Get Datalist label in c#

Hi I have a datalist as follows:

<asp:DataList CssClass="courseNameInfo" ID="CourseData" runat="server" DataSourceID="CourseNameSQL">
                <ItemTemplate>
                 <strong> Course Name:</strong><br /> 
                    <asp:Label ID="CourseLabel" runat="server" Text='<%# Eval("Course") %>'></asp:Label>
                </ItemTemplate>
            </asp:DataList>

I am trying to gt the labels value into my download button click event, This is what I tried:

 Label lbl = (Label)CourseData.Items[0].FindControl("CourseLabel");

However, I am getting an error message saying:

Cannot convert type 'System.Web.UI.Control' to System.Reflection.Emit.Label

How would I get the label any ideas? Thanks
