problem with mark invalid cell in grid

[Prorok]

Hi All.
How can i mark invalid cell in grid?

I have some code:

cell.addCls('invalidClsStyle');

but, cls style does not restore after store.sync() or when i filtere grid.

Thanks in advance!

Thanks for the article
as a solution my problem, i set tdCls in the renderer function.
At first, When Ajax validation finished i dynamically added new property to the model (_value), and save validation information at the dynamically added properties (_value ).
then i force render by means of grid.getView().refresh().

at the render function i have something like that:

renderer: function(value, metadata, record) {
                    if (record._value)
                        metadata.tdCls += 'clsStyle';
                    return value;
                } },

Any criticism is welcome.
