If the control has no scroll bars the OffsetChanged and OversizeChanged events are not fired. Use the ScrollBars property of the control to determine which scroll bars are visible within the control. The OffsetChanged event is not fired when the user scrolls the chart's part of the control. In this case, the DateChange event is fired. The OffseyChanged event is fired only when the user scrolls horizontally the columns section of the control, or when the user scrolls vertically the items part of the control ( including the chart part ). The ScrollPos property can be used to programmatically scroll the control's content at giving position.

The following VB sample displays the new scroll position when user scrolls horizontally the control:

Private Sub G2antt1_OffsetChanged(ByVal Horizontal As Boolean, ByVal NewVal As Long)
    If (Horizontal) Then
        Debug.Print "The horizontal scroll bar has been moved to " & NewVal
    End If
End Sub

The following VC sample displays the new scroll position when the user scrolls vertically the control:

void OnOffsetChangedG2antt1(BOOL Horizontal, long NewVal) 
{
	if ( !Horizontal )
	{
		CString strFormat;
		strFormat.Format( "NewPos = %i\n", NewVal );
		OutputDebugString( strFormat );
	}
}

The following VB.NET sample displays the new scroll position when the user scrolls vertically the control:

Private Sub AxG2antt1_OffsetChanged(ByVal sender As Object, ByVal e As AxEXG2ANTTLib._IG2anttEvents_OffsetChangedEvent) Handles AxG2antt1.OffsetChanged
    If (Not e.horizontal) Then
        Debug.WriteLine(e.newVal)
    End If
End Sub

The following C# sample displays the new scroll position when the user scrolls vertically the control:

private void axG2antt1_OffsetChanged(object sender, AxEXG2ANTTLib._IG2anttEvents_OffsetChangedEvent e)
{
	if ( !e.horizontal )
		System.Diagnostics.Debug.WriteLine(e.newVal);
}

The following VFP sample displays the new scroll position when the user scrolls vertically the control:
