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?
