How do I know if a grid has at least one added, updated or deleted row?
You may try to use the events:
onGridReconstructed for “added”,“deleted” rows:
docs.dhtmlx.com/doku.php?id=dhtm … onstructed
onEditCell for “updated” cells:
docs.dhtmlx.com/doku.php?id=dhtm … oneditcell
Also you may use onRowAdded, onAfterRowDeleted events:
docs.dhtmlx.com/doku.php?id=dhtm … onrowadded
docs.dhtmlx.com/doku.php?id=dhtm … rowdeleted
