I have a .NET PropertyGrid that (amongst other things) display a property with the validation rule:
[IntegerValidator(MinValue = 1, MaxValue = 5)]
If the user attempts to set it to a value outside the range then I would expect a "Properties Window" dialog with the message "Property value is not valid" and a Details button that allows the dialog to be expanded to display the message:
"The value for the property 'XXXX' is not valid. The error is: The value must be inside the range 1-5."
Occasionally though I just get an exception that is caught at the top level by my application (which then terminates).
Any ideas why this should happen? (It does seem to happen when, on leaving the cell, the user immediately scrolls the grid - but not always.)
