I have a DataGrid, with several columns. One of them is DataGridViewComboBoxColumn
. I have a lot of items in this column - more than 1000 - and I need all of them. So grouping is not an option - all items must be there, users must be able to select from all.
The problem is, DataGridViewComboBoxColumn
becomes painfully slow, when number of items is about 1000, and above. This issues is well known to Microsoft, it dates back to Visual Studio 2005: http://connect.microsoft.com/VisualStudio/feedback/details/117024/datagridviewcomboboxcolumn-responds-very-slow-compared-with-the-stand-alone-combobox-control
The problem is still present in Visual Studio 2010. Any ideas how to solve this?
