I am using an MSFlexgrid with a single textbox for editing purposes. I already have coded the ability for a user to enter values into each cell. What I need now is the ability to click on any given cell and have a blinking cursor appear at the exact position the user clicked. Then, I would like to allow the user to edit their value by selecting certain characters only (i.e. if value is 123.456, the user can choose to change just the 2 and 3) or the whole value.
