Hi Steema Support,

We are working on a project which is being created in Silverlight. For this we are using Tee-Chart for .NET 2010 Silverlight version. In this project we have a map chart in which we have to display a tooltip on each portion of map. We also have some bubble series too over this map.

First of all we used Marks Tip tool to display tooltip on chart. But we faced unhandled exception when frequently move mouse inside and outside of map. To overcome this problem we are now using Annotation Tool as tooltip, and managing it programmatically on mouse move over the map. But the problem we are facing we have to bind this custom tooltip inside the map area. Means this tooltip should always be inside the map area when we move mouse over map. Please suggest any sufficient solution for the same.

Any suggestion will be highly appreciated.

Thanks & Regards

Hello Planoresearch,

I have made a simple code where I can not reproduce your problem with MarkTips:

Code: Select all

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

        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            Steema.TeeChart.Silverlight.Styles.Map map = new Steema.TeeChart.Silverlight.Styles.Map(tChart1.Chart);
            map.FillSampleValues();
            Steema.TeeChart.Silverlight.Tools.MarksTip marktip = new Steema.TeeChart.Silverlight.Tools.MarksTip(tChart1.Chart);      
        }

Previous code is made with last version of TeeChart.Net 2011. Can you check, if previous code works as you expected? If in previous code doesn't appears your problem please send us a simple example, so we can reproduce your problem exactly here.

Thanks,
