grid dataProcessor after update - cell-style lost

hello dhtmlx-support team,

after update (dataProcessor) - the grid-cell style get lost.

there are style-rules, that we need to define for updated cells / rows?


this fix the problem…
dp.attachEvent(“onRowMark”,function(id,state,mode,is_invalid){ return false; })
… but - no update-effect

Cell styles defined in xml should stay after updating of the grid.
Also onRowMark event shouldn’t cause the denying of the row update.

If issue still occurs - please provide a complete demo.
