c# - Executing javascript in Silverlight with Firefox -

-

i trying execute piece of javascript in silverlight application. pretty simple example have created... single button tries execute line of code...

private void button_click(object sender, routedeventargs e) {    htmlpage.window.eval("alert('hi');"); }

the alert window come freezes firefox, have force quit firefox never comes life.... has ran this??

i thought maybe firefox plugin causing problem have disabled them same results.

the way can work if go about:config in firefox , set dom.ipc.plugins.enabled.npctrl.dll false

any ideas???

well think partially figured out...

i added parameter silverlight hosting page...

<param name="windowless" value="true" />

so whole <div>

 <div id="silverlightcontrolhost">     <object data="data:application/x-silverlight-2," type="application/x-silverlight-2"         width="100%" height="100%">         <param name="source" value="clientbin/javascriptsltrigger.xap" />         <param name="onerror" value="onsilverlighterror" />         <param name="background" value="white" />         <param name="minruntimeversion" value="4.0.50826.0" />         <param name="windowless" value="true" />         <param name="autoupgrade" value="true" />         <a href="http://go.microsoft.com/fwlink/?linkid=149156&v=4.0.50826.0" style="text-decoration: none">             <img src="http://go.microsoft.com/fwlink/?linkid=161376" alt="get microsoft silverlight"                 style="border-style: none" />         </a>     </object>     <iframe id="_sl_historyframe" style="visibility: hidden; height: 0px; width: 0px;         border: 0px"></iframe> </div>
