I want to add a ‘Select One’ option to a drop down list bound to a List<T>.
Once I query for the List<T>, how do I add my initial Item, not part of the data source, as the FIRST element in that List<T> ? I have:
// populate ti from data List<MyTypeItem> ti = MyTypeItem.GetTypeItems(); //create initial entry MyTypeItem initialItem = new MyTypeItem(); initialItem.TypeItem = 'Select One'; initialItem.TypeItemID = 0; ti.Add(initialItem) <!-- want this at the TOP! // then DropDownList1.DataSource = ti;
Use the Insert method:
