The selected layer in the layer control.
[Visual Basic 6.0] Property SelectedLayer As ILayer
[Visual Basic .NET] Public ReadOnly Property SelectedLayer As ILayer
[C#] public ILayer SelectedLayer {get;}
Returns the currently selected layer in the table of contents.
To select a layer in the table of contents, obtain an IContentsView reference via IMxDocument::ContentsView, then use either IContentsView::AddToSelectedItems or IContentsView::SelectedItem. To learn more, read the help for IContentsView.
The following simple VBA subroutine checks to see if the selected layer is a group layer or a feature layer.
Public Sub CheckSelectedLayer()
Dim pMxDocument As IMxDocument
Set pMxDocument = Application.Document
Dim pLayer As ILayer
Set pLayer = pMxDocument.SelectedLayer
If TypeOf pLayer Is IGroupLayer Then
' we have a group layer (GroupLayer)
MsgBox pLayer.Name
ElseIf TypeOf pLayer Is IGeoFeatureLayer Then
' we have a feature layer
MsgBox pLayer.Name
End If End Sub
