Context menu on a line sereis of a chart

Hi,

I'm using Chart at this moment and I've got some LineSeries on the chart. Now I'm trying to respond to a user right click on one of the line series and expect a context menu pops up upon that. However, even after I set the ContextMenu property of the LineSeries, nothing is showing up. I wonder if there's anything I need to do to achieve this?

Thanks, Sean

Hi Sean,

Try setting the ContextMenu property of the line, rather than the series. This can be done by creating a custom line style, using a setter to set the ContextMenu, and then setting the style on the series.

<Style x:Key="RedPlainLineStyle" TargetType="Path">
  <Setter Property="StrokeThickness" Value="2" />
  <Setter Property="Stroke" Value="Red" />
  <Setter Property="ContextMenu">
    <Setter.Value>
      <ContextMenu>
        <MenuItem Header="Item 1" />
      </ContextMenu>
    </Setter.Value>
  </Setter>
</Style>

Set the LineStyle property on a LineSeries:

<ms:LineSeries LineStyle="{StaticResource RedPlainLineStyle}" />

I hope that helps.

Hi Jason,

Thank you for the reply. I tried the proposed solution and it worked. It was able to show the context menu. However, it conflicts with some of my other customization to the curve. I found another solution which so far behaves as what I wanted. I'm currently using the chart's context menu. It will popup when I right click on a curve as well. I can check which curve is selected and control what I want to show in the context menu. I will try using this solution for now. If it doesn't work out, I will have to modify my customization to accommodate the solution you provided.

Thanks, Sean

Hi Sean,
