How to set the label.text property to the data displayed in a dropdownlist. visual studio 2005

I need to set the label.text property to the data displayed in a dropdownlist.

Me.lblResource.Text = ddlResourceType.DataTextField returns the field name instead of the field value.

Source code for the aspx file

    <asp:Label ID="lblResourceType" runat="server" Text="Resource Type">
    </asp:Label>&nbsp;<br />
   
    <asp:DropDownList ID="ddlResourceType" runat="server" AutoPostBack="True"
      DataSourceID="dscResourceType"
      DataTextField="RT_Name" DataValueField="RT_ID">
    </asp:DropDownList>
   
    <asp:SqlDataSource ID="dscResourceType" runat="server"
      ConnectionString="<%$ ConnectionStrings:ResFinderSQLConnectionString %>"
        SelectCommand="SELECT [RT_ID], [RT_Name] FROM [Resource_Types]
      ORDER BY [RT_Name]" DataSourceMode="DataReader">
    </asp:SqlDataSource>

Source code for the aspx.vb file

    Protected Sub ddlResourceType_SelectedIndexChanged(ByVal sender As Object,
      ByVal e As System.EventArgs)
      Handles ddlResourceType.SelectedIndexChanged

        Me.lblResource.Text = ddlResourceType.DataTextField

Thanks,
