为什么 DataGridView 上的 DoubleBuffered 属性默认为 false，为什么它受到保护? [英] Why does the DoubleBuffered property default to false on a DataGridView and why is it protected?

问题描述

我们遇到了 DataGridViews 的性能问题，其中重绘速度非常慢，并找到了解决方案 此处 创建派生类型并在控件上启用双缓冲.(派生类型是必需的，因为 DoubleBuffered 属性是受保护的)

We had a performance issue with DataGridViews where the redraw was horridly slow and found the solution Here to create a derived type and enable double buffering on the control. (Derived type is necessary since the DoubleBuffered property is protected)

将 DoubleBuffered 属性设置为 true 似乎没有任何缺点.

It doesn't seem like there's any drawback to having the DoubleBuffered property set to true.

推荐答案

我认为最好的解决方案:

I think its best solution:

typeof(DataGridView).InvokeMember(
   "DoubleBuffered", 
   BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.SetProperty,
   null, 
   myDataGridViewObject, 
   new object[] { true });
