Hi,
We will need more information to answer this question:
-When you talked about Cell Editor and Viewer which exact control are you talking about (the Microsoft Datagrid, The Xceed Toolkit’s DataGrid or the Xceed DataGrid for WPF (Complete edition), or any other control?)
– When you mentioned the documentation example, the TrackBar. Which example are you referring to exactly? The Toolkit LiveExplorer does not include an example named “TrackBar”.
– Also you have mentioned the CellViewerManager, however the Toolkit does not include this control.
