RadGridView disabling add/delete/edit rows

[dalexsoto]

Hi im using entity framework to bind the datasource of a RadGridView

private void cmbUsers_SelectedValueChanged(object sender, EventArgs e)
       {
           cmbUsers.ValueMember = "Id";
           var resguardos = from e1 in context.tblBienes
                                        where e1.IdResponsable == (long)cmbUsuarios.SelectedValue
                                        select new
                                        {
                                            Id = e1.IdBien,
                                            Descripcion = e1.descripcion,
                                            Estado = e1.estado,
                                            Placa_Anterior = e1.placaAnterior,
                                            Placa_Nueva = e1.placaNueva,
                                            Ubicacion = e1.ubicacion,
                                            Fecha_De_Asignacion = e1.fechaAsignacion,
                                            Etiqueta = e1.etiqueta,
                                            Procuraduria = context.tblProcuradurias.Where(e2 => (e2.IdProcuraduria == (long)cmbProcuradurias.SelectedValue)).Select((e2 => e2.ciudad)).FirstOrDefault()
                                        };
           rgvResguardos.DataSource = resguardos;
       }

rgvResguardos its a DataGridView and the result of the linq to entities its being given as datasource to it. i enabled Ading and enabled Editing on rgvResguardos but when i run my app it displays data but it doesnt allow me to add new rows nor editing or deleteing.

is there any way to enable this options? i know i have to take care of inserting, deleteing and updating info on the database.

Hello,

This happens because you are using Anonymous types, please create a concrete type and it will work as expected, and if possible create a BindingList<T> and bind that to the grid (for INotifyPropertyChanged).

Hope this helps, if you have any other questions or comments, please let me know,

Can we force the Add Row to display and handle it ourselves in some manner while still using the dynamic or object datatypes as our datasource?

CORRECTION: Nevermind, I had the ReadOnly flag set.  *facepalm*  It appears that dynamic datatypes still allow editing...as far as I can tell so far...
