Getting the warning in my code and not sure how to clean it up properly.
Warning	2	WithEvents variable 'UniqueID' conflicts with property 'UniqueID' in the base class 'Control' and should be declared 'Shadows'.	

Open in new window


This came in shortly after I added
<asp:HiddenField id="UniqueID" runat="server" value=""/> in my default page, and
 If Not IsPostBack = True Then
            Dim GuidString As String = Guid.NewGuid.ToString
            Session("HiddenKeyString") = GuidString
            UniqueID.Value = GuidString
        End If

Open in new window

in my code behind.  I've used this in another project without any additional steps, so I'm unsure why it's causing an issue now.

You should change the name because UniqueID is a property for the Control Class in ASP.NET.

That's because the control class which is derived by hiddenfield already has a property called uniqueid. Change the id of your hidden field to something else and it will be fine.

Consider me a beginner... what do you mean it's a property for the control class?  Have I duplicated something that's embedded natively?

Exactly.

The ASP.NET Page class is a derived class from the Control class, and UniqueID is a property of the Control class.  That means that that property also exists on the Page class.

You added a control to the page, and named it UniqueID also.  Now there is a naming conflict.  

If you give your control a new name, the warning will disappear.

All asp.net controls are derived from the control class, the control class already has a property/attribute called UniqueId.

The control class defines the properties, methods and events shared by all asp.net server controls.

Control Class

UniqueId property of the Control Class
