Can I add array of items to grid that will cause only one refresh ?

[Maciej]

After some investigation I discovered that when you add an array of items do grid bound datasource, the grid will refresh (rebuild from scratch) for every new item. In some cases that a major performance hit. Can I add array of items to grid that will cause only one refresh ?

Hello Maciej,

A possible solution is to unbind the change event handler of the dataSource from the Grid before adding the items. For example, check this KB article:
