Word under cursor

[Kyle]

I'm starting to play around with the Telerik RTB and I was wondering if there was a way to get the word under the mouse cursor?

Hello Kyle,

You can obtain the word at a document position using the GetCurrentWord() method. To get the DocumentPosition corresponding to the mouse position at the moment, you can use the GetDocumentPositionFromViewPoint() method. Here is a simple example:

private void RadRichTextBox_MouseRightButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    DocumentPosition position = this.radRichTextBox.ActiveEditorPresenter.GetDocumentPositionFromViewPoint(e.GetPosition(this.radRichTextBox));
    string word = position.GetCurrentWord();
}

And if you would like to directly work with the position of the document caret, you can use it like this:

string word = this.radRichTextBox.Document.CaretPosition.GetCurrentWord();

Hope this helps.

Regards,
