For some reason, I can't get the Gridview in the Updatepanel to refresh after I've made changes. can someone help?
I'm using the ToolkitScriptManager control and the UpdatePanel.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:GridView blah... </asp:GridView> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="DeleteButton" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="IBUpUp" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="IBDownDown" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="IBUp" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="IBDown" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="EditProfile" EventName="Click" /> </Triggers>
