Top article

Introduction


Text Property : you can access or set the item text which is in DropDownList. If you want to access the text of the DropDownList then simply you can use
String var=DropDownList1.items[i].Text; (this is correct)
Here items[i] is directly denote to collection so you can not use 
String var=DropDownList1.items.Text;  ( This is incorrect)
If you want to add items to the DropDownList , simply you can use add method 
DropDownList1.Items.Add("hello");
