Example
The following code sample demonstrates how the UltraListView's KeyActionMappings collection can be used to modify the default keyboard for the control. In this example, the default mappings for the 'Home' and 'End' keys are removed, and replaced with mappings which navigate to the first/last item on an iconic row. The default mappings for 'Home' and 'End' are then remapped to require the Control key, so that the Ctrl+Home/Ctrl+End key combinations navigate to the first/last item displayed by the control, respectively:

Imports Infragistics.Win

        '	The custom key mappings only apply to the iconic views, and multi-column list view
        If (Me.ultraListView1.CurrentState And UltraListViewStates.SupportsHorizontalItemNavigation) = UltraListViewStates.SupportsHorizontalItemNavigation Then

            '	Iterate the KeyActionMappings collection, and remove all mappings for
            '	the 'Home' and 'End' keys
            Dim keyMappings As UltraListViewKeyActionMappings = Me.ultraListView1.KeyActionMappings

            Dim i As Integer
            For i = keyMappings.Count - 1 To 0 Step -1

                keyMapping = keyMappings(i)
                If (keyMapping.KeyCode = Keys.Home Or keyMapping.KeyCode = Keys.End) Then
                    keyMappings.Remove(keyMapping)
