Field renderer was working fine on mvc but now we moved to web pages, and i am converting my layouts & renderings to webpages but field renderer are not working in page editor mode but in published mode looking fine. page editor screen shot is attached.
Field rendered as
<sc:Text ID="Title" Item="<%# ((Sitecore.Data.Items.Item)Container.DataItem) %>" Field="Navigation Title" runat="server" />
and
<%# FieldRenderer.Render(Container.DataItem as Sitecore.Data.Items.Item, "Navigation Title") %>
tryied both but same result :) any help would be appreciated.
I have av vague memory of seeing this error before. If I remember right, the problem was that Sitecore couldn't do all its Page Editor magic properly by inserting scripts etc into the html header and body. It's worth I try to just verify that your layout forms a proper html document and having the head and a form accessible from the server, such as this:
<!DOCTYPE html>
<html>
<head runat="server">
</head>
<body>
<form runat="server">
</form>
</body>
</html>
I was a long time ago I used webforms with Sitecore, so I don't remember exactly what components Sitecore hooks into in order to make the editor works, but having a page structure as above should be good to go.
Hope it helps
