HI,

 Each Cell in the WinGrid has a ToolTipText.

 You can set this property in the WinGrids InitializeRow event.

 Here is a code snippet:

   private void ultraGrid1_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e)
        {
            int id = (int) e.Row.Cells[0].Value;
            switch (id)
            {
                case 1:
                    {
                      e.Row.Cells[0].ToolTipText = "big boss " + id;
                      break;
                    }
                case 2:
                    {
                        e.Row.Cells[0].ToolTipText = "2nd banana " + id;
                        break;
                    }

                default:
                    {
                        e.Row.Cells[0].ToolTipText = "every body else " + id;
                        break;

                    }
            }

Hi,

In my scenario I am creating ValueBasedAppearences at runtime.

Just FYI - ValueBasedAppearances are really useful if you want to set up appearances at design-time. But at run-time, they are actually a lot more work and a lot more code than you need. It's much simpler to just color the cells/rows inside the InitializeRow event of the grid.

Anyway, there's no way to base a tooltip on the ValueBasedAppearance directly. You could, of course, display a tooltip based on the value of the cell, which is essentially the same thing. There are a number of ways to do this. One way would be to assign a ToolTip to the grid control based on the current location of the mouse in the MouseMove or MouseDown event.To determine which cell the mouse is over, you can use UIElements. Here's an article that shows you how to do it.
