Update Panel Refreshing Whole Page?

Hello Selva,

I am not clear about the problem but updatemode=conditional should be used,when one of the following conditions occurs:

• You call the Update method of the UpdatePanel control explicitly.
• The postback is caused by a control that is defined as a trigger by using the Triggers property of the UpdatePanel control. In this scenario, the control explicitly triggers an update of the panel content. The control can be either inside or outside the UpdatePanel control that defines the trigger.
• The ChildrenAsTriggers property is set to true and a child control of the UpdatePanel control causes a postback. A child control of a nested UpdatePanel control does not cause an update to the outer UpdatePanel control unless it is explicitly defined as a trigger.

The content which is inside the UpdatePanel that will be updated. 

Thanks

Thanks for your reply sudheer,,
I tried but it does not work out..

Solution1: Change the UpdateMode="Always" if possible.

Solution2: Keep it as same, where ever onchange functionality (server side) is there after code part is done then just add  updatepanel1.update() function.

Just check all HTML tags are closed properly or not.
