GridTreeControl - DataTemplate CellType not working

Hi,

May I know if the GridTreeControl support DataTemplate columns?

I tried setting the StyleInfo.CellType = "DataTemplate" and nothing happens.

And also, is the MappingName of the GridTreeColumn mandatory?
Do you have any sample of creating new columns in the GridTreeControl that isn't bound to any source?

I would like to have a GridTreeControl that has a column with Button controls in them.

Is that possible?

All the existing samples only show GridDataControl

Thanks
