Pie chart graphics is not shown

[Carlos]

Hi, I'm working on an app asp.net and using radchart control in it, I wrote the next test code:

HTML

<form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>
    <div>
        <telerik:RadChart ID="chrChart" runat="server" >
            <PlotArea>
                <EmptySeriesMessage  Visible="True">
                    <Appearance Visible="True">
                    </Appearance>
                </EmptySeriesMessage>
            </PlotArea>
        </telerik:RadChart>
    </div>
</form>

vb.net code

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    chrChart.Clear()
    chrChart.AutoLayout = True
    chrChart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Font = New Font("Arial", 10)
    chrChart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Color = Color.Black
    chrChart.PlotArea.XAxis.AutoScale = False
    Dim loDataSeries As New ChartSeries("Chart test", ChartSeriesType.Bar)
    loDataSeries.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.ItemLabels
    Dim myItem1 As New ChartSeriesItem(10, "myitem1")
    myItem1.Name = "myitem1"
    Dim myItem2 As New ChartSeriesItem(20, "myitem2")
    myItem2.Name = "myitem2"
    loDataSeries.AddItem(myItem1)
    loDataSeries.AddItem(myItem2)
    chrChart.AddChartSeries(loDataSeries)
End Sub

this code showed the bar chart correctly, but When I changed the ChartSeriesType to Pie, the graphics is not shown, (see image attached).

Dim loDataSeries As New ChartSeries("Chart test", ChartSeriesType.PIE)

When I comment the next code:

'chrChart.PlotArea.XAxis.AutoScale = False

I get the next exception

    Unable to cast object of type 'Telerik.Charting.ChartXAxis' to type 'Telerik.Charting.ChartYAxis'.

regardless if the  ChartSeriesType is Bar or Pie, I get the error.

What am I doing wrong?

Hi Carlos,

I have examined your code and created a test project, but unfortunately I couldn't reproduce your problems. As far as I know there are no changes in the RadChart codebase between these 2 versions you mentioned that could cause your issues. 

Please examine the attached project and check for any inconsistencies with yours. I hope this will help.

All the best,

I have tested sample program using version 2012.2.925.40 and it still have same problem. I refer the component in download folder.

Thanks for you response, I have loaded the assembly that you put in the example project, and it's worked, the assembly
that I downloaded from your page seems to be faulty for it doesn't work eather in my project or yours, it should be noted that the size of telerik bin in my project is different that yours, but is the same version(in a few bytes).

Hello,

We have been able to identify the cause for this error and the fix will be available with this week's latest internal build which you can download from your account.
