1-我创建了一个名为"DoubleBuffer.vb"的模块

1- i created a module named "DoubleBuffer.vb"

2- i add that code in it:

Imports System
Imports System.Reflection
Imports System.Windows.Forms
Module DoubleBuffer
    Public Sub DoubleBuffered(ByVal dgv As DataGridView, ByVal setting As Boolean)
        Dim dgvType As Type = dgv.[GetType]()
        Dim pi As PropertyInfo = dgvType.GetProperty("DoubleBuffered", BindingFlags.Instance Or BindingFlags.NonPublic)
        pi.SetValue(dgv, setting, Nothing)
    End Sub
End Module

事件：

DoubleBuffer.DoubleBuffered(DataGridView1, True)

但是它给了我BLACK Cells

but it give me BLACK Cells

所以，我遇到的问题是什么？

so, what is the problem i faced here?

推荐答案

您不需要为此数量的记录进行双缓冲，其他内容必须继续导致这些问题，而不仅仅是将数据加载到DataGridView。

You should not need double buffering for that amount of records, something else must be going on to cause these issues other than simply loading data into your DataGridView.
