need help - IWindowsFormsEditorService in WPF? or possible another alternative solution to my issue

I've taken the following code and extended it to my code:

http://www.codeproject.com/KB/vb/PropertyGridEx.aspx

My code is a program written in WPF while the example is in Windows Forms Application

My code-

My problem-

the "IWindowsFormsEditorService" is only for UserControl windows that made by Windows Forms Applica开发者_开发百科tion so the following row:

wfes.DropDownControl(ucUseValue);

Shows the following errors:

Error 1 The best overloaded method match for 'System.Windows.Forms.Design.IWindowsFormsEditorService.DropDownControl(System.Windows.Forms.Control)' has some invalid arguments

Error 2 Argument 1: cannot convert from 'Visual_Command_Line.UserControls.ArgumentEditor.UseValueArg' to 'System.Windows.Forms.Control'

So, i thought of two Solutions - tell me if one of them is possible:

1. Is there any alternative to "IWindowsFormsEditorService" in WPF?

2. Is there any possible way to convert my UserControl which is "UseValueArg" to a System.Windows.Forms.UserControl type of UserControl?

3. Creating a UserControl that is of type System.Windows.Forms.Control and not of WPF (something which I already tried and it works, though it's seems stupid to have Windows Forms Application in a WPF)

Thanks in advanced, Din
