WPF Validating unbound textbox

binding, textbox, validation, wpf

is it possible to use validation without the Binding part? The thing is my textbox is not bound to any object, but I still want to validate it's content. The only way I've found so far is this:

    <TextBox Grid.Row="0" Grid.Column="1" MaxLength="50" x:Name="textBoxTubeName" Margin="5,5,0,5">        <TextBox.Text>            <Binding Path="Name" UpdateSourceTrigger="PropertyChanged" Mode="TwoWay" NotifyOnValidationError="True">                <Binding.ValidationRules>                    <validation:InvalidCharactersRule />                </Binding.ValidationRules>            </Binding>        </TextBox.Text>    </TextBox>

But again, it only works when the TextBox.Text is bound to something (in this case, the Name property), how would I go about this without binding?

Thanks!

According to the MSDN forums it's not possible yet but it is planned (Note: this is an old post). However, I still can't find a way to do it so it may not be implemented yet.
