            一直显示这个错误：其他信息: A primary key field specified via the KeyFieldName property is not found in the underlying data source. Make sure the field name is spelled correctly. Pay attention to the character case.

            我主键也设置了   为什么还显示这个  

Answer 1

A primary key field specified via the KeyFieldName property is not found in the underlying data source. Make sure the field name is spelled correctly. Pay attention to the character case.

错误的大概意思是 你没有通过 “KeyFieldName” 属性来 设置主键，并且确定主键 拼写正确。
