Updatepanel in ASP.NET (Ajax)

I think whatever 'DX Roster' told is correct. If it is working then it is fine. But still your page is getting refreshed, I think you have not used "AJAX Enabled Website" while creating your project. Select "AJAX Enabled Website" while creating new project. Just try this once...

1. If your website was not Ajax Enabled earlier, then you can still convert into one by adding necessary configurations in your web.config file. Easiest way would be to create a dummy 'Ajax enabled website' and copy the missing tags from this website into old one that you want as Ajax enabled.

2. Set EnablePartialRendering="true" in your ScriptManager.

3. You don't need to define any 'Trigger' in Update Panel for what you are trying right now.

<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
</asp:ScriptManagerProxy>


<asp:UpdatePanel ID="updtPnlWarErr" runat="server" RenderMode="Inline">
<ContentTemplate>
<table border="0" cellpadding="5" cellspacing="0" class="clsDisplayTable" style="width: 95%;">
<tbody>
<tr>
<td>
<asp:Label ID="lblWarning" runat="server" CssClass="clsWarning" Font-Bold="True"></asp:Label>
</td>
</tr>
<tr>
<td>
<asp:Label ID="lblError" runat="server" CssClass="clsText" Font-Bold="True" ForeColor="Red"></asp:Label>
</td>
</tr>
</tbody>
</table>
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="btnSave" />
<asp:AsyncPostBackTrigger ControlID="btnDeleteTop" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="btnCancel" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
