你绑定的是  List <Rs_Sysyem.Models.RS_Person> 之类的吧

Label temp_tab = (Label)e.Row.FindControl("a_status_m");
            //DataRowView temp_dv = (DataRowView)e.Row.DataItem;
Rs_Sysyem.Models.RS_Person p = (Rs_Sysyem.Models.RS_Person)e.Row.DataItem;
            //temp_tab.Text = AttendanceClass.ShowStatus(temp_dv.Row["a_status_m"].ToString());
temp_tab.Text = AttendanceClass.ShowStatus(p.YourPropertyName);

Jinglecat 兄台 我照你的改了还是……

要使用DataRowView好像应该用这个对象
e.Row.NameContainer.DataItem

[Jinglecat]

显然你绑定的不是 DataTable/DataView

[Jinglecat]

你绑定的是 List<Rs_Sysyem.Models.RS_Person> 之类的吧

Label temp_tab = (Label)e.Row.FindControl("a_status_m");
//DataRowView temp_dv = (DataRowView)e.Row.DataItem;
Rs_Sysyem.Models.RS_Person p = (Rs_Sysyem.Models.RS_Person)e.Row.DataItem;
//temp_tab.Text = AttendanceClass.ShowStatus(temp_dv.Row["a_status_m"].ToString());
temp_tab.Text = AttendanceClass.ShowStatus(p.YourPropertyName);
