ObjectDataSource 's' could not find a non-generic method GetAllUsers

Question

I've looked over the web and have found loads of answers none of which have helped me resolve this issue!

I have a method in a data project. I then have a project with the displaying element.

The code-behind:

public static DataTable GetAllobjs(SPWeb objWeb)
{
    DataTable tmpData = new DataTable();
    try
    {
        allProjects.Columns.Add(ColumnNames.1);
        allProjects.Columns.Add(ColumnNames.2);
        allProjects.Columns.Add(ColumnNames.3);
        allProjects.Columns.Add(ColumnNames.4);
        allProjects.Columns.Add(ColumnNames.5);
        allProjects.Columns.Add(ColumnNames.6);
        allProjects.Columns.Add(ColumnNames.7);
        allProjects.Columns.Add(ColumnNames.8);
        allProjects.Columns.Add(ColumnNames.9);

        //Get the raw project data 
        List<obj> data= DataAquisition.GetAllobj(objWeb);

        /// Loop through the raw data.
        foreach (obj currentInformation in data)
        {
            // Creates a new data row containing information required and adds it to the DATAtable
        }
    }
    catch (Exception exc)
    {
        // Logs errors here
    }
    return tmpData;
}

In the page behind(cs) of the user control i have a Method that calls GetAllobjs(SPWeb objWeb)

[DataObjectMethodAttribute(DataObjectMethodType.Select, true)]
public DataTable GetAllUsers()
{
    return Data.GetAllobjs(SPContext.Current.Web);
}

Then the page load:

ObjectDataSource d = new ObjectDataSource();
d.ID = "s";
d.SelectMethod = "GetAllUsers";
d.TypeName = SPGridView.GetType().AssemblyQualifiedName;
this.Controls.Add(d);
/// Apply a data source to the SPGrid View
SPGridView.DataSourceID = d.ID;

Then on the create child control i create and bind my fields to the SPGridview and call the databind.

I thought this would work but i am getting the error. I'm not sure if i am missing some more component model [] tags somewhere i was hoping someone could possibly point out where i am going wrong.

Was it helpful?

Solution

Change:

d.TypeName = SPGridView.GetType().AssemblyQualifiedName;

to:

 d.TypeName = this.GetType().AssemblyQualifiedName;

Example: Default.aspx.cs 

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

namespace Q11454649WebApp
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                ObjectDataSource d = new ObjectDataSource();
                d.ID = "s";
                d.SelectMethod = "GetAllUsers";
                //d.TypeName = SPGridView.GetType().AssemblyQualifiedName;
                d.TypeName = this.GetType().AssemblyQualifiedName;
                this.Controls.Add(d);
                /// Apply a data source to the SPGrid View
                SPGridView.DataSourceID = d.ID;
            }
        }

        [System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, true)]
        public string[] GetAllUsers()
        {
            return new string[] { "Joe", "Alan", "Michel" };
        }
    }                              
}
