ToolTips on WPF Alpha

[ITUser]

Using the following code:

Code: Select all

            
            Chart tChart = new Chart();
            tChart.ToolTip = new ToolTip { Content = "This tooltip does not show but should" };

When you mouse over the chart or a line or anything I do not get the tooltip poping up.

Is there a setting that I could be possibly missing?

Also would it not make some sense to attach tooltips per line instead of at the chart level. I noticed that Line and FastLine do not have a .ToolTip property.

Hello Michael,

No, I'm afraid TooTips were non-functional in the alpha version. This has since been improved.

Christopher,

So I am now playing around in the beta and I am still struggling with tooltips. I can get them to fire and display but not 100% of the time. It is sort of a random thing if the tooltip will actual display the data or not. Also I have noticed that once the tooltip is fired it just sticks there and so if I move to another line to pick up and display that lines data the tooltip just sticks in the old location. It used to move again to the location of the cursor when the new mouse over was fired.

Why doesn't the line control itself have a tooltip instead of the chart? Because it seems to be a slight problem when I have to attach the tooltip to the chart and then change the data inside of it each time I mouse over a line.

Is there another way that is recommended to do this sort of thing? I basically have taken ideas from our previous code base using TeeChart .Net and ported the ideas but it seems the ToolTip is the only thing I cannot get working correctly.

Hi Michael,

Yes, we are aware of that. This is strange but after a little while MarksTip tool stops working. When you move the mouse out of the window and enter it again it starts working again. We don't know which is the cause of this problem. In the meantime, we recommend you to use Annotation tools instead, for example:

Code: Select all

		public Window1()
		{
			InitializeComponent();
			InitializeChart();
		}

		private void InitializeChart()
		{
			Steema.TeeChart.Styles.Points points1 = new Steema.TeeChart.Styles.Points(tChart1.Chart);
			points1.FillSampleValues();

			//Steema.TeeChart.Tools.MarksTip mt1 = new Steema.TeeChart.Tools.MarksTip(tChart1.Chart);
			//mt1.Series = points1;
			//mt1.MouseAction = Steema.TeeChart.Tools.MarksTipMouseAction.Move;

			tChart1.MouseMove += new MouseEventHandler(tChart1_MouseMove);
		}

		void tChart1_MouseMove(object sender, MouseEventArgs e)
		{
			foreach (Steema.TeeChart.Styles.Series s in tChart1.Series)
			{
				Point p = e.GetPosition(tChart1.Chart.Parent.GetControl());
				int index = s.Clicked(p);

				tChart1.Tools.Clear();

				if (index != -1)
				{
					Steema.TeeChart.Tools.Annotation anno1 = new Steema.TeeChart.Tools.Annotation(tChart1.Chart);

					anno1.Text = s.YValues[index].ToString();
					anno1.Shape.CustomPosition = true;
					anno1.Shape.Left = p.X;
					anno1.Shape.Top = p.Y;
				} 
			}			
		}
