    I have the following XAML and I want the error tooltip to show when I throw and exception from the ViewModel property CobDate.

    It will show the error tool tip when the CobDate is invalid text, e.g. 'aaaasss' but when it is a valid date but greater then the SelectableDateEnd it will not show the error tool tip when I throw an exception from the ViewModel, it does highlight the textbox of the control with a red border but I want the error tooltip to show as well.

    How can I get the error tooltip to show?

    <telerik:RadDatePicker DisplayFormat ="Long"
              SelectableDateStart="{Binding MinDate, Mode=OneWay}"
              SelectableDateEnd="{Binding MaxDate, Mode=OneWay}"
              BlackoutDates="{Binding DisabledDates, Mode=OneWay}"
              ErrorTooltipContent="Invalid Date!"
                       <Binding Path="CobDate"
                               <ExceptionValidationRule />

    Hi Ollie,

    I am afraid that we do not have Validation ToolTip for RadDatePicker or any other RadControl for WPF - it is available only for Silverlight.
    We're following the standard WPF controls behavior which do not provide validation tooltip as well.

    We're sorry for any inconvenience caused.
