Question

I have a textbox inside a style, whose text property is bound to the name property of my object here is the code:

<Style TargetType="s:Node">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ContentControl">
                <TextBox x:Name="textboxName" Text="{Binding Source={RelativeSource TemplatedParent}, Path=Tag, Mode=TwoWay}" IsHitTestVisible="False"/> 
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Inside the constructor for node I have:

public Node()
    {
        Name = "node";
        Tag = 100;    
    }

I am not sure what I am doing wrong, any help would be appreciated.

Answer 1

Source does not process a RelativeSource the way the Binding does when set as Binding.RelativeSource but just takes that markup extension object and looks for properties on it.

A RelativeSource describes how a relative source should be found and should hence not be used directly as the Source for a binding.
