Tool Tip Image on grid row
posted
I want to associate a tooltip with an image to a row in a grid.  I have added a ultratooltip manager to the grid and am trying

ultraToolTipManager1.SetUltraToolTip(e.Row.GetUserUI().Control, new Infragistics.Win.UltraWinToolTip.UltraToolTipInfo(@"TEXT<img style=""width:16px; height:16px;"" data=""" + imageAsText + @"""/>", Infragistics.Win.ToolTipImage.None, "Test Data", Infragistics.Win.DefaultableBoolean.True))

 in the OnInitializeRow event.  However I am getting an "e.Row.GetUIElement()' is null" error.

Thanks for any info in advance,

Tom
