As far as I can tell, the cotrol only handles the tool tip for a task bar in the chart. I want a tool tip for when the mouse rolls over a task in the grid on the left. I tried using the ultratooltipmanager, and I checked whether or not the element is a taskuielement and if it is then showToolTip, but I can't seem to get that to work either.

Hello clgroce,

Could you please review the sample attached to this post and see if it meets your requirements. Please feel free to let me know if I misunderstood you or if you have any other questions.

Hello clgroce,

I am checking about the progress of this issue. Please let me know If you need any further assistance on this.

Hello clgroce,

I guess I got your requirements wrong. Please try the following code:

        private void ultraGanttView1_MouseEnterElement(object sender, Infragistics.Win.UIElementEventArgs e)
        {
            if (e.Element is EditorWithTextDisplayTextUIElement && e.Element.Parent.Parent is CellUIElement)
            {
                CellUIElement cell = (CellUIElement)e.Element.Parent.Parent;
                foreach (Task task in ultraCalendarInfo1.Tasks)
                {
                    if (task.Name == cell.Row.Cells["Name"].Value.ToString())
                    {
                        currentTask = task;
                    }
                }
                EditorWithTextDisplayTextUIElement editor = (EditorWithTextDisplayTextUIElement)e.Element;
                info.ToolTipText = "CUSTOM TOOLTIP: "+currentTask.Duration.ToString(); //This is just for test
                ultraToolTipManager1.SetUltraToolTip(ultraGanttView1, info);
                ultraToolTipManager1.ShowToolTip(ultraGanttView1);
            }
            else ultraToolTipManager1.HideToolTip();
        }

 currentTask is a 'Task' object - "Task currentTask;".

Let me know if you have any questions please.

Is there no way to actually access the Infragistics.Win.UltraWinSchedule.Task object associated with a given row in the grid?

Hello clgroce,

I could modify your code as follows:

private void ultraGanttView1_MouseEnterElement(object sender, Infragistics.Win.UIElementEventArgs e)
        {
            if (e.Element is EditorWithTextDisplayTextUIElement && e.Element.Parent.Parent is CellUIElement)
            {
                CellUIElement cell = (CellUIElement)e.Element.Parent.Parent;
                EditorWithTextDisplayTextUIElement editor = (EditorWithTextDisplayTextUIElement)e.Element;
                info.ToolTipText = "CUSTOM TOOLTIP: " + cell.Row.Cells["Name"].Value.ToString();
                ultraToolTipManager1.SetUltraToolTip(ultraGanttView1, info);
                ultraToolTipManager1.ShowToolTip(ultraGanttView1);
            }
            else ultraToolTipManager1.HideToolTip();
        }
