'ChartSeriesType' is ambiguous in the namespace 'Telerik.Charting'

Hi, 
I am getting the error 'ChartSeriesType' is ambiguous in the namespace 'Telerik.Charting'. I have Telerik.Web.UI dll in my bin folder. 
Here is the code

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<%@ Register TagPrefix="telerik" Namespace="Telerik.Charting" Assembly="Telerik.Web.UI" %>

<asp:Content ID="Content1" ContentPlaceHolderID="phCon1" Runat="Server">
<table><tr><td><asp:Label ID="lblMessage" Visible="false" runat="server" /></td></tr></table>
    <table>
        <tr>
        <td>From :
        <telerik:RadDatePicker ID="DateTextCalendar1" runat="server"></telerik:RadDatePicker></td>
        <td>To :<telerik:RadDatePicker ID="DateTextCalendar2" runat="server"></telerik:RadDatePicker>
</td>
        <td><asp:Button runat="server" ID="btnSubmit" Text="Apply" /></td>
    </tr>
    </table>
  <asp:PlaceHolder ID="phTestDash" Visible="true" runat="server">
        
      <telerik:RadChart ID="RadChart1" DataSourceID="SqlDataSource1" runat="server" Skin="Vista"
                        Width="465px" Height="260px" DefaultType="Line" 
                        AutoLayout="true" AutoTextWrap="true" CreateImageMap="false"  >
                        <ChartTitle>
                            <TextBlock Text="Test">
                            </TextBlock>
                          </ChartTitle>
                        <Series>
                            <telerik:ChartSeries Name="Actions" Type="Line" DataYColumn="iActions">
                                <Appearance LegendDisplayMode="ItemLabels">
                                </Appearance>
                            </telerik:ChartSeries>
                        </Series>
                        </telerik:RadChart>
  </asp:PlaceHolder>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Test %>" ProviderName="System.Data.SqlClient" 
        SelectCommandType="StoredProcedure" SelectCommand="Test_GET">
        <SelectParameters>
            <asp:Parameter Name="TestID" DbType="Guid" />
            <asp:Parameter Name="iTestStartDateID" Type="Int32" />
            <asp:Parameter Name="iTestEndDateID" Type="Int32" />
        </SelectParameters>
    </asp:SqlDataSource>
</asp:content>

And the code behind is

Imports Telerik.Web.UI
Protected Sub LoadGraph()
             Try
                    dt = function(test)

                If dt Is Nothing Or dt.Rows.Count <= 0 Then
                    ShowMessage("No Data Available", False)
                    phTestDash.Visible = False
                    Exit Sub
                End If

            Catch ex As Exception
                ShowMessage(ex.Message, True)
            End Try
        End Sub


I went thru the forum and removed the reference from the corresponding dll. We are your customer and we need a solution for it to go forward.

Hi Priya,

This might happen if you still have a reference to Telerik.Charting.dll. It is now merged into Telerik.Web.UI.dll, so you need to make sure it is not referenced anywhere in your project.
