用于存储过程的SqlDataSource的QueryStringParameter

Question

I have a SqlDataSource and want to filter it based on query string. However using SelectParameters / QueryStringParameter , it doesn't seem to pass the value to the stored procedure.

The data source is configured like this:

<asp:SqlDataSource runat="server" ID="sqlGetDetails"
     ConnectionString='<%$ ConnectionStrings:SqlDbConnectionString.ConnectionString %>'
     SelectCommand= "GetDetails" SelectCommandType="StoredProcedure">
     <asp:SelectParameters>
         <asp:QueryStringParameter Name="AppID" QueryStringField="AppID" DbType="String" Direction="Input" DefaultValue="" ConvertEmptyStringToNull="true"/>
     </asp:SelectParameters>
</asp:SqlDataSource>

It fails with error:

Procedure or function 'GetDetails' expects parameter '@AppID', which was not supplied

The stored procedure was created with code like this:

CREATE PROCEDURE [dbo].[GetDetails]
    @AppID NCHAR(40)
AS
BEGIN
    SELECT * 
    FROM dbo.Details 
    WHERE dbo.Details.AppID = @AppID
END
GO

Stack trace:

Answer 1

Your SelectCommand must look like:

From:

SelectCommand= "GetDetails"

To:

SelectCommand= "GetDetails 12"

12 serve as a parameter.

I never tried if you can pass something like

SelectCommand= "GetDetails AppID//Serve as the value".. Just think about it.
