Examples
CheckBoxList
In this example, we declare a CheckBoxList control in an .aspx file. Then we create an event handler for the SelectedIndexChanged event. The list contains six optional check box. When the user selects one of them, the page will automatically back to the server, and perform Check subroutine. Items that will traverse control subroutine collection and test the Selected property of each item. The selected item is displayed in the Label control.
