Use the sortedList class to establish sorted DropDownList
Sortedlist
Class is similar to
Hashtable
with
ArrayList
Mixed mix. Like HashTable, sortedList is also based on
IDictionary
Interface; therefore, each element of sortedList is a key and value pair. SortedList provides a method that only returns a key list or only return value list. Like ArrayList, sortedList is an element sequence. It is indexed and is sorted according to a particular comparator. SortedList in all
Collectes
The class is unique, and each element can be accessed in three ways: use the key, value, or index.
Use sortedlist if you want a collection of saver / value pairs and requires the flexibility of the index list. -------------------------------------------------- ------------------------------------ Example:
SortedList SL
=
New
Sortedlist (); sl.Add (
"
Item
"
,
"
1
"
); Sl.add
"
Item 2
"
,
"
2
"
); Sl.add
"
Item three
"
,
"
3
"
); Sl.add
"
Item
"
,
"
4
"
);
//
Bind DROPDOWNLIST
DROPDOWNLIST1.DATASOSOURCE
=
SL; DropDownList1.DataValuefield
=
"
Value
"
DROPDOWNLIST1.DATATEXTFIELD
=
"
Key
"
DROPDOWNLIST1.DATABIND ();
