IContentsView.ContextItem Property

The context item (could be an enumerator).

[Visual Basic .NET]
Public Property ContextItem As Object
[C#]
public object ContextItem {get; set;}

Product Availability

Available with ArcGIS Desktop.

Remarks

You need at least to write a minimalistic implementation of this property as shown here:

Private m_ContextItem as Variant

Private Property Let IContentsView_ContextItem(ByVal RHS As Variant)
  m_ContextItem = RHS
End Property

Private Property Get IContentsView_ContextItem() As Variant
  IContentsView_ContextItem = m_ContextItem
End Property

The ContextItem property will contain the item on which the user makes a right-click in the TOC and at this point a context menu may be shown.

At 9.0 a default context menu is shown when the user right-clicks in your custom TOC. If you need to get rid of this menu in order to implement your own you will find the Selectable Layers Tab example valuable.
