I have tried to do this in a few places... but perhaps this is not supported
I'd like to be able to apply HTML formatting to the LegendItem Title so that when the (Datapoint.LegendTitle) in the LabelFormatting routine causes the title to have html applied.
Private Sub LegendElement_VisualItemCreating(sender As Object, e As LegendItemElementCreatingEventArgs)e.ItemElement = New CustomLegendItemElement(e.LegendItem)
e.LegendItem.Title = "<html><span><font=Arial><Color=White><size=18>" & e.LegendItem.Title & "</span></html>"
e.ItemElement.Font = FontSegio14
End Sub

Hello, Martin,
I have prepared a sample code snippet demonstrating how to enable HTML-like text formatting for the chart legend items:
Sub New()
' This call is required by the designer.
InitializeComponent()
Dim spy As New RadControlSpyForm()
spy.Show()
AddHandler Me.RadChartView1.ChartElement.LegendElement.VisualItemCreating, AddressOf LegendElement_VisualItemCreating
Me.RadChartView1.ShowLegend = True
Me.RadChartView1.LegendTitle = "Legend"
Dim barSeries As New Telerik.WinControls.UI.BarSeries("Performance", "RepresentativeName")
barSeries.LegendTitle = "Q1"
barSeries.DataPoints.Add(New CategoricalDataPoint(177, "Harley"))
barSeries.DataPoints.Add(New CategoricalDataPoint(128, "White"))
barSeries.DataPoints.Add(New CategoricalDataPoint(143, "Smith"))
barSeries.DataPoints.Add(New CategoricalDataPoint(111, "Jones"))
barSeries.DataPoints.Add(New CategoricalDataPoint(118, "Marshall"))
Me.RadChartView1.Series.Add(barSeries)
Dim barSeries2 As New Telerik.WinControls.UI.BarSeries("Performance", "RepresentativeName")
barSeries2.LegendTitle = "Q2"
barSeries2.DataPoints.Add(New CategoricalDataPoint(153, "Harley"))
barSeries2.DataPoints.Add(New CategoricalDataPoint(141, "White"))
barSeries2.DataPoints.Add(New CategoricalDataPoint(130, "Smith"))
barSeries2.DataPoints.Add(New CategoricalDataPoint(88, "Jones"))
barSeries2.DataPoints.Add(New CategoricalDataPoint(109, "Marshall"))
Me.RadChartView1.Series.Add(barSeries2)
End Sub
Private Sub LegendElement_VisualItemCreating(sender As Object, e As LegendItemElementCreatingEventArgs)
e.ItemElement = New LegendItemElement(e.LegendItem)
e.LegendItem.Title = "<html><span><font=Arial><Color=Red><size=18>" & e.LegendItem.Title & "</span></html>"
e.ItemElement.DisabledTextRenderingHint = False
End SubRegards,
