Ok This is driving me nuts, I am not sure if I forgot to do something or if there is a bug in the ToolKit .... 1.0.10201.0
My problem is that the popup control extender causes the update panel to do full page post backs instead of async...
I comment out the popup control extender then the update panel refreshes asyncronasly...
can any one tell me whats wrong please :)
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<div>
</div>
<asp:Panel ID="pnlCancel" runat="server" Height="50px" Width="125px">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:Label ID="lblDate" runat="server"></asp:Label>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="GenerateAsyncDate" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" />
</Triggers>
</asp:UpdatePanel>
</asp:Panel>
comment this and try
<cc1:PopupControlExtender ID="PopupControlExtender1" runat="server" TargetControlID="Label1"
PopupControlID="pnlCancel" Position="Right"/>
</form>
