  Okay, I've managed to get a pretty good version of a CheckedListBox control by using the ListView control as a basis.  Here's the class I created.  If you add one  ColumnHeader to this "enhanced" ListView and set the width to the width of the ListView - 16, it comes out looking pretty good.

  clbNew = New cfCheckedListBox

  clbNew.View = View.Details

  clbNew.HeaderStyle = ColumnHeaderStyle.None

  clbNew.CheckBoxes = True

  Public Class cfCheckedListBox

  Inherits System.Windows.Forms.ListView

  Private mMultiSelect As Boolean = False

  Private mSelectedIndex As Integer = -1

  Property MultiSelect() As Boolean

  Get

  MultiSelect = mMultiSelect

  End Get

  Set(ByVal Value As Boolean)

  mMultiSelect = Value

  End Set

  End Property

  Property SelectedIndex() As Integer

  Get

  SelectedIndex = mSelectedIndex

  End Get

  Set(ByVal Value As Integer)

  mSelectedIndex = Value

  End Set

  End Property

  Private Sub CheckedListBox_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles MyBase.ItemCheck

  If Not Me.MultiSelect Then

  If e.NewValue = CheckState.Checked Then

  If Me.SelectedIndex <> -1 Then

  Me.Items.Item(Me.SelectedIndex).Checked = False

  End If

  Me.SelectedIndex = e.Index

  Me.Items.Item(e.Index).Selected = True

  End If

  End If

  End Sub

  End Class

  One way to get similiar functionality with multiple selection support is to use ListView control.If you set the View property of the ListView to List you will get a ListBox alike look and feel. You may use  SelectedIndicies property to get the indicies of the selected items.

  Sort of yes, sort of no...
  
  To get multiple selection capability you need to have the CheckBoxes property set to True, which wouldn't be all that bad if it worked like a Checked ListBox in the larger Framework.  When you tap on an item in the ListView it only highlights the text of the item and not the white space to the right of it in the way that a ListBox does.  Coming from a ListBox that had multiple selection capability to a ListView is sort of a step down in application appearance.

  I'm working ListViews in Compact Framework 2, but cant get multi-selection working. I have checkboxes set to 'true' and view property as 'list'. Is it simply not supported

  Yes it looks great, but I can't get the list of selected items out of it :)
