GridView1.DataSource = Sabt;
GridView1.DataBind();
Sabt
seems to be single object. To bind DataGrid you need to have collection like List<JadvalSabtenam >
or BindingList<JadvalSabtenam>
Try that:
List<JadvalSabtenam > dataSource = new List<JadvalSabtenam> {Sabt};
GridView1.DataSource = dataSource;
GridView1.DataBind();
Reason for that is: What Grid should do with single object? When it’s collection each item is corresponding to one row, and each property to column which makes perfect sense.
