Fast Data grid

[Vijendra Malhotra]

What is the fastest way to refresh contents in a data grid. I would
like to populate a grid based on message from a EMS queue with a
frequency of about 100 messages per second.
what is the best way to do this?

Vijendra,

I would queue up the messages and update the grid in intervals...
Having the grid update when every time a message comes in with that kind of
frequency is really going to bring the repainting to a crawl.

I would queue the changes to the data somewhere and then have a timer
fire in intervals to update the grid.

Hope this helps.

Thanks.
But is there no grid control available that will do this for me. We
would like to update the grid without any real delays if possible.
Also is it better to use a databound grid for this?

But who is able to read the changes of the grid that "changes" (you said
refresh, right?) every 10 mSec's?
I guess nobody, so, while it's possible to update a grid at this rate , it
makes no sense at all to do this.
