Display custom error in error.aspx page in asp.net webforms

Question

I want to show the Custom Errors in error.aspx page when any error occur. Its redirecting to error.aspx when error happens. But not showing the message.

I set web.config like

<customErrors mode="On" defaultRedirect="/error.aspx" redirectMode="ResponseRewrite">
  <error statusCode="404" redirect="/notfound.aspx" /></customErrors>

Is there any way to show the error message in error.aspx page.

You can call the GetLastError() and show the error.

// Get the last error from the server
var ex = Server.GetLastError();

if (null != ex)
{
   // get and render here the error, there are a lot more info to see.
   txtLiteral.Text = ex.Message;
}

// and clear the error from the server
Server.ClearError();

But I suggest to write it down to a log, and not show it to your users. Also locally there is not reason for custom page, leave it as they are to see the errors.
