    I've run into a problem with the RadDataForm where I cannot seem to get the Cancel button to become enabled.

    The problem exists in a much more complicated app, but I created a small test app to see if I could get it to work in a very simple implementation, however it still does not.

            <local:ViewModel x:Key="vm"/>

        <Grid x:Name="LayoutRoot" Background="White" DataContext="{StaticResource vm}">
            <telerik:RadDataForm ItemsSource="{Binding Data}"/>

    Data is an Observable collection defined in the ViewModel. Data is of Type 'DataClass' . Both the ViewModel and DataClass implement INotifyPropertyChanged.

    I've looked at the demo (http://demos.telerik.com/silverlight/#DataForm/FirstLook) where it appears to work, and there doesn't seem to be anything different there from what I have above.

    Hi Wayne,

    RadDataForm's "Cancel" button is enabled only when your data type implement the IEditableObject interface. It executes the RadDataFormCommands.CancelEdit command that invokes the edited item's CancelEdit() method.
