Is it possible to refresh a related items control programmatically

[AlexZver]

Dear Andy,

Unfortunately, there is no such option to refresh the Related Items control separately while using CAML query. As a workaround, you can try to utilize the filtered view.

Sorry to bring this up again, but is there any progress on this?

Dear Andy,

Related Items utilizes default MS List View, and uses default SharePoint scripts, there is not much we can do here. These are List View limitations.

You can try some other options to make requests to the List, and present the data. For example, as the client did here - viewtopic.php?f=1&t=1956&p=6145#p6145
