ObjectDataSource does not display data objects in data source settings

I am using visual studio 2008, I have included the class in the AppCode folder and used it in ObjectDataSource.

If you tried all of the above, then his problem with the machine may be, your machine does not support this.

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 that, I was able to see client information in the GridView.

You can always manually enter the name of an object in objectDatasource in the format:

namespace.classname, App_Code

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

NTN.

You may need to mark your class and methods with some attributes to display them in the constructor. Take a look at DataObject and DataObjectMethod .

I had the same problem, the result was fixed by adding App_Code to TypeName ... a simple fix, but it took a long time to figure this out. (From an example)

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

Lightning old Q & A, but I just accidentally stumbled upon this topic, waving brains on this issue. My solution was to ensure that related classes are publicly accessible.

Perhaps you open as “Project” instead of “Website,” I don’t know why the Data object does not show me when it opens as “Project”.

I was directed to this question because I had a similar problem. My solution was obtained from the following answer provided by StevenMcD:

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

Make sure Build Action is set to Compile.

Classes in App_Code are not available

Check the web.config file for VS entries, such as partitions, that may cause this problem (delete entries and rebuild).
