SMART datagrid v.1 > Classes > OperateOptions
If it is true, the user can do row grouping by dragging the column header cell to group panel.
Although you can set DataColumn.groupable property to specify whether individual grouping of each column is possible, you should specify this property value as true first.
Defaults to true.
grid.setOptions({
operate: {
groupingEnabled: true
}
});
grid.setOperateOptions({
groupingEnabled: true
});
grid.operateOptions().setGroupingEnabled(true);
