Question

I have a a IMultiValueConverter that dynamically creates TextBlock controls. The issue is that it has no styles.

How can I tell my new TextBlock to use a style that was defined in my XAML resource dictionary?

Answer 1

See the following question: how to use DynamicResource in the code behind?

Use SetResourceReference, it’s equivalent to use DynamicResource in Xaml

So if your Style has the Key myTextBlockStyle

TextBlock textBlock = new TextBlock();
textBlock.SetResourceReference(FrameworkElement.StyleProperty, "myTextBlockStyle");
