It is possible, but not yet 🙂
The DGV cells in Wisej have the Control property which is meant to be used to include a control in the cell, any cell. The top left cell is DGV.TopLeftHeaderCell, so you can assign a control to the call, the control can be created dynamically and all the events are wired back normally.
However the property is not wired on the client side yet and I’m not sure it will be by the first release.
Got you. And I understand that your target first release date is fast approaching. What I asked maybe just considered as an enhancement and can be done after the first release if you are running out of time.
Just please include that in your TDL.
