CheckedListBox | marshal by reference, disposable |
System.Windows.Forms (system.windows.forms.dll) | class |
This control, derived from ListBox, provides a
list of items with a check beside each one, providing an alternative
selection mechanism. It extends the base listbox by providing you
with two collection accessors:
CheckedItemCollection, which returns the set of
all the checked items in the list, and
CheckedIndexCollection, which returns a set
containing the index of each checked item in the list. You can then
use the GetItemChecked() and
GetItemCheckState() methods to determine the
actual check state for the item.
You can support either two- or three-state checkboxes, and
ThreeDCheckBoxes, or flat ones. You can also
choose whether the item is checked when it is selected, or whether
the checkbox itself must be clicked.
