A DevExpress check box list, which is represented by the ASPxCheckBoxList control, is a check box group that provides end-users with the ability to select multiple items.
Data-Bound and Unbound Modes Support
The editor's contents can be generated dynamically by binding the editor to a data source, as well manually populating the control's item collection. When retrieving items from the data source, item characteristics such as the text, value, and image are obtained from specific data fields that can be defined manually or are obtained automatically, providing the data fields named in a specific way.
Flexibly Customized Layout
You can display check box items in several columns, set a direction of items within the editor (horizontal or vertical), and specify whether items are aligned within a table or rendered without any table structure.
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 or set a particular image for each item.
The ASPxCheckBoxList control provides a powerful and seamless way to perform data validation both on the client and server side, allowing you to implement any custom validation logic. If an editor fails validation logic, an error message can be displayed.
Rich Client-Side Functionality
The ASPxCheckBoxList control provides rich client-side API functionality. The main operations that you can perform on the client side are listed below.
- Select and deselect items and respond to selection change.
- Manipulate an editor's availability and visibility.
- Move input focus to an editor and respond to focus getting and leaving.
- Perform editor validation and respond to this action.
