Thank you, I believe I can make this work for my requirements.

Something else that might now be able to be accomplished:  The row.description is also sometimes too long.  I'm not familiar enough with the UI hierarchy to know the elements when MouseEnterElement fires; can someone provide the code to accomplish showing the row description when entered?

 Something like the following but this doesn't always work:

         If e.Element.GetAncestor(GetType(RowUIElement)) IsNot Nothing Then
             If e.Element.GetType Is GetType(RowUIElement) Then
                ToolTipInfo.ToolTipText = DirectCast(e.Element, Infragistics.Win.UltraWinGrid.RowUIElement).Row.Description
                UltraToolTipManager1.SetUltraToolTip(UltraGrid1, ToolTipInfo)                
                 UltraToolTipManager1.ShowToolTip(UltraGrid1)             
         End If 

Thank you, this enabled me to catch appropriate elements and properly show (and not hide) for the row descriptions.

         ElseIf e.Element.GetAncestor(GetType(RowUIElement)) IsNot Nothing Then
                If e.Element.GetType Is GetType(RowAutoPreviewUIElement) Then
                             ToolTipInfo.ToolTipTitle = "Row Warnings"
                             ToolTipInfo.ToolTipText = DirectCast(e.Element, Infragistics.Win.UltraWinGrid.RowAutoPreviewUIElement).Row.Description        
                             UltraToolTipManager1.SetUltraToolTip(UltraGrid1, ToolTipInfo)
                             UltraToolTipManager1.ShowToolTip(UltraGrid1)
                 End If

I'm now having a problem where the UltraDropDown popups are showing as well (in addition to the UltraTooTipManager tips).  With this being my first use of this class, help would be appreciated again for the steps to stop showing/suppressing these ultraDropDown tooltips also.

Thanks in advance,

Eric

I was able to disable the built-in/default grid tooltips by:

ultraGrid1.DisplayLayout.Override.TipStyleCell = TipStyle.Hide

Hi, I have one query regarding the same, the default tooltip appears in grid ,only when the cell text is completly not visible. Is it possible to make the tooltip manager's behaviour also same as that of the existing Typstyle?.Because when add tooltip manager it is appearing for each and every cell even it is completely visible to read.

Hi,

The editor element in the cell keeps track of whether or not the data fits within the available space. So you would have to get the UIElement in order to determine whether or not to show the tooltip. Presumably you are changing the tooltip based on the mouse position over the grid, so you are probably using either MouseDown or MouseMove. Here's an example of how you might go about this:

        private void ultraGrid1_MouseMove(object sender, MouseEventArgs e)
        {
            var grid = (UltraGrid)sender;
            var lastElementEntered = grid.DisplayLayout.UIElement.LastElementEntered;
            if (null == lastElementEntered)
                return;

            var embeddableUIElementBase = lastElementEntered as EmbeddableUIElementBase;
            if (null == embeddableUIElementBase)
                embeddableUIElementBase = lastElementEntered.GetAncestor(typeof(EmbeddableUIElementBase)) as EmbeddableUIElementBase;

            if (null == embeddableUIElementBase)
                return;
            
            Debug.WriteLine(embeddableUIElementBase.IsDataFullyVisible);
        }

Thanks a lot Mike
