    [Resolved] Pie chart example


    I'm trying to use Pie chart example but it doesn't work with me.
    Code is very simple...

    <ext:Chart ID="Chart1" runat="server" Animate="true" Shadow="true" InsetPadding="60"
                <LegendConfig Position="Right" />
                                Data="<%# GenerateData() %>"                          
                                    <ext:Model runat="server">
                                            <ext:ModelField Name="Name" />
                                            <ext:ModelField Name="Data1" />
                                <Label Field="Name" Display="Rotate" Contrast="true" Font="18px Arial" />
                                <Tips TrackMouse="true" Width="140" Height="28" runat="server">
                                    <Renderer Fn="tipRenderer" />
    And the code behind:

    Partial Class _Default
        Inherits System.Web.UI.Page
        Public Class ChartItem
            Public Name As String
            Public Data1 As Double
            Public Data2 As Double
            Public Data3 As Double
        End Class
        Public Sub refreshPie()
            Chart1.GetStore().DataSource = GenerateData()
        End Sub
        Public Function GenerateData() As List(Of ChartItem)
            Dim chartsData As New List(Of ChartItem)(2)
            chartsData.Add(New ChartItem() With {.Name = "test", .Data1 = 20, .Data2 = 10, .Data3 = 33})
            chartsData.Add(New ChartItem() With {.Name = "test2", .Data1 = 80, .Data2 = 90, .Data3 = 77})
            Return chartsData
        End Function
    End Class

    I don"t have any js errors. I really don't understand why I don't see anything. Page is still blank...

    Can you help me please? :(

    Okay...I've found myself the problem...
    No render if the chart isn't included into a Panel for example..... Stupid error -_-'

    Including to a panel is not required. You have to provide width/height for a chart or place it inside a container with a layout handles subitems size (like FitLayout)
