How to change the OK/Cancel buttons to redirect back to Parent/Child listDescription
Cause
This happens because the native upload page cannot redirect back
Resolution
You have to create a CustomUpload.aspx page in SharePoint Designer as an EDIT form (New Form will not work) and used it as the New Form URL in the webpart for the Parent/Child qListView.
Now the OK and Cancel buttons will bring you back to the source page.
