an exception - Please have a look.

I have implemented custom CellModel (using an example from syncfusion) a long time ago. I was playing around with the GridControl, in which the new CellModel is hosted. Playing around means.. right clicking and double clicking frequently. When I saw the application log, it was showing this exception. Please comment on it. Is their any workaround for it.

I searched both our forums and our Direct Trac database to see if anyone else has reported a callstack that included Syncfusion.Windows.Forms.Grid.GridModelFloatingCells.CanFloatCell, and could not find any hits on the method.

If you are not using floating cells, then you can try explicitly setting

Me.grid.FloatCellsMode = GridFloatCellsMode.None

to see if that affects this problem.

If you own our source code, you can use teh Assembly Manager to build debug versions of our libraries so you can step into our code to see exactly what is null in that method.
