In MOSS 2007 and SharePoint 2010 you can reroute the user to a custom page after they complete uploading documents to a document library to by changing the source parameter in the query string URL like what’s shown below:
However be sure to remove an additional parameter &IsDlg from the query string for this to work.
This also holds true for uploading multiple documents in SharePoint MOSS 2007. But in SharePoint 2010 we are using an ActiveX control that is not allowing users to be routed to a custom page after uploading multiple documents.
In the SharePoint 2010 UploadEx.aspx page calls the UploadCtl ActiveX and hardcodes the URL to the library URL followed by AllItems.aspx. Hence varying the source parameter doesn’t work in this scenario.
Create a custom upload page.
Here we pass the rerouting parameter to a web UploadCtl via a hidden field. Change the value of this parameter to whatever is required by you.
