Hi,

Problem is that after 5 second tooltip is hidden and if i have set time 30 sec for tooltip then next ultragrid cell tooltip is not updated as per mouse move.

My Code is here:

void _Grid_MouseEnterElement(object sender, UIElementEventArgs e)   

{   

UltraGridCell cell = e.Element.GetContext(typeof(UltraGridCell)) as UltraGridCell;     

UltraToolTipInfo utti = _toolTipManager.GetUltraToolTip(m_grid);

if (cell != null)

{      

    utti.ToolTipText = cell.Text;    

}
else    

{

  utti.ToolTipText = string.Empty;    

}

}

OR

I have tried below code also;

Point prevCellPoint = Point.Empty;

void Grid_MouseMove(object sender, MouseEventArgs e)

        {

UltraGrid grid = sender as UltraGrid;

UltraToolTipManager _toolTipManager = new UltraToolTipManager();

UltraToolTipInfo utti = _toolTipManager.GetUltraToolTip(grid);         

            utti.ToolTipText =

string.Empty;

Point screenpoint = Control.MousePosition;

Point clientpoint = grid.PointToClient(screenpoint);

            Infragistics.Win.

UIElement uiElement = m_grid.DisplayLayout.UIElement.ElementFromPoint(clientpoint);

UltraGridCell cell = uiElement.GetContext(typeof(UltraGridCell)) as Infragistics.Win.UltraWinGrid.UltraGridCell;

if (cell != null)

            {              

if (prevCellPoint != clientpoint)

                {

                    utti.ToolTipText = cell.Text;

//_toolTip.SetToolTip(grid, cell.Text);

                    prevCellPoint = clientpoint;

                }         

            }

else

            {

                utti.ToolTipText =

string.Empty;

            }

        }

Please suggest
