WPF(x64) tool drawline is not moved on dragging

[Eskimo17]

Hi,

the drawline is not moved on dragging on c# wpf(x64). We are using tee chart for .net (Version .NET 2013 4.1.2013.07300)
The position of the line is changed on dragging, but the line is not moved to the new position.

After selected with the mouse and dragging around, the black line isn't move at it should, but the labels start and endposition
are at the new position.

Following code shows the behavior:

XAML:

Code: Select all

<Window x:Class="WpfTestTeeChart.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

Some Suggestions ?

Hello,

Some Suggestions ?

Yes, you can use this:

Code: Select all

 public MainWindow()
    {
      //... other code ...
      MyTeeChart.MouseUp += MyTeeChart_MouseUp;
      MyTeeChart.MouseMove += MyTeeChart_MouseMove;

    }

    void MyTeeChart_MouseMove(object sender, System.Windows.Input.MouseEventArgs e)
    {
      _drawLine1.EnableDraw = true;
    }

    void MyTeeChart_MouseUp(object sender, System.Windows.Input.MouseButtonEventArgs e)
    {
      _drawLine1.EnableDraw = true;
    }

I will add similar code internally to the source code to enable this to work directly.
