ASP.Net VB Redirecting to an error page on SQLDataSource timeout

My page has the following SQLDataSource

<asp:SqlDataSource ID="dsResults" runat="server"
    ConnectionString="<%$ ConnectionStrings:Activist_InsightConnectionString %>"
    EnableViewState="False" >

At the moment I am setting the timeout to be very low to force at timeout, ultimatly this number will be higher.

Protected Sub dsResults_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles dsResults.Selecting

    e.Command.CommandTimeout = 12

  End Sub

I want a friendly error page if the Query times out, so I tried the following:

      dsResults.SelectCommandType = SqlDataSourceCommandType.Text
      dsResults.SelectCommand = BuildMasterQuery()
    Catch sqlEx As SqlException
      Response.Redirect("SearchTimeout.aspx?queryid=" & Request.QueryString("queryid"))
    Catch Ex As Exception
      Response.Redirect("SearchTimeout.aspx?queryid=" & Request.QueryString("queryid"))
    End Try

However when the query times out I do not redirect to the speciifed page, but I get an ASP.net error page.

What am I doing wrong?

This type of error has to be handled by the application error handler.
The event must be created in your global.ascx
from http://msdn.microsoft.com/en-us/library/vstudio/994a1482(v=vs.100).aspx
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
    Session("CurrentError") = "Global: " & _
End Sub

Ok this approach looks promising.

How do I tell if the error has come from the page that I am interested in?

in the application error event use something like this

Dim con As HttpContext = HttpContext.Current
con.Request.Url.ToString() 'will contain the page throwing the exception
