SqlDataSource - SelectCommand with session variable filter

ASP.NET 2.0 framework

I'm trying to list all user related entries when the user visits the page. I have a session variable set with the visitor in session. Now I want to query the database with that ID. It seems to be executing, but no results are being returned (I'm displaying the contents in a seperate code section).

Please help!

<asp:SqlDataSource
ID="UserReports" 
runat="server"
ConnectionString= "<%$ ConnectionStrings:MyConnectionString %>"
SelectCommand = "SELECT [ID], [ReportName], [ReportPath] FROM [Pan].          
[dbo].[Reports] WHERE ([VisitorID] = @VisitorID)"
OnSelecting  = "SqldsExample_Selecting">

<SelectParameters>
    <asp:Parameter Name="VisitorID" Type="String"/>
</SelectParameters>    
</asp:SqlDataSource>

On the code behind:

Sub SqldsExample_Selecting(sender As Object, e As      
SqlDataSourceSelectingEventArgs)

UserReports.SelectParameters.Add("@VisitorID", Session("VisitorID"))

End Sub
Solution

  • Don't use <asp:Parameter>.You should be using <asp:SessionParameter> to access the session variable directly:

    <SelectParameters>
    <asp:SessionParameter Name="VisitorID" SessionField="VisitorID" />
</SelectParameters>
