The easy one to use is the one that works right out of the box: System.Windows.Forms.RichTextBox. The one I need to use is System.Windows.Controls.RichTextBox.

I have a System.Windows.Forms.RichTextBox in my program, but need to convert it to a System.Windows.Controls.RichTextBox because it has the ability to do spell check (http://rdsrc.us/pWeOTh).

I have all the references, and I can create the RichTextBox, but I cannot figure out how to actually get it on the form.

 
Dim x As New RichTextBox
        x.SpellCheck.IsEnabled = True
        x.Width = 200
        x.Height = 200
        x.Visibility = Visibility.Visible

Open in new window


How do I get this new RTB on the form so I can use it?

Add it to a container.  =)

The Form:

    Me.Controls.Add(x)

A Panel:

    Panel1.Controls.Add(x)

Etc....

Idle_Mind:

Tried me.controls.add(), it is the wrong type:
Error      1      Value of type 'System.Windows.Controls.RichTextBox' cannot be converted to 'System.Windows.Forms.Control'.      C:\Users\michael\Documents\Visual Studio 2010\Projects\ComposerPad\ComposerPad\Form1.vb      112      25      ComposerPad

lcoation doesn't work either:
Error      1      'location' is not a member of 'System.Windows.Controls.RichTextBox'.      C:\Users\michael\Documents\Visual Studio 2010\Projects\ComposerPad\ComposerPad\Form1.vb      112      9      ComposerPad

Ah!...sorry.  I wasn't paying attention very closely.

The System.Windows.Controls.RichTextBox is a WPF control.  It can't be used in a WinForms app.  If you really need that control then build a WPF application.

*WinForms and WPF applications are completely different beasts!  =\

Oh crap.

Does that mean I have to RE-BUILD the ENTIRE application as a WPF application?

Can I copy / paste the controls from one to the other?

Is this a major undertaking?

Major would be an understatement...

WPF applications use a completely different architecture and paradigm than a WinForms application!

I don't know if this is worth the effort:
