Hi All,

I am using a popup control extender inside a update panel and a save button for save data,and a datagrid to display those data.

<asp:Button ID = "submitCompensation" runat = "server" Text = "Add" CssClass = "deepBlueBtn"

OnClientClick = "return VerifyCompensation();" OnClick = "submitCompensation_ServerClick" />

and in cs page insert data into DB  then Bind the grid by calluing a method

my problem is that the whole page is refreshed. But i want to refresh the updatepanel  only .

Help me.

Thanks.

Set UpdateMode Property of UpdatePanel to Conditional the call Update()  method of UpdatePanel

http://asp.net/AJAX/Documentation/Live/mref/P_System_Web_UI_UpdatePanel_UpdateMode.aspx

http://asp.net/AJAX/Documentation/Live/mref/M_System_Web_UI_UpdatePanel_Update.aspx

If the UpdateMode property is set to Conditional, and 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.
