Question

我的表单上有一个数据网格，它与DataTable绑定我用这个代码

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

每次我点击标题或想要更改组合框时，单元格中的文字会一次又一次地重写。之前从未见过，看（这是第五次点击标题后）

datagrid是readonly，没有什么特别的设置我尝试过刷新方法更新方法更新数据表和其他许多事情，但我放弃了.. 任何帮助将不胜感激

谢谢专利

我不知道你是如何设法设置这个dataGridViewCellStyle30.BackColor = System.Drawing.Color.Transparent;的，但它正在解决你的所有问题，试着改变它。它基本上不会重新填充您的背景，并且会在之前的文本上绘制新文本。将其更改为dataGridViewCellStyle30中的其他颜色。
