The following example demonstrates how to check the spelling of a GridControl cell’s content:

1. Implement the DXSpellChecker behavior for the GridControl. Refer to the Lesson 3 - Configure Spelling Check in XAML topic for details.

2. Handle a current GridControl view‘s GridViewBase.ShownEditor event that is raised when the grid cell is activated. Retrieve the active editor and run the spell checker as shown below:

   View Example

   GridControlSpellChecker.cs

   private void CardView_ShownEditor(object sender, EditorEventArgs e)
   {
       var cardView = (sender as CardView);
       BaseEdit activeEditor = cardView.ActiveEditor;
       if (SpellChecker.SpellCheckMode == DevExpress.XtraSpellChecker.SpellCheckMode.OnDemand)
           CheckActiveEditor(activeEditor);
   }
   void CheckActiveEditor(BaseEdit activeEditor)
   {
       activeEditor.Dispatcher.BeginInvoke(new Action(() =>
       {
           if (SpellChecker.CanCheck(activeEditor))
               SpellChecker.Check(activeEditor);
       }), DispatcherPriority.Loaded);
   }
   

   GridControlSpellChecker.vb

   Private Sub CardView_ShownEditor(ByVal sender As Object, ByVal e As EditorEventArgs)
       Dim cardView = (TryCast(sender, CardView))
       Dim activeEditor As BaseEdit = cardView.ActiveEditor
       If SpellChecker.SpellCheckMode = DevExpress.XtraSpellChecker.SpellCheckMode.OnDemand Then
           CheckActiveEditor(activeEditor)
       End If
   End Sub
   Private Sub CheckActiveEditor(ByVal activeEditor As BaseEdit)
       activeEditor.Dispatcher.BeginInvoke(New Action(Sub()
           If SpellChecker.CanCheck(activeEditor) Then
               SpellChecker.Check(activeEditor)
           End If
       End Sub), DispatcherPriority.Loaded)
   End Sub
   

3. In the SpellChecker.CheckCompleteFormShowing event handler, set the Handled property to true to prevent showing The spelling check is complete dialog box when the grid control’s editor does not contain errors:

   View Example

   GridControlSpellChecker.vb

   Private Sub Checker_CheckCompleteFormShowing(ByVal sender As Object, ByVal e As DevExpress.XtraSpellChecker.FormShowingEventArgs)
       e.Handled = True
   End Sub
   

   GridControlSpellChecker.cs

   void Checker_CheckCompleteFormShowing(object sender, DevExpress.XtraSpellChecker.FormShowingEventArgs e)
   {
       e.Handled = true;
   }
   

4. As a result, the spelling form is invoked when the editor is activated. If the SpellingSettings.CheckAsYouType property is set to true, the misspelled words are highlighted.
