Can you show us the selected index change function of the dropdown?

How many rows/cells are being populated -- 100's, millions? I had a similar problem with an 800,000-row DataGridView. The more rows I had, the slower it loaded. I found an article (actually, recommended by a listing in Code Project) from Microsoft on improving performance of DataGridViews with large recordsets. It says to avoid changing the properties of all individual cells in a column; it also recommends using Virtual Mode if possible.

The article is at "http://msdn.microsoft.com/en-us/library/ms171621.aspx" and is titled "Performance Tuning in the Windows Forms DataGridView Control."

Hope this helps...
