Blink

I have a virtual grid and the cellchangeevent is not triggered his.grid.Model.CellsChanged += new GridCellsChangedEventHandler(grid_CellsChanged); The grid_CellsChanged is never reached. I change data through the QuerryCellInfo

This event is only raised with something calls gridControl1.ChangeCells. This method will be called when your user makes a change in the grid or if some method retrieves a style by indexing the Model and changes this style. If the only changes are done directly in your outside datasource, the grid will not raised CellChanged. If you need to be notified when your outside datasource is changed external to the virtual GridControl, then you would have to look to your datasource to raise some event to notify listeners of the change.
