Code-databinded combo dropdown issue

[Jorge Pascual]

Hello

I'm populating a radcombobox control programatically with the code shown below. I know combo is filled with all the items it must, (i can test this using items.count or selecteditem properties), but the fact is that when I click the dropdown arrow, the combo doesn't dropdown, just stays as a single textbox showing only the current item.

This is the code sample:
 

 

 

 

Public Sub CargarMarcas(ByRef cmbMarcas As Telerik.WinControls.UI.RadComboBox)
            Using ta As New ArqBD.dsERPConfigTableAdapters.MARCASTableAdapter
                Using dt As New ArqBD.dsERPConfig.MARCASDataTable
                    ta.Fill(dt)
                    cmbMarcas.DisplayMember = "Nombre"
                    cmbMarcas.ValueMember = "Identificador"
                    cmbMarcas.DataSource = dt
                End Using
            End Using
        End Sub

Note: I've tried the same code in form's load event and in a separate public module (as the sample), and in both cases it doesn't work. Is there something I'm missing? Thank you in advance

SOLVED!!!!

With Using...End Using the combobox lost its items when the dataset is disposed.
With dim the problem is solved.
