how to write the exception with out change of the code in as

i have four pages as follows

trips.aspx

adhoc.aspx

for the above four page i did not write exception. with out change of the code how to write the exception for all the four pages in asp.net

for that how can i do in asp.net

You can use web.config to add custom error page. But one problem is you cannot log the exception.

<configuration>
<appSettings/>
<connectionStrings/>
<system.web>
<compilation debug="true" />
<customErrors mode="On"
defaultRedirect="DefaultRedirectErrorPage.aspx">
<error statusCode="404" redirect="Http404ErrorPage.aspx"/>
customErrors>
system.web>
configuration>

So it is better to use Global.asax to get exception and logit.

void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
// Get the exception object.
Exception exc = Server.GetLastError();
// For other kinds of errors give the user some information
// but stay on the default page
Response.Write("
Global Page Error
\n");
Response.Write(
"
" + exc.Message + "
\n");
Response.Write("Return to the " +
"Default Page\n");
// Log the exception and notify system operators
ExceptionUtility.LogException(exc, "DefaultPage");
// Clear the error from the server
Server.ClearError();
}

Hi Narasiman,

I think you cannot do this without touching the code, Surely you need to touch the code to implement custom error handling or common try catch exception.

You may find some other way to do this. If I know , I will reply soon.
