How am I supposed to declare my SelectMethod and Parameter? No matter what I try, I get the error "ObjectDataSource 'ObjectDataSource' could not find a non-generic method 'MyMethod' that has parameters: myParameter.". Here's my code as of right now:

<asp:ObjectDataSource ID="ObjectDataSource" runat="server" SelectMethod="Third.Party.Library.MyMethod" TypeName="Third.Party.Library.SomeObject">
    <SelectParameters>
        <asp:Parameter Name="myParameter" Type="String" />
    </SelectParameters>
</asp:ObjectDataSource>

public static SomeObject MyMethod(string myParameter)
{
    // Code here
}

Is the class public?

Yes, the class is public. I have no problems accessing and databinding to the method from the codebehind.

Hello Faize,

I mean that since you can call the method inside the proj, but it can never be found by ObjectDataSource...

Way 1——Re-compile the whole proj, and re-refer the dll and try again.

Way 2——Create another cs file, where you can refer and call the dll method, and for the objectDataSource, plz use your own method instead.
