Answer 1

I found some way like this:
var editing_row_field2;
....
onItemEditing: function(args) {
editing_row_field2= args.item.field2; },
fields: [{ name: "field2", type: "number"},
{ name: "field1", type: "number",
validate: { validator: function(value, item) {
return editing_row_field2 >= value; },
message: "FIELD1 should be smaller or equal than FIELD2." }
},
{ type: "control", modeSwitchButton: false, editButton: true, deleteButton: false }]

You can access other fields in current row using item argument from validator function
fields: [{ name: "field2", type: "number"},
{ name: "field1", type: "number",
validate: { validator: function(value, item) {
return item.field2 >= value; },
message: "FIELD1 should be smaller or equal than FIELD2." }
},
{ type: "control", modeSwitchButton: false, editButton: true, deleteButton: false }]
