display tooltip on mouse hover in cell
posted

Hello

how is it possible to read cell value and display tooltip on mouse hover in a grid .

i tryed the

Point mousePoint = new Point(MousePosition.X, MousePosition.Y);

UIElement element = ultraGrid1.DisplayLayout.UIElement.ElementFromPoint(mousePoint);

UltraGridCell cell = element.GetContext(typeof(UltraGridCell)) as UltraGridCell;

 

if (cell != null)

{

MessageBox.Show(cell.Row.Index.ToString() + " " + cell.Column.Key);

}

 

but it does not work

    My guess is that MousePosition returns you the position of the mouse in screen coordinates, not control coordinates. You can probably convert the coords using grid.PointToClient. Or you can use the MouseMove even and use e.X and e.Y. 

    Or, you could use grid.DisplayLayout.UIElement.LastElementEntered, instead of ElementFromPoint.

    Or, you could use MouseEnterElement and MouseLeaveElement, as suggested above. :)
