlim]END(I still need to put parameters in so that I can run the stored procedure from a form, but for now....) To change it I know that I have to drop the constraint first like this: ALTER PROCEDURE [dbo].[dropmyValue]ASALTER TABLE [dbo].[tbl1] DROP CONSTRAINT [Auto_ourlim] The problem is that when I execute the procedure I get the error that "Auto_ourlim" is not a constraint so it does not drop the Default Value. When I go over to SQL Server Management Studio Express I can see why: If I open up the table and open up the Constraints the constraint is "DF__tbl1__Auto_ourli__5FB337D6". I could change the DROP CONSTRAINT to this, and that works, but it changes every time I add the new DEFAULT VALUE. I don't know how to get around it. Is there a way to put wildcards around "Auto_our" in DROP CONSTRAINT [Auto_ourlim}? Any suggestions would be welcome...even if there's a totally different way to do it. What I'm trying to ultimately accomplish is this: Column1 (AutoLimits) would be user insert to the database and then in the database it would MINUS Column2 (Auto_ourlim - set with the default value) = Column3 (Difference - a computed field in the database) Steve
I have a little question. I have an application which interfaces with a SQL Express Database. On a form, I want to bind a control which is made of several Radio buttons to a table column which is in fact a varchar(1). This is the picture:
Table column: OptVisualRpt varchar(1)
Screen control: 2 radio buttons
rb_VisRPTbImp_O for "yes"
rb_VisRPTbImp_N for "no"
I'm really scratching my head as how I can bind a single table column to my radio buttons controls. I think that I just can't this way but rather have to use an intermediate variable or control.
Solution 1?
I thought of using a local variable that I would set to "y" or "n" following "CheckedChanged" events fired from radio buttons but I don't know how to bind this variable to my table column.
Solution 2?
I thought of placing a hidden text control into my form, which one would be binded to my table column, that I would also set to "y" or "n" following "CheckedChanged" events fired from radio buttons.
Any of these solutions which would be feasible or any more neat way to do it?
I am new to .net and I am using Visual Web Developer 2005 Express with SQL Server 2005 Express. What I would like to do is connect to my SQL database (which resides in the app_data folder) and open a table and pull out a field and place it in either a textbox or label on the page. No editing or deleting. Just simple one field binding. By the way, I can do this with all the cool built-in tools of VWD, but I want to know how to do it all by hand. I would really appreciate it if someone could help me out.
Code : protected void Page_Load(object sender, EventArgs e) { Session["ID"] = "2"; string strConnString = ConfigurationManager.ConnectionStrings["BSDConnectionString"].ConnectionString; var con = new SqlConnection(strConnString); using (var sda = new SqlDataAdapter())
[Code] ....
That was my code , now lets see what my problem is :
I am getting only two dates in a single row from sql to my asp.net webform and then bindng those dates in jQuery UI Datepicker. Now if i set session to 1 then date picker works well but if i put session = 2 , it shows the end date till 2020 which is wrong.
Below are the dates which are fetched from database and i have copied here for your ease.
When Session["ID"] = "1"; Start Date : 01/07/2014 00:00:00 End Date : 05/02/2015 00:00:00
When Session["ID"] = "2";
Start Date : 07/04/2015 00:00:00 End Date : 27/08/2016 00:00:00
I have set my mindate to startdate and maxdate to end date. please check and see where the error is happening.
Also point of interest is that if i don't fetch values from database and use only List<string> in my web method then every thing works well. like this :
[WebMethod] public static List<string> GetDates() { List<string> arr = new List<string>(); arr.Add("2014-07-01"); arr.Add("2015-02-05"); return arr; }
Hi all I have a form view which uses a SQL data source control to retrieve it's data from the sql express database the form view is used for view,edit,delete and insert data into the database in the insert mode I have two dropdownlists, where the second one is depending on the first one to retrieve the correct data from the data base BUT when selecting a value in the first dropdownlist it give me the following erro: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
Please How can do this any help is appriciated bye
Hey guys, Am in need of help please, basically the program im working with at the moment is when you add a New Contract, it will grab the Contract Number you have entered, Post it over to another page, then using that number bind a Gridview. The SQL being "SELECT Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent FROM ECS_Contracts_Test WHERE Contract_Number = " & conNoVar (this being the Contract Number of the recently added Contract), however then it comes to Bind the Grid it kicks up an System.Data.SqlClient.SqlException: Syntax error converting the nvarchar value '2009P7899' to a column of data type int.But the Column Contract_Number is set to Varchar and all I really want to do is to create this gridview using this criteria and not convert anything! The Contract_ID is an int, which is needed as I increment it. Heres the error code: Public Sub BindtheGrid()'Bind the Contract Grid, where ContractID is used Dim SQL As String = "Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent" Dim objConn As SqlConnection = New SqlConnection(ConnectionString) Dim cmdstock As SqlCommand = New SqlCommand("SELECT " & SQL & " FROM ECS_Contracts_Test WHERE Contract_Number = " & contractQueryID, objConn) cmdstock.CommandType = CommandType.Text objConn.Open() GridView1.DataSource = cmdstock.ExecuteReader() GridView1.DataBind() objConn.Close() End Sub If you need any more information then please let me know. Mucho Aprreciated

Now i know sql, but how do I store data from a website and all, I have no clue, someone give me basic steps on how to go about doing this pleaseeeeee!!!
I have this stored procedure that almost works: set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go
ALTER PROCEDURE [dbo].[udForumTopicMessageByForumTopicID] @ForumTopicID int AS SELECT ftm_parent.ForumTopicMessageID AS "ForumTopicMessageID", ftm_parent.ForumTopicID AS "ForumTopicID", ftm_parent.ContactID AS "ContactID", ftm_parent.MessageTitle AS "MessageTitle", ftm_parent.MessageText AS "MessageText", ftm_parent.ApprovedInd AS "Approved", ftm_parent.ReviewedInd AS "ReviewedInd", ftm_parent.ParentMessageID AS "ParentMessageID", ftm_parent.OwnerCompany AS "ForumTopicMessageOwnerCompany", ftm_parent.CreateUser AS "ForumTopicMessageCreateUser", ftm_parent.UpdateUser AS "ForumTopicMessageUpdateUser", ftm_parent.CreateDate AS "ForumTopicMessageCreateDate", ftm_parent.UpdateDate AS "ForumTopicMessageUpdateDate", '('+CAST(ChildResponseCount As VARCHAR(10))+')' As "ChildResponseCount", (T_Contact.Lastname + ', ' + T_Contact.Firstname) As "ContactName" FROM [T_ForumTopicMessage] as ftm_parent INNER JOIN [T_Contact] ON [T_Contact].ContactID = ftm_parent.ContactID Left JOIN (Select COUNT([T_ForumTopicMessage].ForumTopicMessageID) As "ChildResponseCount", MAX([T_ForumTopicMessage].ParentMessageID) AS "ParentMessageID" FROM [T_ForumTopicMessage] WHERE [T_ForumTopicMessage].ParentMessageID = ftm_parent.ForumTopicMessageID group by [T_ForumTopicMessage].ForumTopicMessageID) as ftm_child ON ftm_parent.ForumTopicMessageID = ftm_child.ParentMessageID WHERE ftm_parent.ForumTopicID = @ForumTopicID ORDER BY ftm_parent.CreateDate See the purple ftm_parent.ForumtopicMessageID. If I hard-code that to a 2, this works. With the fieldname there, SQL Server Management Studio says: Msg 4104, Level 16, State 1, Procedure udForumTopicMessageByForumTopicID, Line 9 The multi-part identifier "ftm_parent.ForumTopicMessageID" could not be bound. If any experts out there can help me out with this, I'm sure it wouldn't take much to fix.
i want to count the number of times a particular data occurs in a table and display that data in a listbox
initially i planned to count the number of occurrences and bind that number to a variable for further manipulation but i have no idea how to do the binding part
To do this successfully do I need to backup the Service master, Database master, and database itself from the the Source server, then restore all three of them on the destination server?
(I'm concerned that restoring the source Service Master key to a new target server with an existing sql 2005 install will screw things up big time.)

Hi all, The Scenario: Database1:Table1(callingPartyNumber,originalCalledPartyNumber, finalCalledPartyNumber, DateTimeConnect, DateTimeDisconnect, Duration) Database2:Table2(Name,Number) Output in Gridview:
callingPartyNumber Name originalCalledPartyNumber finalcalledPartyNumber dateTimeConnected dateTimeDisconnected Duration (HH:MM:SS) I bind gridview programatically using DataTable and stored procedures. The data comes from a table (Table1) in a database (Database1) on SQL Server. The gridview displays fields callingPartyNumber, originalCalledPartyNumber, finalCalledPartyNumber, DateTimeConnect, DateTimeDisconnect and Duration in this order. All the columns in this gridview are databound columns. I have another table (Table2) in a seperate SQL Server database (Database2) but on the same server which maps the callingPartNumber value with the name attached with that number. Note that the field names in Table2 are different from the field names in Table1. Is it possible to display the Name field also in the gridview after the first field callingPartyNumber and then the other fields. Its like data coming from two tables into the gridview. Thanks
Hi all. I have a label on my page and I want to bind it to a field in a table. The catch is that I want to bind it to the last row in the table. I think I can use the custom binding, but I don't know how to bind to the last row. Any Suggestions ? p.s. The page is tied to an SqlDataSource that retrieves the data from the above table. Thanks in advance.
Hi, I am using a SQL DataSource with a few parameters. I need to specify the value of the parameters at run time but I need a custom way to do it as the value needs to be calculated not come from Cookie, Control, Form, Profile, QueryString or Session. Is there a way to bind your own value to these parameters. For instance if I had a variable how would I bind that to the parameter? At the moment i am doing the following which works but I dont think it is the correct way dsMyDataSource.SelectParameters["MyParameter"].DefaultValue = MyCalculatedValue; In previous projects i have added a value to the Session and then bound the parameter value to the session but that doesnt seem like a good solution either. Thanks for any help you can give. Martin
Hi All I am new to VS 2005 and ASP.NET. I used to use Dreamweaver to design but now I am trying VS. What I want to do is to display data retrieved with a SqlDataSource in a web page. I know how to do it by binding it to the various controls (Grid, DataList, DetailsView, FormView, Repeater.) available but how can I display it without using any of the mentioned (Grid, DataList, DetailsView, FormView, Repeater)? Any help apprecited.
I am real new to SQL Server. We are using SQL Server 2000.
My objective is to get a list of all store procedures for specific database. To accomplish this, I programmatically create a connection to the 'master' database where the sp resides, create a callablestatment for 'sp_stored_procedures' ({call sp_stored_procedures(?,?,?)}). I am passing in null, null, and the database name. When I execute the query, I get the below error:
Code:
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Invalid parameter binding(s). at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source)
When I made the connection to the master database, I used one of the existing users from the master database.
I looked at the store procedure and verified the sp has 3 input parameter. The first two can be null.
I am not sure why I can not run this sp. I am wondering if we have the database setup properly. Any help or suggestions would be well worth it at this point.
Greetings all,I am a network security professional rather than a MS SQL admin, so Iapologize in advance if this is a bit of a basic question for thislist. I also cross-posted this to microsoft.public.sqlserver.server,so sorry if anyone's read it already.I know an admin setting up a SQL server that will only beaccesible by a webserver running on the same host (not happy aboutrunning private vs publicly avaialable services on the same host , butit's what we've got). As such, I'd like to recommend to him that theSQL server only listen on the localhost ip, 127.0.0.1, thereby makingit inaccesible to the outside world. I looked around the MSknowledgebase but couldn't find a clear document stating how to dothis. Is it even possible? Is there a better option for thisconfiguration?It's been suggested that firewalling is the only option, but I'd reallylike to do *both* (firewall & bind to localhost). The firewall in thiscase will have to be host-based instead (software) instead of hardwarefor non-technical reasons, so additionally if anyone recommends asoftware firewall they use for this purpose I'd appreciate it. My firsimpulse is to recommend Tiny, but I've never used a software firewallfor an MS SQL/Web server before.Thanks,Brian
I'm implementing some database formatting and I need that values withina column have certain limits ... let's say for example, they shouldn'tbe <0 or >10000, but in the case I'm inserting values bigger then 10000I would like that MSSQL "clip" this value to the upper limit (10000 inthis case) and the same with the lower limit (zero in this case).Is that possible? or SQL just respond me with an error when the valuesgo beyond those limits and will abort the transaction?Can someone put some light on this please???Nacho
Hi to all, As I am going to deal with a huge number of database tables, I thought that drawing their diagrams will be the most professional way of keeping track of what I am doing. So In Enterprise Manager using the Wizard I made it to be drawn nicely.
But I have a problem now. I see that the relations defined among the tables are represented correctly but the line connecting the two table is drawn randomly. I mean the starting point of the line doesnt start from the column having the primary key and doesnt end near to the column having the foreign key. Viewing my diagram I want to see the lines to start and end showing the 2 related key columns. Is there a way to accomplish this like setting an option, clicking somewhere or should I try to drag the lines to manually? Thanks in advance
