i have tried substituting many of x:name values found in .xaml file something_here when using silver.content.findname(something_here). returns null. want handle lets me play/pause/seek amazon instant video own javascript console? how should procceed?

the app manifest not actual silverlight application, defines assemblies in xap file make silverlight application. silverlight mediaelement trying access defined in xaml file contained in 1 of dll's listed in app manifest, amazon.atvsilverlightplayer.dll start looking. .net reflector inspecting dlls.

referencing mediaelement name fragile approach assigning x:name attribute silverlight elements optional , amazon change @ point. traverse silverlight app visual tree , objects of type mediaelement following approach described here: javascript array of textblock elements xaml file

i had change working me:

    var hasloaded = false;      function onsilverlightload(sender) {         if (hasloaded) {             return;         }         foreachdescendant(document.getelementbyid('silverlightobject').content.root);         hasloaded = true;     }      function foreachdescendant(elem) {         if (elem != null) {             console.log('type: ' + elem.tostring());             if (typeof elem.children == 'object') {                 (var = 0; < elem.children.count; i++) {                     var child = elem.children.getitem(i);                     foreachdescendant(child);                 }             }             else if (typeof elem.content == 'object') {                 foreachdescendant(elem.content);             }         }     }
