Sys.WebForms.PageRequestManagerTimeoutException - The server request timed out

Dear friends , above error will be shows in different cases . I faced same issue regarding server timeout with ASP.NET loader event. Error & Cause : I got this error: "Sys.WebForms.PageRequestManagerTimeoutException The server request timed out" from the Ajax Extension framework. Its occurred because the export operation was relatively long (something like 2 minutes) and the Ajax Extension Callback framework had a timeout. How to solve this problem? To solve this problem we can increase the timeout. You can change the timeout time by adding a new property to the script manager control. This property is called AsyncPostBackTimeOut and it can help us to define the number of seconds before the request will throw a request timeout exception * . For example if you want that the timeout will take maximum 10 minutes your code should be look like this: < asp : ScriptManager ID ="ScriptManager1" runat ="server" AsyncPostBackTimeOut
