Joe,

I was able to make this work, but only with code-behind and I am unsure why, but wanted to pass this along:

with this link below on the page and no code-behind properties it will always show logged in or not:

<asp:HyperLink ID="lnkEdit" runat="server" Visible='<%# IsEditable %>' Text="EDIT" NavigateUrl="http://www.domain.com" />

I also had the "IsEditable" display in a label so I could verify TRUE or FALSE -  LblInfoUser.Text = Convert.ToString(IsEditable);

TRUE or FALSE the link showed up.

-----------------------------------

with this link below on the page and the properties set with code-behind it will work correctly:

<asp:HyperLink ID="lnkEdit" runat="server" />

Code Behind:

lnkEdit.Visible = IsEditable;
lnkEdit.NavigateUrl = "http://www.domain.com";
lnkEdit.Target = "_blank";
lnkEdit.Text = "EDIT";

thanks for the clarification - now it is all starting to make sense.
