Question

I have this code:

<ribbon:Button Label="Hello" />

I wanted to bind its tooltip to Label like:

<ribbon:Button Label="Hello" ToolTip="Hello" />

I have already tried creating style with the following info, but failed:

<Style TargetType="{x:Type ribbon:Button}">
            <Setter Property="ToolTip" Value="{Binding Text}" />
</Style>

Please tell me how can I fix this. Instead of ribbon:Button, normal button code be used and I want to bind its tooltip property with its Content property.

Edit: One more thing after trying, if i set the Value property of Setter inside style without any binding, it works fine. Eg:

<Style TargetType="{x:Type ribbon:Button}">
            <Setter Property="ToolTip" Value="This will show" />
</Style>

But binding is not applied here. So problem arises only when binding is done 🙁

Answer 1

Of course your style won’t work, because you always bind to the properties of your DataContext, which i doubt is your Control itself.

<Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=Text}"/>

should work fine.
