How can I display a certain node only if a session object is set to true?

ie. I want

<siteMapNode url="profile.aspx" title="Profile" >

to be visible only if

Session["DISPLAY_PROFILE_NODE"] = true;

Thanks in advance.

When will you set Session["DISPLAY_PROFILE_NODE"] = true;? Do you base on some kind of role? If yes, then you can use the role attribute in <siteMapNode>. For example, the Admin node only will show if the logon user is in Administrators role.

Hope this helps.

Thank you but I am already aware of the security trimming feature. I want to display it only based on a session property. Thanks.

You really only have 2 choices here:  Filter at the control or filter at the provider

If you filter at the control you should implement the ItemDataBound or NodeDataBound event handlers for TreeView/Menu and remove those nodes as appropriate.  If you need a SiteMapPath to filter this way as well (which it doesn't sound like you do) you would need to handle this in a SiteMapResolve handler.

If you filter at the provider you need to create a custom provider and remove this node in code that overrides IsAccessibleToUser(). 

What you SHOULD NOT do under any circumstance is remove the node from the provider.  That will corrupt the datastore for other users accessible the information.
