Hi!

I have the following code that fills-in the combo datasource from an enumelation.

  Private Function FillComboWithEnum(Of EType)(ByVal combo As UltraCombo) As UltraDataSource

    Dim dataSource As New UltraDataSource

    Dim enumType = GetType(EType)

    dataSource.Band.Columns.Add(VALUE_NAME, enumType)
    dataSource.Band.Columns.Add(TEXT_NAME, GetType(String))

    Dim enums As Array
    enums = [Enum].GetValues(enumType)

    For Each item In enums
      Dim ienum As [Enum] = CType(item, [Enum])
      Dim stringValue = ienum.GetStringValue()
      If String.IsNullOrEmpty(stringValue) Then
        stringValue = ienum.ToString()
      End If
      dataSource.Rows.Add(New Object() {ienum, stringValue})
    Next item

    combo.DataSource = dataSource

    combo.ValueMember = VALUE_NAME
    combo.DisplayMember = TEXT_NAME

    combo.DisplayLayout.Bands(0).Columns(0).Hidden = True

    Return dataSource
  End Function

So, everything works good, but the combo now have 2 columns. I want to hide the value column-the first column).

But when I run the code, I have an exception, saying that index out of range or key not not found. Is not found because there is any column in the DisplayLayoutBand. Why??

DataSource have 2 columns, but why don't the DisplayLayout band !!?
