I corrected the error myself so nevermind :)

How do you recommend the usage of tooltipmanager with treenodes...?

Right now using events on the treeview to found mouseovers on the nodes and then doing the tooltipmanager.ShowToolTip(this) but showtooltip do not use the initialdelay?

You can either implement a delay yourself using a timer.

Or... instead of calling ShowToolTip, assign the tooltip to the tree using the UltraToolTipManager.GetToolTipInfo method.

If i assign it to the tree it shows tooltip when i hover the tree. I want it to show the tooltip when i hover a node and it should disappear when the cursor leaves the node...

The idea is that you would set the tooltip when the mouse is over the node and then when the mouse is not over a node, you would clear the tooltip. You could set a different tooltip for each node that way.

Hi Roopa,

If this is working for you, then I think it's fine.

I would probably start the timer after setting the tooltip, just to be safe.

Thank you Mike,

I have implemented in the following manner

private bool _toolTipDispalyed = false ;

 private void UtJobDefinitonWidgetMouseEnterElement(object sender, Infragistics.Win.UIElementEventArgs e)
        {
            if (e.Element is NodeTextUIElement)
            {
                toolTipTimer.Start();            
                var point = new Point(e.Element.Rect.X, e.Element.Rect.Y);
                UltraTreeNode node = utJobDefinitonWidget.GetNodeFromPoint(point);
                if (node != null)
                {
                    string nodeText;

                    if (node.Text == "Scheduler" || (node.Parent != null && node.Parent.Text == "Scheduler"))
                        nodeText = "Scheduling service available jobs.";
                    else
                        nodeText = "Job available for user " + (node.Parent == null ? node.Text : node.Parent.Text);

                    var tipInfo = new UltraToolTipInfo(nodeText, Infragistics.Win.ToolTipImage.Default, "", Infragistics.Win.DefaultableBoolean.True);                   
                    ultraToolTipManager1.SetUltraToolTip(utJobDefinitonWidget, tipInfo);                 
                }
            }
            else
                ultraToolTipManager1.HideToolTip();
        }

        private void ToolTipTimerTick(object sender, EventArgs e)
        {
            ultraToolTipManager1.ShowToolTip(utJobDefinitonWidget);
            _toolTipDispalyed = true;
            toolTipTimer.Stop();
        }

        private void UtJobDefinitonWidgetMouseLeaveElement(object sender, Infragistics.Win.UIElementEventArgs e)
        {
            if(!_toolTipDispalyed)
                toolTipTimer.Stop();
        }

Thank you , it works :-)
Do you suggest any changes?

Hi,

It's pretty simple. Instead of calling ShowToolTip in the code you have here, you would call the Start method on a Timer object.

In the Timer_Tick event, you call ShowToolTip. That way, the tooltip doesn't shot until the timer ticks. You will also want to stop the timer at that point.

Could you please tell me how you have achived using timer, My code as follows

  private void UtJobDefinitonWidgetMouseEnterElement(object sender, Infragistics.Win.UIElementEventArgs e)
        {
            if (e.Element is NodeTextUIElement)
            {
                var point = new Point(e.Element.Rect.X, e.Element.Rect.Y);
                UltraTreeNode node = utJobDefinitonWidget.GetNodeFromPoint(point);
                if (node != null)
                {
                    string nodeText;

                    if (node.Text == "Scheduler" || (node.Parent != null && node.Parent.Text == "Scheduler"))
                        nodeText = "Scheduling service available jobs.";
                    else
                        nodeText = "Job available for user " + (node.Parent == null ? node.Text : node.Parent.Text);

                    var tipInfo = new Infragistics.Win.UltraWinToolTip.UltraToolTipInfo(nodeText, Infragistics.Win.ToolTipImage.Default, "", Infragistics.Win.DefaultableBoolean.True);                   
                  
                    ultraToolTipManager1.ShowToolTip(utJobDefinitonWidget);
                }
            }
            else
                ultraToolTipManager1.HideToolTip();
        }

I want to provide delay before displaying the popup as it shows up immediately
