title: How to access ListView object from current ListView in DetailView on XAF
body: <p>In a DetailView page, I have two ListView. The first one is a GridView which has some information and user can select multiple rows, second ListView is a map that created from IMapsMarker interface. After user selects some rows from first ListView I want to show them on a Map which is second ListView in the same page. So far, I created a ViewController and taking the filtered rows but I could not access the second ListView which is a map. I tried the following code but it didn't work since current ListView is not contain a map.</p>
  
  <pre><code>            WebMapsListEditor webMapsListEditor = ((ListView)View).Editor as WebMapsListEditor;
          if (webMapsListEditor != null)
          {
              webMapsListEditor.MapViewer.ClientSideEvents.Customize = SetMarkers(selectedRows);
          }
  </code></pre>
  
  <p>selectedRows is a list that contain Latitude, Longitude and some other properties. So how to access another list view in a current ViewController and set its properties? Or is there a better way to implement this scenario? I'm using Xaf 18.1 version and Web module.</p>
