推荐答案

您不能禁用此命令.将DGV绑定到数据源后，将对数据源进行所有更改.在这种情况下，是一个数据集.除非您告知更改，否则更改不会提交到支持的数据库.

现在，DataSet/Table类维护一个列表，该列表对对象以及填充Set/Table时的原始值进行了更改.因此，如果要放弃更改，只需在数据集/表上调用RejectChanges.

You can''t disable this. Once you bind a DGV to a datasource, all changes are made to the datasource. In you''re case, a DataSet. Changes are NOT commited to the backing Database until you tell it to.

Now, the DataSet/Table classes maintain a list of changes that were made to the object as well as the original values when the Set/Table was Filled. So, if you want to abandon changes, you just need to call RejectChanges on the DataSet/Table.
