Checked/unchecked menu items in Windows Forms ContextMenuStrip (ContextMenuStripEx)

This support will help users to easily acknowledge the selected menu item by using the check mark. The Checked property indicates whether a check mark should appear before the text of the menu item or not. The CheckState property specifies the exact state - checked or unchecked which needs to be set either statically. On runtime, user need to toggle the state manually through the Click event of the menu item.

NOTE:

  1. This feature is not applicable for combobox and textbox.
  2. This feature will be applied only if ShowCheckMargin property of ContextMenuStripEx is set to true.

Below code snippet will explain the check state of the menu item.
