How can I get toolbox icon of standard WPF control at runtime?

Question

I tried something like this:

var attrs = typeof(System.Windows.Controls.ComboBox).GetCustomAttributes(typeof(System.Drawing.ToolboxBitmapAttribute), true);

...but attrs is empty collection. I also tried to look up for icons resources in assemblies and nothing found.

Answer 1

That's because the ComboBox class is the actual run-time class, which has no such attributes. You'll need to find the design-time class. I've briefly looked through some of the WPF assemblies but couldn't find it.
