Getting selected items from a SharePoint:ListViewByQuery webpart, embedded in a Visual Webpart

Question

I am having trouble getting the selected items from a ListViewByQuery webpart, using the Client Object Model (JavaScript).

Code (server-side)

<SharePoint:ListViewByQuery runat="server" ID="lvbqMyNews" Enabled="True" DisableSort="False" DisableFilter="False" />

Code (client-side)

var context = SP.ClientContext.get_current();
SP.ListOperation.Selection.getSelectedItems(context);

//returns: [] when anything is selected.

I've tested the same code when going to a normal List in SharePoint, where it gets the selected items perfectly.

Problem

I am not able to get the selected items from the Embedded ListViewByQuery webpart (User control), when I have selected from a ListViewByQuery in a Webpart where I have added the control myself.

If I attempt the same operation on a normal list, then there is no problem getting the list of items. It seems like the Client Object Model is not aware of the ListViewByQuery webpart..

I think your syntax for the Client Object Model might not be correct. It should be:

var context = SP.ClientContext.get_current();
SP.ListOperation.Selection.getSelectedItems(context);

It's SP.ClientContext and not SP.Context.

Also, you could try using the XSLTListViewWebPart instead of ListViewByQuery webpart. I have used it successfully before, with the SP.ListOperation namespace.
