I have placed an sqldatasouce on my page and set the datasource mode to datareader....

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NewUserList %>"
                        SelectCommand="SELECT [UserID] FROM [tblIDList] WHERE ([UserID] = @UserID)" DataSourceMode="DataReader">
                        <SelectParameters>
                            <asp:ProfileParameter Name="UserID" PropertyName="UserName" Type="String" />
                        </SelectParameters>
                    </asp:SqlDataSource>
I want to compare the userid to a text field to see if they match.  I can not figure out how to access the datareader  part of the sqldatasource.  Can someone point me in the right direction?  I am using vs2005 and visual basic.

I have tried this but get error...

Dim sdata As String
        Dim reader As SqlDataReader = CType(SqlDataSource1.Select(DataSourceSelectArguments.Empty), SqlDataReader)
        If reader.Read() Then
            sdata = reader("UserID").ToString
        End If
Thanks,
John
