WPF UserControl Style results in error message

Question

Hi

I'm new in WPF so I try to create a WPF UserControl. My problem is about the style of the user control I've Created. On a design time I got this error message

Can only base on a Style with target type that is base type 'RichTextBox'.

And at a run time An error Message type XamlParseException Occurs and the message is:

Cannot create instance of 'RichTextBox' defined in assembly 'PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Can only base on a Style with target type that is base type 'RichTextBox'. Error at object 'System.Windows.Controls.Grid' in markup file 'NameSpace;component/usercontrols /myusercontrol.xaml' Line 125 Position 14.

My user control have 3 richtextboxes 1 textbox and 3 dropdownlist and about 10 buttons. I think The problem is about to define the style of my user control, can anyone help me to do this.

Thanks

Answer 1

It use some style created. And What I don't Understand is when I Use it in a single window independent Project it works well. But in the project I need to use It doesn't work.

The project uses also RibbonWindow, It doesn't work nor in a classic WPF Window in the concerned project.

Here's the Xaml Code
