But I can not implement "SelectionModel" on this model. For example, I want to select first record and last record.For now, If I select the first record and scroll to down then, I can not keep selections because the model is changed by scrolling.
How is the model changed by scrolling, exactly?The issue with selection is that you need an valid index representing the last entry. So, you may lazy load the model data (based on views' requests), but the row count has to be accurate immediately. More than doable, anyhow.
