Answer 1

If you're using an ASP.Net control like a Button, you can add the following attribute to give the user a JavaScript popup before the postback actually happens:

<asp:Button runat="server" ID="Button1" OnClick="Button1_Click" OnClientClick="return confirm('Are you sure you want to do this?');" />

You can also set this property on the button object in your code:

Button1.OnClientClick = "return confirm('Are you sure you want to do this?');";
