我的表单上有一个数据网格，它与 DataTable 绑定我使用此代码

public void SetDataSource(DataTable dt)
    {            
        dgr.DataSource = null;
        dgr.AutoGenerateColumns = false;            
        dgr.DataSource = dt;                 
    }

每次我单击标题或想要更改组合框时，单元格中的文本看起来都会一次又一次地被覆盖。以前没见过，看（这是第五次点击标题后）

在此处输入图像描述

数据网格是只读的，没有什么特别的设置我尝试了刷新方法更新方法更新数据表和许多其他的东西，但我放弃了..任何帮助将不胜感激

谢谢帕特

我不知道你是如何设法设置这个 dataGridViewCellStyle30.BackColor = System.Drawing.Color.Transparent;的，但它会造成你所有的问题，试着改变它。它基本上不会重新填充您的背景，并且会在前一个文本上绘制新文本。将其更改为 dataGridViewCellStyle30 中的其他颜色。
