How to make tooltips never leave until mouse move out

[mks-ydi]

Currently we can use AutoPopDelay to set the time that tooltips will stay. Is it possible to tooltips never leave until mouse move out ?

Thank you very much.

Hello mks-ydi,


For the moment is not possible to use AutoPopDelay to set the time that tooltips will stay, why I recomended than you use Annotation tools.
You can use annotation tools, with events ClickSeries or MouseMove.

You can use this code for exemple:

Code: Select all

        private void tChart1_MouseMove(object sender, MouseEventArgs e)
        {
            int index = bar1.Clicked(e.X, e.Y);
           
            if (index != -1)
            {
                anotation1.Active = true;
                anotation1.Text = bar1.YValues[index].ToString();
                anotation1.Left = e.X;
                anotation1.Top = e.Y - anotation1.Height;
            }
            else
            {
                anotation1.Active = false;
            }
            
        }

I hope than my help is usefull for you.

Hello Sandra Pazos,
Your reply really help us. Thank you very much. But annotation has a problem. We usually put the chart in a container, and sometimes the annotation can not be totally displayed，hidden by the border and its outside region of the container. I mean it is not always on top as tooltips does. How can we do this?

Hello mks-ydi,

We have found a way for your problem. You have used a very simple tooltip in the MouseEvent or SeriesClick, as you will see on next exemple:

Code: Select all

        private void tChart1_MouseMove(object sender, MouseEventArgs e)
        {
            int index = bar1.Clicked(e.X, e.Y);

            if (index != -1)
            {
                string tmpText = bar1.YValues[index].ToString();

                if (tChart1.Chart.ToolTip.Text != tmpText)
                {
                    tChart1.Chart.ToolTip.Text = tmpText;
                    tChart1.Chart.ToolTip.Show();
                }
            }
            else
            {
                tChart1.Chart.ToolTip.Hide();
            }
        }

I hope than this code help you.
