Binding to a custom control property

Hello I have a custom control. This custom control has it's DataContext set to an entity. In my custom control I then bind some TextBlocks to various properties of this entity.

I would also like to bind a TextBlock to a property of the control's class. I do not want/need to set this property through the XAML.

Something like 

<TextBlock Content="{Binding Path=MyControl.Property}" />

Right now, my it seems to be trying to use the bound entity to resolve this binding, rather than my custom control's class.

If the TextBlock is within the ControlTemplate of your custom control then you could create a DP on your custom control and then template bind to it. e.g.

<TextBlock Text="{TemplateBinding CustomControlPropertyName}" />

You can use RelativeSource in your Binding

{Binding Path=PathToProperty, RelativeSource={RelativeSource AncestorType={x:Type MyControl}}}

In your custom control you should expose a dependency property with the property you want to bind.

Also, you probably don't want to bind the content of the textblock, you want to bind the text:

<TextBlock Text="{Binding Path=MyControl.Property}" />
