Introduction:
Here I will explain ListBox in ASP.NET. Discription
The ListBox
control is used to create a single- or multi-selection drop-down list.Each selectable
item in a ListBox control is defined by a ListItem element! The ListControl control
covers all the base functions for list controls. Controls that inherits from this
control include the CheckBoxList, DropDownList, ListBox, and RadioButtonList controls.
