推荐答案

正在填充多少行/单元格-100英寸，数百万? 800,000行的DataGridView也有类似的问题.我的行越多，加载速度就越慢.我从Microsoft找到了一篇有关提高具有大记录集的DataGridViews性能的文章(实际上，是Code Project中的清单推荐).它表示要避免更改列中所有单个单元格的属性；它还建议您尽可能使用虚拟模式.

本文位于"http://msdn.microsoft.com/zh-cn/library/ms171621.aspx"，标题为"Windows窗体DataGridView控件中的性能调整".

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...
