dynamic scrolling and treetable

Webix JS
1

I’m lost.

myTreeTable.attachEvent(“onScrollY”, function() {
var state = this.getScrollState();
var id = this.getIdByIndex(state.y);
=====> this.getItem(id) is supposed to give me the item in the treatable ???
loadDynamic(id, data);
this.refresh();

state.y is the scroll top position of the view, it can’t be used in the getIdByIndex, that expects numeric index of item, not the view position.

You can try to use Math.round(state.y / item_height) to get the index of top visible item.

Thanks a million ! It works… but finally i changed the approach.
