RAD Alerts
To convert the standard Javascript Alerts to the fancy RAD Alerts add this script within the <Head> tag.<script type="text/javascript">
window.alert = function(string)
{
radalert(string.replace(/-/g, "<br />•"), "auto", null, "Alert");
}
</script>
Add the RadWindowManager in the page and configure it with the appropriate Telerik Skin.
<telerik:RadWindowManager runat="server"
ID="alertWindowManager"
Skin="Default"
AutoSize="true"
Animation="None" />
