【问题描述】：
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。没见过，看（这是第五次点击标题后）
数据网格是只读的，没有什么特别的设置我试过 刷新方法 更新方法 更新数据表 还有很多其他的东西，但我放弃了.. 任何帮助将不胜感激
谢谢 帕特

【问题讨论】：
-
这是否是 OwnerDrawn DataGridView。你玩过单元格绘制吗，看起来DataGridView单元格的PaintBackground根本没有被调用。
-
这是标准网格。我不使用任何绘图事件。我使用这些事件：EditingControlShowing、DataBindingComplete、DataError、MouseMove
-
您能否再发布一些代码，尤其是在您设置 DataGridView 时
-
我可以在这里附加附件吗？
-
我认为你不能，但你可以编辑你的问题，它也将帮助其他人为你找到解决方案。只需粘贴初始化代码。
