Progress Telerik UI for WinForms

Checked List at Your Fingertips
RadCheckedListBox is an enhanced alternative to the standard Windows Forms CheckedListBox control. It uses RadListView as a foundation, so it benefits from its existing functionalities, which are now extended, and provides a list, icons or grid-like entries with checkboxes. A few of those are:
- Item Editing
- Filtering
- Sorting
- Grouping
- Item Size and Customization
- Exporting
For the full set of features, check out the RadListView page.
Check Modes
The control features three useful CheckOnClickMode options:
- Off: Click on the checkbox to toggle the CheckState
- FirstClick: Click anywhere on the item to toggle its checkbox
- SecondClick: Click on a selected to toggle its checkbox
You can also select one or more items and press space to toggle their CheckState.

We have also exposed a convenient API to check/uncheck all items or to check/uncheck the selected items, to cover any scenario.
CheckBoxes Alignment

Easily change CheckBox alignment with simple property settings, to accommodate all supported views.
Data Binding

As an inheritor of, RadCheckedListBox inherits RadListView, extending its functionality to provide a better way to bind your RadCheckedListBox checkboxes to a data source. The CheckedMember is responsible for several types of data to which the check state can be bound, including Boolean, Numeric, ToggleState, CheckState and String.
