I'm creating a sitepage in designer and need to add a webpart using the existing custom list. But, I'm not able to get any options such as "Data View" in the insert tab. Its seems to be greyed out. I have placed the cursor in the zonetemplate and no luck yet. What may be the cause for this ? I'm the admin user for this site too.
EDIT
This was working fine before. There was some error occurred in one of the custom lists and I have removed it from the server. I have enabled/disabled some features (Publishing,Wiki etc) while doing this. Don't know whether this will affect this greying out somehow. Any idea on this?
