I have a big GridControl of FormulaCells with lots of interdependent formulas. Many of the cells are set to read only.
When I scroll the cells with formulas onto the screen, the CPU stays at 100% and appears to be constantly redrawing.
If I remove the read only attribute from all cells, the CPU remains at 0%.
Is the read only state preventing the grid from saving its own FormulaTags into the GridModel??

You can handle the CurrentCellStartEditing event, and if grid[grid.CurrentCell.RowIndex, grid.CurrentCell.ColIndex].CellType == "FormulaCell", you can set e.Cancel = true. This will prevent the formula cells from being editable without using the ReadOnly property which locks out style changes.

We have corrected this problem in our library code.
In the next release(it is in the works, but I do not know when), formula cells which are readonly will be properly calculated and displayed with the values being cached in the FormulaTag object avoiding this CPU spike.
