Question

Answer 1

If this is a Windows Forms TextBoxBase , you can use SelectionStart .

If you're dealing with WPF or Silverlight, there is unfortunately no direct way to handle this from the base class, as the selection information is handled by the derived classes, as different classes handle it very differently.

For example, TextBox.SelectionStart would give you the appropriate point for a TextBox , but if you had a RichTextBox , you'd need to look at the Selection . Start property explicitly, as it's handled in a separate class.
