The problem that winformdview cannot be edited

A very depressing thing to remember

When developing with Winform,

If you enable editing for the Datagridview to be deselected

When the project is generated, the ReadOnly of Columns of the Datagridview columis changed to true.

The problem is that the editing of the DataGridView is Enabled Next time, but the ReadOnly of the Columns of the Datagridview is still true and will not change with the ReadOnly of the DataGridView.

The columns that can be edited cannot be edited.

Solution:

When dview enables editing, click Edit column to manually change ReadOnly of the column to False.
