I don't have an answer to your question. But, it seems to me that it would not be necessary to know when the Data events have 
finished. Isn't it logical to assume that they would be finished at, or close enough to, the time when the loop you use to 
iterate over the dataset is finished?

If you think that is not a safe assumption, perhaps you could use a Timer set to an appropriate value and simply Restart it 
within the Data event.

Or, do your summary processing on the dataset itself and let the gridview fill its data in whatever time it pleases.
