Putting a custom control in a resource file

Question

5.00/5 (1 vote)

See more:

I created a control that is a simple class derived from a ToggleButton that controls the color of the Background and Foreground depending on values of the DataContext. It works find when directly used, but I get an exception when this is used in an XML resource dictionary:

Cannot create unknown type '{clr-namespace:Fox.UI.Module.OutlookBarTool.Controls}BrokerColorToggleButton'.

I was trying previously to use a behaviour for the same, but also got a similar error. Any ideas?

Solution 1

this one says that you might use incorrect Build Action

The ResourceDictionary works fine for other styles, that includes ToggleButton, so very unlikely that is the problem

what BuildAction you use for this ResourceDictionary? We always use Page in WPF projects. I don't remember why exactly, apparently there were problems with other BuildActions.

That worked. Thanks. May fix some other issues I have had with using resources.
