Can I Rebind Chart with asynchronous way?

[yiwei]

Hi,

I have a method that use asynchronous way.

I want to update the PaletteBrushes when some data has already been prepared.

But the PaletteBrushes doesn't updated after i invoke the  asynchronous method.

Is there any way to meet my requirement?

Thanks

Hello Yiwei,

You can rebind the chart to handle this scenario. This may look something like this:

public CurrentIssue()
      {
          InitializeComponent();

          RadChart.ItemsSource = new int[] {123, 4, 5, 6, 7, 78};

          DispatcherTimer timer = new DispatcherTimer();
          timer.Interval = new TimeSpan(0, 0, 3);
          timer.Start();
          timer.Tick += new EventHandler(timer_Tick);
      }

      void timer_Tick(object sender, EventArgs e)
      {
          RadChart.PaletteBrushes.Clear();
          RadChart.PaletteBrushes.Add(new SolidColorBrush(Colors.Red));
          RadChart.Rebind();
          (sender as DispatcherTimer).Stop();
      }

I hope this information helps.

Best wishes,
