RadGridView: The FreeFormDateTimeProvider is not validated correctly

When pressing Enter or Tab in the new row the ParsingDateTime event is fired after the editor is validated. Use attached to reproduce.


private void GridView_CellEditorInitialized(object sender, GridViewCellEventArgs e)
    var editor = gridView.ActiveEditor as RadDateTimeEditor;
    var editorElement = editor.EditorElement as RadDateTimeEditorElement;
    editorElement.TextBoxElement.MaskType = MaskType.FreeFormDateTime;
    var provider = ((FreeFormDateTimeProvider)editorElement.TextBoxElement.Provider);
    editorElement.TextBoxElement.Provider = new MyFreeFormDateTimeProvider(provider.Mask, provider.Culture, provider.Owner);

class MyFreeFormDateTimeProvider : FreeFormDateTimeProvider
    public MyFreeFormDateTimeProvider(string mask, CultureInfo culture, RadMaskedEditBoxElement owner) : base(mask, culture, owner)
    public override bool Validate(string stringValue)
        //do your code here
        return base.Validate(stringValue);
