Actual Results

Expected Results

BeginUpdate doesn't work at all when datasource items get changed. Even though BeginUpdate is called the grid takes awfully lot of time to process changes.

Hello Miha,

The BeginUpdate method doesn't block data notifications. We will add BeginDataUpdate / EndDataUpdate methods similar to the XtraGrid. Thank you for drawing our attention to this issue.

Thank you,
Nick

Nick: Yes, obviously :-)

In the meantime, here is a workaround:

Miha,

Thanks for your article. Your solution is good. I'd also call the OnDataManager_ListChanged method with the ListChangedType.Reset parameter from EndUpdate in the inherited class.

Thank you,
Nick
