Hi,
If you want to show confirmation message box for alert, then on button OnClientClick property just call one javascript function and check the confirmation message based on confirmation you can go a head or skip the process by setting return true/false.
In confirmation we get Ok/Cancel, based on selection we can set return true/false in javascript based on return statement button OnClick event will trigger, if it is true onclick event will trigger or else it won't.

<asp:Button ID="btnConfirm" runat="server" OnClick = "btnConfirm_Click" Text = "Raise Confirm" OnClientClick = "Confirm()"/>
function Confirm() {
if (confirm("Do you want to save data?")) {
return true;
} else {
return false;
}
}
