RadScheduler1_AppointmentDataBound error on page post back

[Francesco]

I have make a scheduler based on your exemple. It Wok well, his is my method to inizialize object and dataBound
http://localhost:8301/radcontrols_aspnetajax/scheduler/examples/bindtolist/defaultcs.aspx

private void InitializeResources()
        {

            ResourceType resType = new ResourceType("User", false);

            resType.ForeignKeyField = "UserID";
            resType.Name = "User";

            RadScheduler1.ResourceTypes.Add(resType);

            //add uer
            DataView listUser = (DataView)ObjectDataSourceFilterContatti.Select();

            foreach (DataRow user in listUser.Table.Rows)
            {
                int key = Convert.ToInt32(user["idAnagrafica"]);
                string value = user["Nome"].ToString();

                Resource r = new Resource("User", key, value);
                RadScheduler1.Resources.Add(r);
            }
                 }

protected void RadScheduler1_AppointmentDataBound(object sender, SchedulerEventArgs e)
        {
            //recupero l'utente collegato all'appuntamento
            Resource userRes = e.Appointment.Resources.GetResourceByType("User");
            if (userRes != null)
            {
                string key = userRes.Key.ToString();
                   //DO SOMETHING...............
            }

}

now, if I change the InitializeResources() method in this way

ResourceType resType = new ResourceType("User", false);
            resType.DataSourceID = "ObjectDataSourceFilterContatti";
            resType.ForeignKeyField = "UserID";
            resType.KeyField = "idAnagrafica";
            resType.TextField = "Nome";
            resType.Name = "User";
            RadScheduler1.ResourceTypes.Add(resType);

it work on page load (the combo box User is populated correctly) but in past back during the method RadScheduler1_AppointmentDataBound in this row

Resource userRes = e.Appointment.Resources.GetResourceByType("User");

the userRes object is always null, why?

Hi Francesco,

I tried to reproduce the issue but to no avail.
I am interested where did you call the InitializeResources() method? Did you call it in the OnInit event? Could you please send me your full code so I can inspect it and help you?

yes I paste my full code, verry thanks...

                Resource UserRes = RadScheduler1.Resources.GetResource("Agente", key);
                //la assegno all'appuntamento in questione
                e.Appointment.Resources.Add(UserRes);
            }
        }
    }
}

I don't Understand how to use ForeignKeyField property, If I made a new ResourceType "Agente" object it work correctly if and only if the ForeignKeyField = "UserID" if I change this property to "MyID" I have a javascript generic error. I am very confused. I hope you can help me, thank a lot

Hi Francesco,

Unfortunately I am not able to see what is the problem without debugging your code.
Could you please open a new support thread and attach the full code in a .zip file so I can inspect it and help you?

Thank you!
