Getting a Timeout Error


A

Andrew Cooper

Greetings,

I've got a website that has several pages with DataGrid controls on
them. The controls are bound to Object Datasources. On one of the
pages I keep getting a "Timeout expired. The timeout period elapsed
prior to completion of the operation or the server is not responding."
error. The data is being filled from a Stored Procedure on an SQL
Server. When I run the Stored Procedure on the actual server, it is
only taking 24 seconds or so to run and the timeout setting on the
ASP.NET website is set to 120 seconds. Other pages on the site that
have similar queries are working fine. Is there anything else that
might be causing the timeout?

Below is a copy of the error message...

responding.]

At a glance it looks like the timeout is not from your page, but from your
Database connection.
Try adding a timeout entry in the connectionstring or setting the
DbConnection.ConnectionTimeout property.

Cheers,
Louis

That was it. I should have known that. Sometimes its the stupid,
little things that get you.

Thanks, Louis.
