WPF: Adding speller to custom context menu
One of the interesting features in Editing is the speller and it works really well. :) One of the ineteresting scenarios when it comes to speller is to add the speller choices to a custom context menu. The speller choices would have to be added in the ContextMenuOpening event handler as below:
spellingError = textBox.GetSpellingError(caretIndex);
if (spellingError != null){
foreach (string str in spellingError.Suggestions) {
MenuItem mi =
new MenuItem(); mi.Header = str;
mi.FontWeight = FontWeights.Bold;
mi.Command = EditingCommands.CorrectSpellingError;
mi.CommandParameter = str;
mi.CommandTarget = textBox;
textBox.ContextMenu.Items.Insert(cmdIndex, mi);
cmdIndex++;
}
Separator separatorMenuItem1 =
new Separator(); textBox.ContextMenu.Items.Insert(cmdIndex, separatorMenuItem1);
cmdIndex++;
MenuItem ignoreAllMI =
new MenuItem(); ignoreAllMI.Header =
"Ignore All"; ignoreAllMI.Command = EditingCommands.IgnoreSpellingError;
ignoreAllMI.CommandTarget = textBox;
textBox.ContextMenu.Items.Insert(cmdIndex, ignoreAllMI);
cmdIndex++;
Separator separatorMenuItem2 =
new Separator(); textBox.ContextMenu.Items.Insert(cmdIndex, separatorMenuItem2);
}
Thats all there is to it. Its the same for RichTextBox except for the first line where you get the spellingError - rtb.GetSpellingError(rtb.CaretPosition)
The complete sample code is attached so that you can see it working in all glory :)..
