Currently the only way to define the time interval in which the Notifications show is to set the ShowInterval property which takes the interval in millisecond. But if we need a notification to run on a particular time of day like at 21:47:29, there is no way to set it. And i don't see a work around for it too, other than calculate 24 hours in milliseconds and assuming it to run at that particular time.

It would really help if we can have a notificationRunType = {Interval, Time} which could evoke either the ShowInterval or ShowTime property, so that when notificationRunType="Time" and ShowTime="21:47:29" would set the RadNotifications to run on that particular time.

Adding big text content in the Notification's Text property overflows the height of the controls wrapper:

A possible workaround is to set the height of the content wrapper manually:
        div.rnContentWrapper {
            height: 95px !important;
        }


Steps to reproduce:
        <telerik:RadNotification ID="RNRappel" runat="server" Width="500px" Height="150px" EnableViewState="false" AutoCloseDelay="0" RenderMode="Lightweight"
            CloseButtonToolTip="Fermer" ContentScrolling="Auto" VisibleOnPageLoad="true" Position="Center" ContentIcon="warning">
        </telerik:RadNotification>

    protected void Page_Load(object sender, EventArgs e)
    {
        RNRappel.Text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.";
    }

This would be usefull especially when calling the client side "Update" function of the radnotification. Currently, custom validators are getting fired when the callback occurs.
