Next question is related to the previous question, so I should probably add a little background. I'm looking for the fastest way to populate a fairly large grid (Not huge, perhaps 10-15 columns, 20k rows max) and support:
a) dynamically changing data
b) dynamic grid formatting based on those data changes
c) complete flexibility over grid styling.

The nearest example I can find is the trade grid example, but I don't want the flashing business, it's more time based than that. A cell will colour as it ages.

Which leads to the next question, is there a way to tell the grid to requery for the current formatting info? I.e. have the grid reraise QueryCellStyleInfo .?

So I like the idea of the grouping grid and the way it binds to a virtual IBindingList, If I change the data in my virtual list, I can wire it up to QueryCellStyleInfo which will query every time a cell is changed? Is that configurable?

Finally, do I need to do anything to make it work as a virtual grid? There was a setting on the grid engine I think for that? Not sure.

Any advice would be appreciated.

Ditto. The query event is reraised once the data changes.

Hi Dito,

We regret for the delay getting back to you.

Please refer to the following our sample browser sample which illustrates how to trigger one time the QueryStyleInfo event.

Let me know if you have any further concerns.
