Hi Otomar,


Thanks for your update.


You can able to cancel the editing for particular column by handling the beginEdit event like below code snippet , thus making it as a read only column.


Code snippet





taskIdMapping: "taskID",

beginEdit: "beginEdit",




function beginEdit(args) {

var editedData = args.data;

var column = this.getColumns();


if (column[args.columnIndex].mappingName == " taskID ")


   args.cancel = true;




For your reference here with we have attached the sample for cancel the editing in TaskId column with updated source and it can be downloaded from the following location.

Please let us know if need more information on this.

I tested the provided code an I found it not working. The code threw a java script error, because the args parameter object does not have the 'columnIndex' attribute.
