How to assign a dynamic resource style in code?

Question

I want to produce in code the equivalent of this in XAML:

<TextBlock Text="Title:" Width="{Binding FormLabelColumnWidth}" Style="{DynamicResource FormLabelStyle}"/> 

I can do the text and the width, but how do I assign the dynamic resource to the style:

TextBlock tb = new TextBlock();             tb.Text = "Title:";             tb.Width = FormLabelColumnWidth;             tb.Style = ??? 

Answer 1

You should use FrameworkElement.SetResourceReference if you want true DynamicResource behaviour - ie updating of the target element when the resource changes.

tb.SetResourceReference(Control.StyleProperty, "FormLabelStyle") 

Answer 2

You can try:

tb.Style = (Style)FindResource("FormLabelStyle"); 

Enjoy!
