Hi,

I'm trying to set up a web site with Class files in the App_Code directory.  When using the ObjectDataWizard configuration set up wizard, the first screen reads "Select your business object"

The dropdown only contains references to my master page files, no sign of the .cs files I have created

Hi,

Have You specified the component model attributes in your class files? I.e:

[System.ComponentModel.DataObject]

public partial class MyDataAccess {
    [System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, true)]
    public static DataSet GetMyData()    {

    }
}

Thanks for the quick response.

I don't think I have.  Would I do this in the CS file?  I'm new to .net, so I've added the class file I'm trying to use

using System;
using System.Data;
using System.Configuration;
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;
using System.Collections.Generic;
using System.Data.SqlClient;
 
/// <summary>
/// Summary description for TimePlanData
/// </summary>
/// 
 
public class TimePlanData
{
 
    private string _conString;
 
	public TimePlanData()
	{
        _conString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
	}
 
    public IList<TimePlan> GetTimePlans(int idFilter)
    {
        string sql = "SELECT * FROM TimePlan ";
 
        if (idFilter > 0)
        {
            sql += "where tp_id=" + idFilter;
        }
 
        sql += " order by tp_name";
        SqlConnection connection = null;
        IDataReader reader = null;
 
        IList<TimePlan> result = new List<TimePlan>();
        try
        {
            connection = new SqlConnection(_conString);
            connection.Open();
            IDbCommand cmd = connection.CreateCommand();
            cmd.CommandText = sql;
            reader = cmd.ExecuteReader();
            while (reader.Read())
            {
                result.Add(new TimePlan(reader));
            }
        }
        catch (Exception ex)
        {
        }
        finally
        {
            if (reader != null)
                reader.Close();
            if (connection != null)
                connection.Close();
        }
        return result;
    }
 
}

Hi,

You should get by through changing your class file as the attached snippet.

/Carl.
using System;
using System.Data;
using System.Configuration;
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;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.ComponentModel;
 
/// <summary>
/// Summary description for TimePlanData
/// </summary>
/// 
 
[DataObject(true)]
public class TimePlanData
{
 
    private string _conString;
 
	public TimePlanData()
	{
        _conString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
	}
    [DataObjectMethodAttribute(DataObjectMethodType.Select, true)]
    public IList<TimePlan> GetTimePlans(int idFilter)
    {
        string sql = "SELECT * FROM TimePlan ";
 
        if (idFilter > 0)
        {
            sql += "where tp_id=" + idFilter;
        }
 
        sql += " order by tp_name";
        SqlConnection connection = null;
        IDataReader reader = null;
 
        IList<TimePlan> result = new List<TimePlan>();
        try
        {
            connection = new SqlConnection(_conString);
            connection.Open();
            IDbCommand cmd = connection.CreateCommand();
            cmd.CommandText = sql;
            reader = cmd.ExecuteReader();
            while (reader.Read())
            {
                result.Add(new TimePlan(reader));
            }
        }
        catch (Exception ex)
        {
        }
        finally
        {
            if (reader != null)
                reader.Close();
            if (connection != null)
                connection.Close();
        }
        return result;
    }
 
}

Excellent, thanks!

I take it for every other method I add, for example an Insert method, I put the line:
 [DataObjectMethodAttribute(DataObjectMethodType.Insert, true)]

before it?

Hi,

I'm trying to add an Insert routine to this class file, but the ObjectDataSource wizard is only detecting the "GetData" method

It is not showing the "AddData" method, and when I type in "[DataObjectMethodAttribute" this is not detected in the intelisense


[DataObjectMethodAttribute(DataObjectMethodType.Insert, true)]
    public void AddData()
    {
 
    }
 
    [DataObjectMethodAttribute(DataObjectMethodType.Select, true)]
    public IList<Data999> GetData(string telNumber)
    {
