推荐答案

设置DataGridView Coulumn的宽度
您首先需要用必填数据填充它.如果它没有任何数据，则肯定会引发此异常.首先设置DataGridView的数据源，然后添加代码以设置宽度.此外，如果您的数据库表中没有数据，那么也会发生此问题.
使用尝试捕获异常"处理可删除此异常.
另外，也可以用两行代码代替编写此代码，
DataGridView1.Columns(0).width = 50
试试这个

To set the Width of your DataGridView Coulumn
you First need to fill it with the Required Data.If it will not have any data it will surely throw this exception.Set the Datasource of DataGridView First, then add the code to set the width.Also if in your Database table there is no data then also this problem will happen.
Use Try Catch Exception handling to remove this exception.
Also in place of writing the this code in two line you can reduce it to
DataGridView1.Columns(0).width =50
Try this
