Responce.redirect(url) ThreadAbortException occured

The ThreadAbortException is thrown when you make a call to Response.Redirect(url) because the system aborts processing of the current web page thread after it sends the redirect to the response stream.

use following way to solve ThreadAbortException :-

//set globle varible as
private bool m_bIsTerminating = false;
protected void NavigateTo(string url)
{
Response.Redirect(url, false);
HttpContext.Current.ApplicationInstance.CompleteRequest();
m_bIsTerminating = true;
}

protected override void RaisePostBackEvent(IPostBackEventHandler sourceControl, string eventArgument)
{
if (m_bIsTerminating == false)
base.RaisePostBackEvent(sourceControl, eventArgument);
}

protected override void Render(HtmlTextWriter writer)
{
if (m_bIsTerminating == false)
base.Render(writer);
}
