You might need to mark your class and methods with some attributes for them to show up in the designer. Look at DataObject and DataObjectMethod.

Check you web.config file for VS entries such as sections that might cause this issue (remove entries and rebuild).

I was directed to this question because I had a similar issue. My resolution came from the following answer, provided by StevenMcD:

Right click on the .cs file in the App_Code folder and check its properties.

Make sure the "Build Action" is set to "Compile".

Classes residing in App_Code is not accessible

Mouldy oldie Q&A but I just happened to stumble on this thread while wracking my brain on this issue. My solution was to ensure the related classes are all public.

If you have tried all the above, then its your machine issue may be your machine do not support that.

Maybe you are opening as "Project" instead of "Website", I do not know why the Data Object does not shows me when is opened as "Project".

I had the same problem, ended up fixing by adding App_Code to TypeName... simple fix but took a lot of time to realize it. (From example)

<asp:ObjectDataSource ID="ObjectDataSource1"
     SelectMethod="GetCustomers"
     TypeName="MyNamespace.App_Code.CustomerManager"
     runat="server">
</asp:ObjectDataSource>

In aspx

<asp:GridView ID="GridView1" 
     AutoGenerateColumns="true" 
     DataSourceID="ObjectDataSource1" runat="server">
</asp:GridView>

<asp:ObjectDataSource ID="ObjectDataSource1"
     SelectMethod="GetCustomers"
     TypeName="MyNamespace.CustomerManager"
     runat="server"></asp:ObjectDataSource>

In .cs (inside App_Code)

namespace MyNamespace
{
    public class Customer
    {
        public string Name { get; set; }
    }

    public class CustomerManager
    {
        public List<Customer> GetCustomers()
        {
            List<Customer> cust = new List<Customer>();
            Customer c = new Customer();
            c.Name = "sampleName";
            cust.Add(c);
            return cust;
        }
    }
}

After this I was able to see the Customer details in the GridView.

You can always manually type in the object's name into the objectDatasource, in the format of:

namespace.classname, App_Code

App_Code works for web site projects; otherwise, specify the name of the assembly of the web project if the web application project template.

HTH.
