DataForm and IDataErrorInfo

[Armin]

Hello,
is it in some way possible that RadDataForm uses the IDataErrorInfo interface to validate user input and to show the according error messages?

Hello Armin,

I have prepared an exaple project that illustrates such a scenario. I am attaching it for your reference.

Do you have an example solution for RadDataForm and IDataErrorInfo in WPF?  I cannot get the errors to display.  Works with RadGridView but not RadDataForm. The "public string this[string columnName]" get is never called when the collection is attached to the RadDataForm.

Nevermind.  It does work in WPF.  Needed the binding to be setup like:

{Binding Name, Mode=TwoWay, ValidatesOnExceptions=True, NotifyOnValidationError=True, ValidatesOnDataErrors=True}

Was missing the ValidatesOnDataErrors.  This is not mentioned in the documentation.  Thanks.
