I have heard that it's possible to have the tools tips function of a control to show the textual contents of the control over which it hovers. For instance if the cursor hovers over the txt box for LastName the tooltips would show the last name when it kicks in. How can this be done?

What I want to do actually, if possible is to hover over a cell in a DataGrid and have the tool tip dispay the contents of that particular cell.
