I am trying to populate a ComboBox with data from a access db. I have the following code that works in a normal combobox, but with the radcombobox does nothing:

                Dim ComboBox1 As New Telerik.WinControls.UI.RadComboBox 
 
                Dim cn As OleDbConnection 
                Dim connString As String = ligacao 
                cn = New OleDbConnection(connString) 
 
                cn.Open() 
                Dim da As New OleDb.OleDbDataAdapter(sql, cn) 
 
                Dim ds As DataSet = New DataSet 
                da.Fill(ds, "Tabela"
 
                With ComboBox1 
                    .DataSource = ds.Tables(0) 
                    .DisplayMember = "D1" 
                    .ValueMember = "D2" 
                End With 

Can you tell me what I have to change to make it work?

Thanks

Hello R,

Thank you for the question.

Please keep the following in mind when creating and binding RadComboBox in run-time:
  1. Add your instance of RadComboBox to its parent form before data-binding occurs.
  2. Set its ValueMember and DisplayMember properties before setting its DataSource. This will significantly increase the performance.
I hope this is helpful. If you have other questions do not hesitate to contact me again.

 
All the best,
