    I have a user control that contains a RadDataForm and a button.

    The button is bound to a custom command that has xxx_CanExecute() and xxx_Executed() methods defined.

    I want xxx_CanExecute() to set e.CanExecute to false, if the form has any validation errors.  I'm getting the user control passed as sender, and from that I can get a reference to the RadDataForm.  But I can't for the life of me figure out how to tell if the form has any validation errors.  In the debugger I can see a validationErrors collection on the form, but that seems to be private. ValidateItem() always returns true, regardless.

    Seems to me that I'm missing something simple.  Can someone point me in the right direction?

    Hi Jaffrey,

    You can try getting access to the ValidationSummary of RadDataForm and work with its HasErrors property.
    For example: 

    var hasErrors = this.DataForm1.ValidationSummary.HasErrors;
     
    Will that approach be suitable for your scenario ? 

    Kind regards,

    That looks like what I was looking for.  Thanks.

    I'm not sure whether it's a bug, or but ValidationSummary.HasErrors always seems to be false.

    I made a simple test page, and I'm seeing ValidationSummary.Errors.Count() increment, when I type invalid content into a textbox, and I'm seeing the validation error display at the bottom of the form, but HasErrors is still false.

    Still, "Errors.Count() > 0" will work for my purposes.
