Inline editing is not supported for all iSheet column types (such as Lookups, Joins, Calculations, and Rich text HTML in MLT). It is also important to note that, for large-scale iSheets or views with high record volumes, bulk editing and dashboard loading performance may be affected. As a best practice, limit iSheet views to 200 columns and 10,000 records. To optimise performance, create multiple iSheet views and use them within table panels to better manage the load.
