Hidden columns are being copied to clipboard at gridToClipboard() action.
Possible other clipboard actions are broken to.
This is expected behaviour. Before putting string with grid to the clipboard gridToClipboard() method serialize grid to the CSV format. You can use setSerializableColumns(list) method to set which column shouldn’t be serialized to the CSV. (list - list of true/false values separated by comma, if list empty then all fields will be serialized); You can find more information here dhtmlx.com/docs/products/kb/inde … bleColumns
