Property binding not working in Grouping mode

[sally an]

Hello

I am working with a complicated scenario with propertygrid

I am binding a chart's background property to viewmodel Background property (type of Color)

This field in propertygrid is using my custom control, and I tried to add this line in my view model class:

    [Editor("Background", typeof(ColorEditor))]

Then in window load event add this editor to my propertygrid, I get my editor in this field regardless if I add above line or not

            CustomEditor colorEditor = new CustomEditor() { HasPropertyType = true, PropertyType = typeof(Color), Editor = new ColorEditor() };

then I do get my editor in this field.

The problem is, in A-Z mode this works fine, but in Grouping mode the custom editors are not working - looks like the value of the property is not bound, string value is empty (ChartTitle field) and my custom combobox drop down selected value is empty - I do get my color combo box though)

Please advise any solution to this, thanks a lot.

Also I tried to add [Category("MyCategory")] and [Display(GroupName="MyCategory"] to my properties and grouping is still "Misc" instead of "MyCategory"

Please advise, thanks.

Thank you very much – I found the problem is I need this line as in your code 

                    TargetNullValue = new object() 

Yay!
