ASP.NET - MSSQL Server Database Timeouts

Image
One of the most disturbing aspect of most database applications is connection timeouts. Most of us might have faced this at one time or other.

Let us say, you have an application that runs a lengthy stored procedure and you started getting a timeout error. You tried to optimize the procedure to the maximum possible extend. At this stage, it is desirable to have a way to extend the timeout so that the user will see the results even after waiting for a little longer.
