Displaying TRACE data

by  putrtek  Posted    (Edited  )
I Complied this tip from several places on the Internet

Add this code to the very beginning of your Page Load event...
Code: 
If Request.QueryString("trace") = "true" Then
    Trace.IsEnabled = True
End If

Then add

Code: 
&trace=true

To the end of your URL when ever you want to get TRACE information


Here is a addon to this...

If you are updating data and want to see what paremeters are being passed to your Stored procedure

Add this proc to the code behind file
Code: 
      Protected Sub SqlDataSource_Insert_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles SqlDataSource_Insert.Inserting
        For x As Integer = 0 To e.Command.Parameters.Count - 1
            Trace.Write(e.Command.Parameters(x).ParameterName)
            Trace.Write(e.Command.Parameters(x).Value)
        Next
    End Sub

This proc assumes your data source is called 'SqlDataSource_Insert' change this is it's not.

This proc combined with the '&trace=true ' from above will write out all the parameters being passed by your page to the TRACE

Pretty cool...
