I have an ASCX control (CandidateNoteEditor), which is used in an ASPX page. The control has a public read-write property (NetworkerId), which I assign inside the ASPX page, using the "attribute" syntax: <uc:CandidateNoteEditor id="ucCandidateNoteEditor" runat="server" ItemIndex="<%# Container.ItemIndex %>" NetworkerId="<%# GetCandidateId(Container.DataItem) %>" NoteText="<%# GetNotesText(Container.DataItem) %>"></uc:CandidateNoteEditor> When I select Find Usages for the NetworkerId property and press "Show Only Read Usages" the above usage is listed, which is incorrect, because it's actually assigning to the property.
