推荐答案

看看DataGridViewRowCollection

Take a look at the DataGridViewRowCollection methods[^] and see if one of the Insert() methods will do what you want. For example, "Insert(Int32, Int32) Inserts the specified number of rows into the collection at the specified location."

简短的答案是-您不能.

长答案取决于在这样的Q/A论坛中无法令人满意地回答的太多事情.

如果将DataGridview绑定到数据集，则可以独立于DGV向数据集添加新记录，并且如果对索引进行了有利的设置，则新行将出现在DGV中的正确位置.

The short answer is - you can''t.

The long answer depends on too many things to be satisfactorily answered in a Q/A forum like this.

If your DataGridview is bound to a DataSet you can add a new record to the dataset, independently from the DGV, and if your index(es) are set favourably the new row will appear in its correct place in the DGV.
