ASPxCheckBoxList Overview

The ASPxCheckBoxList editor is a check box group that provides end-users with the ability to select multiple items.

ASPxCheckBoxList supports both data-bound and unbound modes. This means that its contents can be generated dynamically by binding the editor to a data source, as well as manually populating the control's item collection.

Selection

The items selected within ASPxCheckBoxList can be determined by iterating through all list items and inspecting an item's ListEditItem.Selected property, or by using specific properties declared at the editor level (ASPxCheckBoxList.SelectedItems, ASPxCheckBoxList.SelectedIndices, ASPxCheckBoxList.SelectedValues). You can easily select/unselect all editor items by using the SelectAll/UnselectAll methods that are available on both the server (ASPxCheckBoxList.SelectAll/ASPxCheckBoxList.UnselectAll) and client (ASPxClientCheckBoxList.SelectAll/ASPxClientCheckBoxList.UnselectAll) sides.

Layout Customization

The ASPxCheckBoxList layout is flexibly customized. You can display check box items in several columns (ASPxCheckListBase.RepeatColumns), set a direction of items within the editor (horizontal or vertical through the ASPxCheckListBase.RepeatDirection property), and specify whether items are aligned within a table or rendered without any table structure (ASPxCheckListBase.RepeatLayout).

Custom Item Images

The ASPxCheckBoxList editor allows you to specify images for its items. You can specify one image for all items within the control using the ASPxCheckListBase.ItemImage property, or set a particular image for each item using item's ListEditItem.ImageUrl property.
