In v3.4, the SelectAll option from the CheckComboBox will do all that what you want :
-
Call the Command Property's Execute Method and Raise the ItemSelectionChanged Event for every item.
Issue with "SelectedItemsOverride is modified prior to the drop-down opening" is already fixed and included in v3.4. -
The SelectAll checkBox can be checked in the UI and will be updated relative to the other checkboxes. For example, you have 4 items (plus the Select All checkbox) and you check the 4 items => the SelectAll check box will be automatically checked. If 1 of the item is unchecked, the SelectAll checkbox will become unchecked.
In code-behind, You have have access to 2 new methods "SelectAll()" and "UnSelectAll()" which will check/uncheck all items and update the SelectAll checkBox. -
The SelectAll checkBox will react to the items it is related to.
