How can I get celltips or tooltips to vary from cell to cell in my DataGrid
One way to do this is to use a ToolTip control and reset the control text as the mouse moves from cell to cell. Below is a derived DataGrid class that implements this idea. The main points are:
Have members that track the current hitRow and hitCol where the mouse is.
- In a MouseMove handler, do a HitTest on the mouse location to see if there is a new hit cell. If so, set the hitRow & hitCol, and hook the tooltip to hold your text according to the cell. In our sample, we just display the string value of the grid cell.
- Finally, in the MouseMove handler, after setting a new text in the tooltip, set the tooltip active so it can show itself in due time.
