I have Created Data Form web part in SharePoint Designer 2013 and it was working fine. But when i check out the page and check in again it disappears from the page.
Same happens with the List View web part also.
This happens very frequently when i edit the page in SharePoint designer.
Even after appending "?contents=1" to the URL i don't see my web part (refer following image).
Is there anything i need to consider while creating/editing the web part in SharePoint designer OR is it something wrong with my SharePoint Designer ?
Does anyone have any idea how to fix this issue?
Thanks in advance..
