Using a FormView with a SqlDataSource, I'm attempting to Update data
by calling a stored proc in code behind. I was having trouble getting parameters
using Update Parameters in the SqlDataSource, but found a working solution by
coding the parameters.
The problem now is I'm getting an "Updating is not supported by data source 'XYZ' unless UpdateCommand is specified'.
I am trying to tie a sqlDatasource to a Stored Procedure. The stored procedure looks like...

i have a grid bound to sqldatasource control which gets its data from stored procedure. in page load event i code a dropdownlist where i take the selectedvalue parameter for the parameter query. only when a second dependant dropdownlist is selected (coded in dropdownlist1 selected event)is data returned ?
View 12 RepliesI have a stored procedure that creates a dynamic query. Sometimes the query is not built because there are no elements in the dynamic query. When the aspx page loads the SqlDataSource throws an error that the query is malformed. How can I catch this error, and handle it with a default message, before it returns the error to the aspx page?

My question is: I have update stored procedure in my database (simple update stmt) I am finding difficulty in writing a ADO.Net(C#) connection string for update stored procedure. i have 4 columns and i first 3 columns have constant values. The 4th column values needs to be updated. At the same time i need to increment and then update the table.

So I am getting this error message:
Cannot implicitly convert type 'System.Data.SqlClient.SqlParameter' to 'string' I have a stored procedure on SQL 2000 returning an email from a database table (aspnet_Membership). The email type from the table is nvarchar. I have a method (in C# in the code behind) that gets that value. But the debugger doesn't like the last line:
return returnEmail; // returnEmail is a string variable we created to capture the stored procedure's return value
I've tried doing returnEmail.toString() in several places, but still get the same error message for the last line of code (returning the email).
This is the stored procedure:

Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?
View 4 RepliesI am trying to allow users to grab their stored procs and call certain ones from within code. I can get the stored procedures and then fill a dropdown with them, but what I cannot find at this point is how to get the parameters that each stored procedure needs. I would like, once an SP is chosen from the dropdown to make a call to the db with that sp name and grab its paramter list so I can report what needs to be sent in to the user.

View 1 RepliesI am using Visual Studio 2008 and SQL Server 2008 and have added a SQL datasource to my form.
When I configure the datasource, I choose my connection string which looks like this in my webconfig:
<connectionStrings>
<add
name="PSFSPRD_ConnectionString"
connectionString="Data
The database I am using has a schema called EQB and as such, my stored procedures are named as EQB.usp_SelectFunds, EQB.usp_SelectAccount, etc.
On the select tab of the Configure Data Source screen, I choose to use a stored procedure. The dropdown shows my stored procedures, however, the schema name does not show up in front of the stored procedures in the drop down. I see only usp_SelectFunds, usp_SelectAccount, etc.
I select one of the stored procedures and when I click TEST, I get the message that the stored procedure is not found. If I instead choose to use a SQL statement instead on the configuration screen and enter EXEC EQB.usp_SelectFunds and click TEST, it works fine.
Why are my stored procedures not showing up correctly in the stored procedure drop down and how can I fix this?
Being new to using the declarative syntax of SqlDataSource I am trying to figure out a way to set the value of a parameter to a stored procedure. I have a Client_ID that is passed via the Request Object and I need to set the Client_ID before the stored procedure of the SqlDataSource is executed.
Does the stored procedure parameter have to be predefined in the ASPX markup or can it be added dynamically in the code-behind? Would anyone have an example that demonstrates the SqlDataSource markup with a stored procedure and parameter as well as setting that parameter value in code-behind?
I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate. I present the data in a FormView ItemTemplate using text boxes. When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.
I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course . This project is different in that I want to get the data from a stored procedure on a MSSQL server.
In my latest attempt, I can see the data in the datasets. I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value"
I include the code below. If someone could point me to an example I would be greatful. There has to be an elegant way of accomplishing this.

In an asp.net 3.5 web app, I have a page with the following markup/code (this is the brief version, but I believe I got all the relevant info).
[Code]....
The form contains 2 different record types, accessed using the paging controls, depending on the ParentSR field; a parent SR will be something like '1234' while its sub-record will be something like '1234.1'. There are only a few differences in the fields used between the 2 different record types and that is why they are stored in the same table. However, the activity depends on the record type. When browsing from the parent record to the sub-record, the itemtemplate loads fine (notice in the formview's datasource
query, that the sractivity_id field is being pulled along with the subquery value). But when going to edit the record, the page throws an error:
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentOutOfRangeException: 'ddlActivity' has a SelectedValue which is invalid because it does not exist in the list of items.
If i click 'back' and retry, it may take 3 attempts, but then the edittemplate will load just fine. I should also point out that this error does not always occur. I've been trying to figure this out for a couple months and it is driving me nuts, mainly due to the fact that I can't reproduce the error in development--it seems to only occurr in production. Anyone with any thoughts on what is going on?
a FormView that is linked to SqlDataSource1a Repeater control (inside the formview) that is linked to SqlDataSource2Thus representing a simple "1 to many" or "parent/child" relationship in the database!qlDataSource1 is simple in that it just retrieves a straight set of records from a table and they are displayed back in the FormView (nothing special happening there).SqlDataSource2 has parameters that filter the contents of the repeater based on the record that is shown in the Formview. This would normally be simple enough to set up by setting the parameter to the formview.selectedvalue property.HOWEVER - THE PROBLEM ARISES...The formview has multiple DataKeyNames because the table that the SqlDataSource1 links to has a compound key. So to filter the Repeater correctlySqlDataSource2 needs to map 3 parameters to 3 data key values in the formview.Any ideas how to do this?I've tried setting the SqlDataSource2 parameters to:
<SelectParameters>
<asp:ControlParameter ControlID="FormView1" Name="Parameter1" PropertyName="DataKey(0)" />
<asp:ControlParameter ControlID="FormView1" Name="Parameter2" PropertyName="DataKey(1)" />

However, when I try to access the results I get the following error:
System.NullReferenceException: Object reference not set to an instance of an object.
Upon debugging, there don't seem to be any results returned... but when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
How do I access this result so I can bind it to my fields?
