Validation without binding

Can you use a validator class without binding, expressing the default
content as a literal?

Something like:

<TextBox HorizontalAlignment="Left" VerticalAlignment="Center"
x:Name="myText" TextWrapping="Wrap" Width="80">
<TextBox.Text>
<Binding>
<Binding.ValidationRules>
<local:NumRule Min="1" Max="1000" />
</Binding.ValidationRules>
</Binding>
</TextBox.Text>
</TextBox>

(this doesn't run, needs Bind Path="someproperty"). How would I specify the
default value?

Thanks,

John

I don't think you can apply validations without a full binding because
the data is validated as part of the transfer. However, you can bind
it to some internal object that you don't care about - something like
this:

<TextBox>
<TextBox.Resources><TextBlock x:Key="tb" /></TextBox.Resources>
<TextBox.Text>
<Binding Source="{StaticResource tb}" Path="Text">
<Binding.ValidationRules>
<local:NumRule Min="1" Max="1000" />
</Binding.ValidationRules>
</Binding>
</TextBox.Text>
</TextBox>

Hope that helps,
