            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<asp:Button ID="CancelButton" runat="server" Text="No"
                onclick="CancelButton_Click" />

        </asp:Panel>

Not clear on your issue. Is AutoEventWireup set to true? Did you debug and see if the execution is getting on server side?

hi, try this one this will work

XML

<div>
    <asp:ScriptManager runat="server" ID="ScriptManager1"></asp:ScriptManager>
    <cc1:ModalPopupExtender ID="MPE" runat="server" CancelControlID="btnCancel"
    TargetControlID="HiddenField1" PopupControlID="MessageDiv" BackgroundCssClass="popupbg">
     </cc1:ModalPopupExtender>
<asp:HiddenField ID="HiddenField1" runat="server" />
<div runat="server" id="MessageDiv" style="width: 450px;display: none;">
<asp:Label ID="lblMsg" runat="server"></asp:Label><br />
<asp:Button ID="btnOK" runat="server" Text="Ok" OnClick="btnOK_Click" />
<asp:Button ID="btnCancel" runat="server" Text="Cancel" />

    </div>
    </div>

on code behind ie in your button click

MIDL

lblMsg.Text = "You will Never  shutdown the real napster";
           MPE.Show();

hi try this

// For this Quest right now when i am clicking CancelButton
//nothing is happening .

On CancelButton_Click event

//if you want to generate Cancel click event in code behind you need to remove 

CancelControlID="btnCancel" from you Model Pop Up Like 

<asp:modalpopupextender id=""Panel2_ModalPopupExtender"" runat=""server"" targetcontrolid=""LinkButton1"<br" mode="hold" xmlns:asp="#unknown" />            PopupControlID="Panel2" OkControlID="OkButton" DynamicServicePath="" Enabled="True">
        </asp:ModalPopupExtender>

HI Remove CancelControlID="CancelButton" property of your modalpopup extender then the click event of the button will work.

What happens when set the OkControlID to the button is the modalpopup extender suppresses the click event of the button.This will be helpful if you handling the data insertion in ajax way.

But in your case you want the click event of the button to be fired,so removing the above said property will make your button event fire.

You will need a dummy button control to achieve this behaviour.
Steps would be:

1. Have your normal cancel button on the page
2. Have a invisible dummy cancel button with the CSS Style as display:none (strictly not Visible="false")
3. Have your popup panel on the page
4. Have your modal popup extender on the page with TargetControlID as your dummy cancel button ID

Now when you click on the normal cancel button (click event in the code behind),

Cancel button click event
{
//Do whatever stuffs as disabling button or whatever other operation
ModalPoupUpExtenderID.Show()
}

This should work. Let me know if you have any other questions.
