    copied!<p>Greetings!</p> <p>I'm creating a User Control that will display data in a GridView control. We are using n-tier architecture and the data in question is retrieved from our database and returned to us as a ReadOnlyCollection. OurNewObject is a class containing several properties and an empty constructor that takes no parameters - it's in the following namespace: Acme.ObjectModel.</p> <p>In the user control, I have the following:</p> <pre><code>&lt;asp:GridView ID="ourGrid" runat="server" DataSourceID="ourDataSource"&gt; &lt;columns&gt; &lt;asp:BoundField DataField="Name" HeaderText="Full Name" /&gt; &lt;asp:BoundField DataField="Gender" HeaderText="Gender" /&gt; &lt;asp:BoundField DataField="BirthYear" HeaderText="Year of Birth" /&gt; &lt;asp:BoundField DataField="JoinDate" HeaderText="Date Joined" /&gt; &lt;/columns&gt; &lt;/asp:GridView&gt; &lt;asp:ObjectDataSource ID="ourDataSource" runat="server" SelectMethod="GetTopUsers" TypeName="Acme.Model.OurNewObject"&gt; &lt;/asp:ObjectDataSource&gt; </code></pre> <p>In the User Control's code behind, I have the following public method:</p> <pre><code>public ReadOnlyCollection&lt;OurNewObject&gt; GetTopUsers() { return (OurDataProxy.GetJustTheTopUsers()); } </code></pre> <p>When I place the User Control on a Web form and run it, I get the following message:</p> <p><strong>ObjectDataSource 'ourDataSource' could not find a non-generic method 'GetTopUsers' that has no parameters.</strong></p> <p>So my questions are:</p> <ol> <li>Am I using the ObjectDataSource incorrectly?</li> <li>Is there a more proper way to use the ObjectDataSource in this situation?</li> </ol> <p>Thanks.</p>
