Yes, you can set this in the template, or you can set the MasterPageId
property in the widget by clicking on Edit>>Advanced>>Home > ControlDefinition > Views > EventsFrontendEdit
to the Id
of the page you want to set.
Note however, that both settings will replicate an already existing functionality in the Events widget designer to specify single event items to open in another page (please see attached screenshot). My point is that even though you might set the All Events link to a different page, once you click on all items you will be redirected to the desired page, but if you click on an event on that page, this single item will be opened automatically in the same page, unless you also set the
<sf:DetailsViewHyperLink TextDataField="Title" ToolTipDataField="Description" runat="server" />
in the template for ListItems
I hope this information helps. If you need any further help accomplishing the desired functionality, please do not hesitate to contact me.
