DataBinding to ComboBox in VB.Net

Question

I'm trying to bind CheckedListbox's Cheched items to Combobox my code is given below

Private Sub chklColumns_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chklColumns.SelectedIndexChanged        
            cmbSort.DataSource = chklColumns.CheckedItems
End Sub

whenever I check an item first time it loads one item to the Combobox, but when I select second item still I have single item in the Combo... am I doing anythig wrong in my above code ??

Answer 1

You should reset the binding by setting the DataSource to Nothing before setting a new value:

Private Sub chklColumns_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chklColumns.SelectedIndexChanged        
    cmbSort.DataSource = Nothing
    cmbSort.DataSource = chklColumns.CheckedItems
End Sub
