How do I force full post-back from a button within an UpdatePanel?
Solution 1:
You can use the Triggers property of the UpdatePanel to register actions that trigger a full postback.
Add a PostBackTrigger object to that property, containig the ControlID of the control which needs to trigger a full postback.
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
...
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="myFullPostBackControlID" />
</Triggers>
</asp:UpdatePanel>
Solution 2:
Just adding this because nobody else has. It is possible to do this in code-behind in one line of code without any of the above methods. Just put this in page_load:
Visual Basic
ScriptManager.GetCurrent(Me).RegisterPostBackControl(myButtonID)
C#
ScriptManager.GetCurrent(this).RegisterPostBackControl(myButtonID);
Solution 3:
From here:
Use the PostBackTrigger control to enable controls inside an UpdatePanel to cause a postback instead of performing an asynchronous postback.
<Triggers>
<asp:PostBackTrigger ControlID="controlID" />
</Triggers>
