3D Chart --> Object reference not set ...

[Θανάσης]

Hi

I have the following code and I'm taking an "Object reference not set ..." when I use Bar3DSeriesDefinition.

But when I set SeriesDefinition to a 2D definition (e.g. BarSeriesDefinition), everything is OK !!!

What I'm doing wrong?

    Dim dt As New DataTable
    dt.Columns.Add("Year", GetType(String))
    dt.Columns.Add("Sales", GetType(Double))
    dt.Rows.Add("2007", 37000)
    dt.Rows.Add("2008", 42000)
    dt.Rows.Add("2009", 47000)
    dt.Rows.Add("2010", 44000)

    With Me.RadChart1
      Dim sm As New SeriesMapping
      sm.SeriesDefinition = New Bar3DSeriesDefinition 'BarSeriesDefinition
      sm.ItemMappings.Add(New ItemMapping("Year", DataPointMember.XCategory))
      sm.ItemMappings.Add(New ItemMapping("Sales", DataPointMember.YValue))
      .SeriesMappings.Add(sm)
      .ItemsSource = dt
    End With

Hi Thanasis,

Thanks for the stack trace. However, after inspecting it we tried to reproduce the problem, however, we couldn't manage to cause the exception. I am attaching my sample app code. We would really appreciate it if you can modify it, or otherwise send us a running application which exhibits the problem. Once we are able to repro the bug it will be trivial to fix it.

I'm trying to attach a zip file with the project you are asking, but only image files are accepted in this forum.

How can I send to you this file?

Hello Thanasis,

You can open up a support ticket or upload the project file somewhere on a public web server.

OK. Thanks.

Hi Thanasis,

Thanks for the project. There seems to indeed be a problem with RadChart 3D series in WPF 4.0. We are currently investigating the issues. A temporary work-around is to re-target your application to .NET 3.5.

Best wishes,
