Here is what I'm trying to do: Click a
button on my page, which in turn makes (2) things happen:
Display a ModalPopup to prevent the user from pressing any buttons or changing values
Call my code behind method, hiding the ModalPopup when finished
Here is the ASP markup:
<asp:UpdatePanel ID="UpdatePanel2" runat="server" ChildrenAsTriggers="true"
UpdateMode="Always">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSaveData" EventName="Click" />
</Triggers>
<ContentTemplate>
<asp:Panel ID="pnlHidden" runat="server" style="display: none;">
<div>
<h1>Saving...</h1>
</div>
</asp:Panel>
<cc1:ModalPopupExtender ID="modalPopup"
BackgroundCssClass="modalBackground" runat="server"
TargetControlID="btnSaveData" PopupControlID="pnlHidden">
</cc1:ModalPopupExtender>
<asp:Button ID="btnSaveData" runat="server" Text="Save Data"
OnClick="btnSaveData_Click" />
</ContentTemplate>
</asp:UpdatePanel>
Now, here is my code behind C# code:
protected void btnSaveData_Click(object sender, EventArgs e)
{
UpdateUserData(GetLoggedInUser());
modalPopup.Enabled = false;
}
Why doesn't this work? The ModalPopup displays perfectly, but the btnSaveData_Click event NEVER fires.
