내 코드 : 다음과 같다
private Nuage4SchoolDatabaseEntities1 Nuage1 = new Nuage4SchoolDatabaseEntities1();
protected void Page_Load(object sender, EventArgs e)
{
// get info
//set info in the new page - set attribute values to html tag
Button1.Attributes["text"] = "go";
}
protected void Button1_Click(object sender, EventArgs e)
{
ClassroomCreate Create = new ClassroomCreate();
Create.Teacher_id = Page.User.Identity.Name;
Create.Classgroup_Name = TextBox6.Text;
Create.Subject = TextBox1.Text;
Create.Number_of_Students = Dropdownlist1.Text;
Create.Start_Date = calendar1.VisibleDate;
Create.Finish_Date = calendar2.VisibleDate;
Create.Access_Key = TextBox4.Text;
Nuage1.UploadFiles.Add(Create);
Nuage1.SaveChanges();
Nuage1.UploadFiles.Add(Create);는 문제가 될 것으로 보인다. 내가 도대체 뭘 잘못하고있는 겁니까?
