In the next example, I've re-used the data bound Combo Box example, but added some buttons for controlling the selection.

I've also used the Selection Changed event to capture when the selected item is changed, either by code or by the user, and act on it.

In the fourth and last event handler, I respond to the selected item being changed.

When that happens, I read the selected color (once again using Reflection, as described above) and then use the selected color to create a new background brush for the Window. If you're working with an editable Combo Box (Is Editable property set to true), you can read the Text property to know the value the user has entered or selected.

It might be an idea for you to take a look at the Difference between Selected Item, Selected Value and Selected Value Path post here for an explanation of these properties.

Try this: As I can't see all of your code, I cannot tell you what you are doing wrong.

Using WPF data binding and a custom template, we can easily render a list of colors, including a preview of the color: It's actually quite simple: In the Code-behind, I obtain a list of all the colors using a Reflection based approach with the Colors class.

The approach I went with uses a Collection View which is a class included with .

NET that encapsulates a list and the concept of a current item as well as supporting the INotify Property Changed interface. I set the Is Sychronized With Current Item to true to allow us to track the current item on the Items Source.

I assign it to the Items Source property of the Combo Box, which then renders each color using the template I have defined in the XAML part.

Each item, as defined by the Item Template, consists of a Stack Panel with a Rectangle and a Text Block, each bound to the color value.

I’m not sure yet whether using Collection View is a better approach than the alternatives I have seen which bind the Selected Value or Selected Item property.
