ThreadAbortException

Question

this is my button click sub

Protected Sub abc_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnsavecurrent.Click
    Try
        If Not Page.IsValid Then Exit Sub
        Saveabc()
        Response.Redirect("abc.aspx")
    Catch exab As Threading.ThreadAbortException
    Catch ex As Exception
        ReportError(ex, Session, Request)
    End Try
End Sub

after going to response.redirect, it moves to next line of ThreadAbortException and doesnt goto the abc.aspx. it just says session expired. how do i make it goto the abc.aspx?

Answer 1

Its the way Response.Redirect is implemented, Response.End generates a ThreadAbortException for notifying the processing engine.

This article has a work around for solving this. In general you probably don't want to catch ThreadAbortException if you are doing a Redirect.

I believe this is also documented in MSDN as well.
