Need a simple way to have only one mode per link with an option

[Cal Who]

I use items like the following to display links in an iFrame within my page.

<asp:TreeNode NavigateUrl="http://en.wikipedia.org/wiki/Church"
Target="LinksFrame" Text="Wikipedi Item on Church"></asp:TreeNode>

I can envision situations where the iFrame might be too small and the user
would like to display in another window.

I'd like to have a check box to allow that option.

On way I could implement is to have two statements for each link and use the
check box to select the appropriate one.



Is there a simple way to have only one statement per link and change the
target?





Thanks
