    My company is using RadControls for WPF Q1 2010 SP2. I am extending the RadDatePicker control to add certain behaviors that are used by our FSP suite of programs. We are using Visual Studio 2008 and C#.

    When an invalid date is typed into the input box of a RadDatePicker (for example, 13/35/2011), its native behavior is to clear the field. I need to override this behavior to keep (not clear) the invalid input and set an error message property in our extended control. Is this possible and if so, how do I do that? I am not very experienced at how to code event handlers so if you could provide the code for how to hook the event and the skeleton of the new event handler, I would appreciate it.

    Would this technique work for the RadTimePicker as well? I need to do the same thing to it.

    Hi Mike,

    I am sorry, but the RadDatePicker does not support custom parsing in this version. In Q2 2010 we introduced a new control - RadDateTimePicker. It supports custom parsing as explained in this help article. You can also check out its online demos for more examples.

    Hope this information helps.

    Best wishes,
