在大数据填充的DataGridView性能下降

问题描述

我使用的BindingSource控制，以填充DataGridView控件。大约有1000个以上的记录填充它。我使用线程这样做。 DataGridView的执行在这种情况下很慢。

I am using a BindingSource control to populate datagridview control. There are around 1000+ records populating on it. I am using threading to do so. The datagridview performs very slow in this case.

我试图DoubleBuffered属性设置为true，RowHeadersWidthSizeMode禁用，AutoSizeColumnsMode无法比拟的。但是还是一样的行为。

I tried to set DoubleBuffered property to true, RowHeadersWidthSizeMode to disabled, AutoSizeColumnsMode to none. But still the same behavior.

请帮我在这。事先我怎么能提高电网的性能。

Please assist me in this. How can I improve the performance of the Grid.

谢谢，

推荐答案

如果你有一个巨大的行量，像10 000多，

If you have a huge amount of rows, like 10 000 and more,

要避免性能泄漏 - 执行以下操作数据绑定之前：

to avoid performance leak - do the following before data binding:

dataGridView1.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.EnableResizing; //or even better .DisableResizing. Most time consumption enum is DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders

// set it to false if not needed
dataGridView1.RowHeadersVisible = false;

在数据绑定您可以启用它。

after data binded you may enable it.
