ColWidths and CellTips

I''d like to display a tooltip when a user hovers over a cell and the contents of the cell is wider than the width of the column. In QueryCellInfo I am setting the CellTipText. How do I determine if the size of text in that cell is wider than the column width? What performance cost does this add?

Here is a forum thread that discusses using Tooltips to handle this problem. http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=5449 Make sure you click the little disk icons to get the samples. They might be scrolled off the screen to the right.
