Your repeater is missing the ItemTemplate tag
<asp:UpdatePanel ID="updatePanel" runat="server">
<ContentTemplate>
<asp:Repeater ID="rptrtest" runat="server" OnItemCommand="rptrtest_ItemCommand" OnItemDataBound="rptrtest_ItemDataBound">
<ItemTemplate>
<div> <asp:TextBox ID="txtName" runat="server"/> <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" > </asp:Button> </div>
</ItemTemplate>
</asp:Repeater>
</ContentTemplate>
</asp:UpdatePanel>

The ModalPopupExtender wires the btnCancel button to trigger the a popup an UpdatePanel. The UpdatePanel is a cancel confirmation which contains a Yes button and a No button. After clicking the No button, the panel is closed but the btnCancel no longer trigger the popup when being clicked again. The Yes button works and triggers the server side YesButton_Click event. Here is my code. Thanks for your help.

I'm not 100% positive but it appears that Extender and Extended controls must reside in the same UpdatePanel. So if you move your Cancel button and ModalPopupExtender control inside the UpdatePanel, it should work as expected.

I have edited the code... Now what should I do? I have the linkbutton inside contenttemplate. Still a postback is happening
Any postback coming from any control outside an UpdatePanel will trigger a full postback unless you add those events as triggers of your UpdatePanel
In your example,
<asp:LinkButton ID="btnSendChat" runat="server" CommandName="Insert" CommandArgument='<%# Eval("Username2") %>'>Send</asp:LinkButton>
It's outside of the UpdatePanel and since you do not have triggers in your panel that will always cause a full postback
Solutions:
Approach 1
Place the LinkButton inside the UpdatePanel.ContentTemplate
Approach 2
Add triggers to your UpdatePanel
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSendChat" EventName="Click" />
</Triggers>
I'm trying to use a modal popup extender on my page so when I click a button, it must show a panel. Here is what I have:
<asp:UpdatePanel runat="server" ID="updPanel">
<ContentTemplate>
<ajaxToolkit:ModalPopupExtender ID="mpeEmailComplete" runat="server" TargetControlID="btnTesting"
PopupControlID="pnl" OkControlID="btnOk"
BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>
<asp:Panel ID="pnl" runat="server" style="display:none;">
<asp:UpdatePanel ID="udp" runat="server">
<ContentTemplate>
<asp:Panel runat="server" ID="pnlEmailComplete" Visible="false">
<asp:Label runat="server" ID="lblTest" Text="Testing testing testing"></asp:Label>
<asp:Button runat="server" ID="btnOk" Text="OK" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
<asp:Button runat="server" ID="btnTesting" Text="Testing"/>
</ContentTemplate>
</asp:UpdatePanel>
but i can't get the panel to popup when the button is clicked. Anybody know why?
Your innermost panel has Visible=false.
<asp:Panel runat="server" ID="pnlEmailComplete" Visible="false"> *(change here)*
So, when you press the TESTING button, the ModalPopupExtender correctly causes the outer panel to display, but it's displaying an invisible inner panel, hence you see nothing on screen.
<asp:Panel ID="pnl" runat="server" style="display:none;"> *(this is ok)*
To fix, just yank the Visible=false from the outer panel (pnlEmailComplete)
Hope that helps!
Do you have any JavaScript errors and is pnl.Visible=False; set on the server-side anywhere?
Make sure you have the AjaxControlToolkit referenced properly, NuGet is the easiest way to add the reference.

In my form I have a label and button control.
By default the label is visible. When a user clicks on the button I have made the label to visible false.
For simple button it is working, but when I add an updatePanel to button the event is getting fired but the label is not getting to visible false. Just try this, and please can anybody tell me why this is happening and the solution for this.
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:fileupload ID="Fileupload1" runat="server"></asp:fileupload>
<asp:Label ID="Label1" runat="server" Text="Label" ></asp:Label>
<asp:UpdatePanel ID="up" runat ="server" >
<ContentTemplate >
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
</ContentTemplate>
</asp:UpdatePanel>
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write("hello");
Label1.Visible = false;
}
From the looks of it you need to wrap your label within the update panel as well.
Try
<asp:fileupload ID="Fileupload1" runat="server"></asp:fileupload>
<asp:UpdatePanel ID="up" runat ="server" >
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Label" ></asp:Label>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
</ContentTemplate>
</asp:UpdatePanel>
An update panel will update a section of your page. Your label wasn't included within the updatepanel so would never get updated with your new value.
I suggest that you only wrap the label with the UpdatePanel and set the UpdateMode to "Conditional".
<asp:UpdatePanel ID="up" runat ="server" UpdateMode="Coditional" >
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" />
</Triggers>
</asp:UpdatePanel>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
