推荐答案
检查页面定义:在GridView1定义中的某个位置具有
Check your page definition: somewhere in your definition of GridView1 you have
DataSourceID="String"
要么删除它,要么从您的Page_load方法中删除Load_GridData调用.
Either remove it, or remove the Load_GridData call from you Page_load method.
从GridView1定义中删除DataSourceID属性
Remove DataSourceID attribute from GridView1 definition
