>Re-activating form selects whole grid TextBox contents. How to change this that grid TextBox restores its old selection state and cursor position (not selected or part of text selected) ?

I'd say that you might want to have a subclass of the DataGridViewTextBoxColumn that keeps track of that information and re-sets it when it's activated ... just off the top of my head, but will that do it for you?
