A Object that specifies the item’s value

The Value property specifies a value associated with an item. When an item is selected in a list editor, its value is assigned to the editor’s ASPxEdit.Value property.
Note
For the list editors (such as the ASPxComboBox, ASPxListBox, ASPxCheckBoxList, and ASPxRadioButtonList) to function properly, values of all list items in their Items collection should be unique. There should not be two or more list items with the same value of the ListEditItem.Value property.

function OnComboBoxSelectedIndexChanged(s, e) {
var item = s.GetSelectedItem();
popup.SetContentHTML(
"Selected item changed:
" +
" <strong>text=</strong>'" + item.text + "'
" +
" <strong>value</strong>=" + item.value + "
");
popup.ShowAtElementByID("comboPopupAnchor");
}
