Allow for bulk edits of the grid/datasource without triggering the change event til complete. Similar to Spreadsheet
In the spreadsheet there is a way to delay repainting til bulk editing is complete. Grid does not have such a mechanism easily accessed, however with a grid with a large number of rows, inserting multiple rows takes a long time as each row insert triggers the change event. It can be worked around but would be better if it was supported like spreadsheet.
