myEntities dc = new myEntities();
...
//i show the table data to user
mainSearchedData = dc.Invoice.ToList();
gvMain.DataSource = mainSearchedData;
//then i change some data in the table(Somewhere else in the code) and save
//it
dc.SaveChanges(); //(the change is successfull i can se it in SSMS)
//since if i just use the gvMain.datasource set it wont load the changes
//that has been made in the tabel i want to reload
dc.Entry(dc).Reload(); <-- This is causing the error
“System.InvalidOperationException：'实体类型 myEntities 不是当前上下文模型的一部分。”
我愿意提供一个没有Reload()如何使实体框架实际加载修改数据的方法的解决方案
