.net - Using VirtualMode on a DataGridView when the number of rows/columns isn't known -

I need to display an unknown length sequence of dictionaries with efficiently unknowable keys in a grid. This sequence is a potential The result of a slow LINQ query that can have any effect.

At first I thought I was looking at, but it seems that the number of rows and columns should be known advances if I tried to add a line and column then the event needs more than Adding it does not work.

Is this possible with VirtualMode? Or do I need to estimate how many rows are visible on the screen and manually rows / columns created? And if so, how can I ensure that a vertical scrollbar is present and when a user uses it, give proper feedback?

"post-text" itemprop = "text">

You will simply notify the grid to update as rows which may be an IBindingList archive. You can populate this collection using LINQ which can be 'N' number during initial load, set certain rows as initial record sets in the archive, say 1000, and then Keep adding rows to the archive, as you repeat your LINQ query.
