Trackball symbol capturing clicks

[Marcus johansson]

Hello,

We're capturing MouseDown events on our series. This worked well in combination with series tooltips. But we just replaced the tooltips with NearestPoint trackball information, since it's less "sensitive" than tooltips. However, the trackball symbol seems to capture the MouseDown event. So if the user clicks on the trackball symbol (which feels very natural), we don't get the MouseDown event for the series. Is there any way around this?

Best regards,

Marcus

Hi Marcus Johansson, 

 

We have analyzed your query and we have achieved your requirement by disable the IsHitTestVisible property of AdorningCanvas in ChartTrackballBehavior. Please find the following code snippet for your reference. 

 

<syncfusion:SfChart Height="500" Width="500" x:Name="chart" Loaded="chart_Loaded"> 

 

 . . . 

 

    <syncfusion:SfChart.Behaviors> 

        <syncfusion:ChartTrackBallBehavior x:Name="trackball"/> 

    </syncfusion:SfChart.Behaviors> 

 

</syncfusion:SfChart> 

 

 

private void chart_Loaded(object sender, RoutedEventArgs e) 

{ 

       trackball.AdorningCanvas.IsHitTestVisible = false; 

} 

 

Also, we have attached the sample for your reference. Please find the sample from the below link.
