Task ID in ToolTipTextNeeded

[konrad]

I need to show something different that Text in ToolTip.

How to get other property like Id, Start, End etc (binded row)... connected with GanttViewTaskElement?

 

private void GanttView_ToolTipTextNeeded(object sender, ToolTipTextNeededEventArgs e)
{
  if(sender.GetType() == typeof(Telerik.WinControls.UI.GanttViewTaskElement))
  {
    var task = (Telerik.WinControls.UI.GanttViewTaskElement)sender;
    //e.ToolTipText = task.Id.Text.ToString();
  }
}

Hello Dominik,

Thank you for writing.

In order to achieve the desired result, you would need to work with the parent item element keeping reference to the data object: 

private void radGanttView1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
    GanttViewTaskElement taskElement = sender as GanttViewTaskElement;
    if (taskElement != null)
    {
        GanttGraphicalViewBaseItemElement itemElement = taskElement.Parent as GanttGraphicalViewBaseItemElement;
        if (itemElement != null)
        {
            e.ToolTipText = itemElement.Data.Index + " | " + itemElement.Data.Start.ToShortDateString() +
                " | " + itemElement.Data.Title + " | " + itemElement.Data.End.ToShortDateString();
        }

    }
}

I hope this helps. Should you have  further questions please do not hesitate to write back.
