I have a form that contains two elements: a CheckedListBox
and a CheckBox
. The CheckBox
, which is called SelectAllCheckBox
, is used to check/uncheck all items in the CheckedListBox
. I achieve this via a CheckedChanged
event handler associated with the SelectAllCheckBox
, so that when it is checked, all items in the CheckedListBox
are checked, and vice versa. This works fine.
I also have code that unchecks the SelectAllCheckBox
when the user unchecks one of the CheckBoxes in the CheckedListBox
. For example, if the user checks the SelectAllCheckBox
, and then unchecks one of the items, the Select All CheckBox
should be unchecked. This is achieved via the CheckedListBox.ItemChecked
event handler. This also works fine.
My problem is that when the SelectAllCheckBox
is programatically unchecked (as in the above scenario), its event handler causes all items in the CheckedListBox
to become unchecked.
I'm sure others have run into my issue; is there an elegant workaround?
