The SelectObjectColor / SelectObjectTextColor property specifies the colors to show the selected elements ( while the control has the focus ). The SelectObjectColorInactive / SelectObjectTextColorInactive property specifies the color to show the selected elements ( while the control is not focused ). The SelectObjectStyle property specifies the style to show the selected elements ( like changing the element's background/foreground colors, showing a border around the selected elements, and so on ). Use the Background(exSelectObjectRectColor) property to specify the color to show the rectangle that highlights the elements that intersect the dragging rectangle.

The SingleSel property specifies whether the surface allows selecting one or multiple elements. The SelCount property counts the number of selected elements. The SelElement property returns the selected element based on its index in the selected elements collection. The Selection property sets or gets a safe array of selected elements. The AllowSelectObject property indicates the keys combination to allow user selecting new elements. The AllowSelectObjectRect property specifies the keys combination so the user can select the elements from the dragging rectangle. The AllowSelectNothing property indicates whether the selection is cleared once the user clicks any empty area on the surface. The SelectAll method selects all elements in the chart. Use the UnselectAll method to unselect all elements on the surface.

The following VB sample enumerates the incoming elements ( of selected elements ):

Private Sub Surface1_SelectionChanged()
    With Surface1
        Dim s As Variant
        For Each s In .Selection
            Debug.Print "Incomming Elements of " & s.ID & "are: "
            With s

                    Debug.Print i.ElementFrom.ID
                Next
            End With
        Next

End Sub

The following VB sample enumerates the outgoing elements ( of selected elements ):
