TreeGrid expandRecords question

[Hirn]

I have 20 applications on SmartGWT that I am rewriting on REACT. And in order not to completely rewrite the logic of applications, I try to borrow a lot from SmartGWT.

Yes, except that in SmartClient, you would not actually add the handler that way, but rather in an isc.ClassName.create({ ... }) block. It would be invalid to assign directly like that.

Why do you ask, troubleshooting something?

in SmartGWT, I have an event handler

listGrid.addRecordExpandHandler(new RecordExpandHandler() {
            public void onRecordExpand(RecordExpandEvent event) {
                ListGridRecord record = event.getRecord();
                if(!condition) {
                    event.cancel();
                }
            }
        });

will such a definition be an analogue of this event handler in SmartClient?

    listGrid.expandRecord = function(record) {
        if(condition) {
            this.Super("expandRecord", record);
        }
    }

Yes - canExpand controls whether the end user can do expansions. You as the developer can still expand whatever records you want.

if I call expandRecords in the TreeGrid, even those nodes with the canExpand=false attribute are expanded. Is this how it should be?
