Question

Any suggestions on how to improve DataGridViewComboBoxColumn performace with large item sets?

I’ve got a DataGridView with several columns of type DataGridViewComboBoxColumn. I’m databinding those combobox columns to a rather large collection (10k+ items). As a result it’s very slow to display the items (when i click on the down-arrow button on a cell it takes about 10 seconds to display the items).

I’ve tested the same collection of items with a standard ComboBox control, and it works really fast.

Any ideas?

Thanks.
