 System: WinXP Pro SP2, ChartFX for .NET 6.2 (Development)

 I created simple page with chart anf DropDown. AutoPostBack for DropDown set to true. When I change selection in DropDown, I get gray rectangle instead of my chart.

Has anybody had such a problem?

Listings:

Test.aspx

  <asp:Table ID="Table1" runat="server" Width="100%" BorderWidth = "1" BorderColor="#BEBEBE">   <asp:TableRow>   <asp:TableCell>   <asp:DropDownList runat="server" AutoPostBack=true>   <asp:ListItem Text="First"></asp:ListItem>   <asp:ListItem Text="Second"></asp:ListItem>   </asp:DropDownList>   </asp:TableCell>   </asp:TableRow>   <asp:TableRow>   <asp:TableCell Width="100%" >       <chartfx:chart id="Graph" runat="server" >       </chartfx:chart>   </asp:TableCell>   </asp:TableRow>   </asp:Table> 

 Test.aspx.cs

  protected void Page_Load(object sender, EventArgs e)   {   PopulateGraph();   }   private void PopulateGraph()   {   Graph.OpenData(COD.Values, 1, (int)COD.Unknown);   Graph.Value[0, 0] = 1;   Graph.CloseData(COD.Values);   }
