How to personalize ToolTip in TimeLine ?
posted

Hi,

I'd like to modify ToolTip information in TimeLine. Instead showing Duration I'd like to show a custom column from task. 

Is it possible ? 

I've found  event TaskToolTipDisplaying, but I can't change ToolTipText.

I create new instance of toolTip but I have to reset all value from the original e.ToolTip. 

There is a way to modify just the text without cloning with reflection the original one ?

    Hi,

    There are different approaches to solve this task, but the easiest way is through TaskToolTipDisplaying event.  Maybe you could try the code below:


    private void ultraGanttView1_TaskToolTipDisplaying(object sender, Infragistics.Win.UltraWinGanttView.TaskToolTipDisplayingEventArgs e)

            {

               ToolTipInfo info = e.ToolTipInfo;

                info.DisplayStyle = ToolTipDisplayStyle.BalloonTip;

                info.ToolTipText = "My custom information" + Environment.NewLine + "Second row of information"; //e.Task.Resources.ToString();

                info.ToolTipText += Environment.NewLine + "My start date "+ e.Task.StartDateTime.ToShortDateString();

                info.ToolTipText +=  Environment.NewLine + "My custom column data:" + e.Task.GetCustomProperty("Key of my custom column");

                e.ToolTipInfo = info;

            }

    Let me know if you have any questions.
