The CheckStateChanged event notifies your application that user changes the checkbox state. Use the HasCheckBox property to associate a checkbox to the editor. Use the CheckState property to retrieve the state of the editor's checkbox. The PartialCheck property specifies whether the checkbox of the editor allows two ( unchecked, checked ) or three states ( unchecked, checked and partial-checked ).

The following sample associates a check box to the editor and prints the state of the check box when user clicks the editor's checkbox area.

Private Sub Editor1_CheckStateChanged()
    With Editor1
        Debug.Print "The user changes the state of the editor's checkbox to " & .CheckState
    End With
End Sub

Private Sub Form_Load()
    With Editor1
    
        .EditType = DropDownList
        .AddItem 1, "One"
        .AddItem 2, "Two"
        
        .HasCheckBox = True
        
        .Value = 1
    End With
End Sub
