L_ILN_ITEMUNSEL

Sent when the user unselects one or more items in the ImageList Control.

Comments

Sent when the user unselects one or more items in the ImageList Control. pItemSel contains information about the item that was unselected.

The parent window of the control receives this notification message through the WM_COMMAND message.

Note: If you are subclassing the ImageList Control window, you can use the L_ILM_ITEMUNSELECTED message to get item unselection notifications.
