Using WPF SpellChecker in Winform App

[Patrick]

Due to some limitations and issues with the Winform version of RadSpellChecker I started investigating using the WPF version instead through an ElementHost. 
I discovered that I didn't need the ElementHost and that I could get the WPF RadSpellChecker to take my text and "pop up" by doing the following:

• Added Reference to "Telerik.Windows.Documents.Proofing"
• Added Using of "Telerik.Windows.Controls"
• Created WPF Textbox like so --> var txtControl = new System.Windows.Controls.TextBox();
• Assigned some test text to it --> txtControl.Text = "This isn't speelt rite.";
• Ran the static Check() method --> RadSpellChecker.Check(txtControl, SpellCheckingMode.AllAtOnce);

This almost works, I get the SpellCheck window with my text in it but there aren't any words in the dictionary.  Because of the way I'm doing it would I need to add the base English Dictionary back in?  Am I making some other rookie mistake?  Attached is an image of what I am seeing and below is the simple code snippet in it's entirety.

var txtControl=new System.Windows.Controls.TextBox();
txtControl.Text="This isn't speelt rite.";
RadSpellChecker.Check(txtControl, SpellCheckingMode.AllAtOnce);

P.S. I didn't know if this belonged in the Winform or WPF forum, sorry.

Hi Patrick,

The dictionaries that RadSpellChecker uses are separated from the implementation of the control. An En-US dictionary is distributed with RadControls for WPF, but it is in a different assembly than the spell checker and you should add a reference to the Telerik.Windows.Documents.Proofing.Dictionaries.En-US assembly.

You can read more about multi-language support and loading dictionaries for spell checking here.
