I am populating a ComboBox from an API. The API returns paginated data and there could be 100s of records. I dont want to load on the records at once so I want to load let’s say 25 records then when the user scrolls to the end of the ComboBox load the next 25 and so on. The poblem I am having is that I cannot detect the scroll even and call the api for the next set of records. Here is what I’ve tried so far.
