I tried to your code for print panel on host server. I got this error.

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

How can I solve this error?

I have a panel with multiple web controls...when i used your code its throwing error as "The Controls collection cannot be modified because the control contains code block."
in frm.controls.add(controlToPrint) how can i solve dis?

Please give me reply i am using this code but its not working in my system error is the control with ID 'RadGrid1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

"The Controls collection cannot be modified because the control contains code block." To avoid this error you should copy and paste all java script codes after HTML tag.
