        </i:Interaction.Triggers>
    </Button>
</DataTemplate>

Hi all,

Above I have a data template which is switching on certain data type using a data template. I am using the mvvm pattern. I want to be to bind to the ImageClick property.

I was able to do this before, but since I have moved the button inside the data template I am unable to bind to that property.

I think I need to use Relative source for the binding but am really unsure how to do it.

Help on this would be amazing.

Thanks.

You may try the below.

<Button Command="{Binding RelativeSource={RelativeSource AncestorType={x:Type YourViewModel}}, Path=DataContext.ImageClick}" />

I think it would help you..
