Hi,

I am trying to use the MouseDown and MouseUp events to reduce the number of data points plotted when rotating. I'm following the example in http://www.teechart.net/support/viewtop ... eUp#p45733. The problem I encountered is that the MouseUp event is not triggered when the rotate tool is selected.

My code:

Code: Select all

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            tChart1.MouseDown += new MouseEventHandler(tChart1_MouseDown);
            tChart1.MouseUp += new MouseEventHandler(tChart1_MouseUp);
        }

        private void tChart1_MouseDown(object sender, MouseEventArgs e)
        {
            Console.WriteLine("MouseDown");
        }

        private void tChart1_MouseUp(object sender, MouseEventArgs e)
        {
            Console.WriteLine("MouseUp");
        }
    }

I'm using TeeChart .NET 2010, Visual Studio 2010 running on Windows XP, compiling for target framework ".NET Framework 4".

Is there anyone who can help me solve this problem?

With kind regards,

Hello Paul,

I have modified your code:

Code: Select all

        public Form1()
        {
            InitializeComponent();

            tChart1.MouseDown += new MouseEventHandler(tChart1_MouseDown);
            tChart1.MouseUp += new MouseEventHandler(tChart1_MouseUp);
            Steema.TeeChart.Tools.Rotate rot = new Steema.TeeChart.Tools.Rotate(tChart1.Chart);

        }
        private void tChart1_MouseDown(object sender, MouseEventArgs e)
        {
            Console.WriteLine("MouseDown");
        }

        private void tChart1_MouseUp(object sender, MouseEventArgs e)
        {
           
                Console.WriteLine("MouseUp");
            
        }

How you can see I have added a Rotate tool in the chart and MouseDown and MouseUp events, works fine for me. Could you check if this code works as you expected?

I hope will helps.

Thanks,

Hello Sandra,

Thank you for your response. I forgot to mention that I am using a ChartController. If I click the rotate button on the ChartController and then rotate only the MouseDown event is triggered. If I remove the ChartController and use your code it does work correctly. With only the Steema.TeeChart.Tools.Rotate connected both MouseDown and MouseUp events are triggered.

However, if I use the ChartController only the MouseDown event is triggered. Here is the code I'm using:

Code: Select all

        public Form1()
        {
            InitializeComponent();

            tChart1.MouseDown += new MouseEventHandler(tChart1_MouseDown);
            tChart1.MouseUp += new MouseEventHandler(tChart1_MouseUp);

            Steema.TeeChart.ChartController controller = new Steema.TeeChart.ChartController();
            controller.Chart = this.tChart1;
            this.Controls.Add(controller);
        }

        private void tChart1_MouseDown(object sender, MouseEventArgs e)
        {
            Console.WriteLine("MouseDown");
        }

        private void tChart1_MouseUp(object sender, MouseEventArgs e)
        {
            Console.WriteLine("MouseUp");
        }

Any help is appreciated.

With kind regards,
