css friendly adapters headache

Question

Im using the css friendly adapters from codeplex with sharepoint.

It appears to be working although when i go to "manage content and structure" page the page returns an error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).   at System.Web.UI.ControlCollection.Add(Control child) 
   at CSSFriendly.TreeViewAdapter.SaveAdapterViewState() 
   at System.Web.UI.Control.SaveViewStateRecursive() 
   at System.Web.UI.Control.SaveViewStateRecursive() 
   at System.Web.UI.Control.SaveViewStateRecursive() 
   at System.Web.UI.Control.SaveViewStateRecursive() 
   at System.Web.UI.Page.SaveAllState() 
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

any ideas on how to fix this?

Answer 1

I've tried it before and failed miserably. The Adapters DON'T play nice with some of the treeviews used by SharePoint.

See the comment by the author of a walkthrough here:

His comment:

As the person who wrote the walk through you linked to on The Mossman's blog I think its important to post some followup lessons I've learned -- mainly using the CSS Friendly Adapters will cause problems with some of the pages (Manage Content and Structure is one that comes to mind). My preferred method these days is to use the Telerik navigation controls. Its relatively easy to style, cheap, and easy to implement. SharePoint MVP Andrew Connell wrote a great white paper on using the Telerik controls and posted about it on his blog.

Answer 2

I use the control adapters but only where I really need them.. I should think the "manage content and structure" page doesn't need them?
