I cannot set a Hand Cursor for an automatic LegendItem. Is this possible?

I tried this approach (the changing of the Font to an underlined Font works):

 
  private void ChartControl_MouseMove(object sender, MouseEventArgs e)
   {
    NHitTestResult res = null;

    try
    {
      res = HitTest(e.X, e.Y);
    }
    catch (Exception)
    {

    }

    if (null != res)
    {
      if (res.ChartElement == ChartElement.LegendDataItem)
      {
       for (int i = 0; i < Charts.Count; i++)
       {
        foreach (NSeriesBase s in Charts[i].Series)
        {
          NSeriesLegend seriesLegend = s.Legend;
          seriesLegend.TextStyle.FontStyle.Style = FontStyle.Regular;
        }
       }

       res.LegendDataItem.TextStyle.FontStyle.Style = FontStyle.Underline;

       res.LegendDataItem.InteractivityStyle.Cursor.Type = CursorType.Hand;

       resetLegend = true;

       Refresh();
      }
      else
      {
       if (resetLegend)
       {
        for (int i = 0; i < Charts.Count; i++)
        {
          foreach (NSeriesBase s in Charts[i].Series)
          {
           NSeriesLegend seriesLegend = s.Legend;
           seriesLegend.TextStyle.FontStyle.Style = FontStyle.Regular;
          }
        }

        Refresh();
        resetLegend = false;
       }
      }
    }
   }

Hi Alexander,

Generally, you should not modify the attributes of automatically generated legend items, because in the general case they are clones of series legend attributes. Instead, you can simply create a legend with custom items. You can check out the Panels \ Legend \ Custom Legend Items example on how to generate custom legend items. 

We hope this helps - let us know if you have any questions.


Best Regards,
