Changing the Legend ItemMarker

[Brian Favell]

I'm not sure if this is the correct terminology, but I think it's the Legend ItemMarker that I want.  It's the symbol in the legend whether it's a squars, circle, triangle,etc that I want to change the color of programatically.  How do I programatically change the fill color and border of these objects?

The following line of code provides an index out of range error message.
RadChart1.Chart.Legend.Items(0).Appearance.FillStyle.MainColor = Drawing.Color.FromArgb(155, 155, 155)

 

 

 

Thanks,

Brian

Hi Brian,

You should subscribe to the BeforeLayout event of the chart to be able to change anything relating Legend Item Markers. Then you can easily set Border for your Markers or Color by looping through them like this:

Protected Sub RadChart1_BeforeLayout(sender As Object, e As EventArgs)
    For i As Integer = 0 To RadChart1.Legend.Items.Count - 1
        RadChart1.Legend.Items(i).Marker.Appearance.FillStyle.MainColor = Color.Red
        RadChart1.Legend.Items(i).Marker.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Solid
        RadChart1.Legend.Items(i).Marker.Appearance.Border.Color = Color.Silver
        RadChart1.Legend.Items(i).Marker.Appearance.Border.Width = 1
    Next
End Sub
