asp.net - Programmically set JWPlayer to play file from database -


i have querystring on page load use filename , thumbnail image jwplayer. not getting filename or thumbname, however. there must reasson why can't on aspx page, vb code behind.see code:

code behind (vb): protected sub page_load(sender object, e system.eventargs) handles me.load     dim videoname string = request.querystring("filename")     dim thumb string = request.querystring("thumb") end sub

and need these string variables .aspx page jwplayer script, not 

.aspx: <div id='container'></div> <script type="text/javascript" src="~/player/jwplayer.js</script> <script type="text/javascript">         jwplayer("container").setup({                             file: videoname,             flashplayer: '~/player/player.swf',             volume: 35,             width: 480,             height: 270,             skin: '~/player/skins/skin.zip',             image: thumb,                         }) </script>

this ho solved it

code behind (vb):  protected sub page_load(sender object, e system.eventargs) handles me.load    dim videoname string = request.querystring("filename")    dim thumb string = request.querystring("thumb")    dim dur string = request.querystring("duration").tostring()       txt1.text = "~contents/published/" & videoname.tostring()     txt2.text = "~/contents/thumbs/" & thumb.tostring()     txt3.text = dur.tostring()  end sub

now value of query string jwplayer javascript, had add javascript function inside jw script , called codeaddress(). kind of documentation not found on longtail website or tutorials or anywhere else on internet have found. 

.aspx: <script type="text/javascript">         function codeaddress() {             var dootoo = document.getelementbyid('<%=txt1.clientid%>').value;             var doothree = document.getelementbyid('<%=txt2.clientid%>').value;             var doofour = document.getelementbyid('<%=txt3.clientid%>').value;             jwplayer("container").setup({                 duration: doofour,                 file: dootoo,                 flashplayer: '~/player/player.swf',                 skin: "~/player/skins/newtubedark.zip",                 volume: 35,                 width: 685,                 height: 385,                 image: doothree,              })         }         window.onload = codeaddress;     </script> <asp:textbox id="txt1" runat="server" style="display:none;"></asp:textbox>     <asp:textbox id="txt2" runat="server" style="display:none;"></asp:textbox>     <asp:textbox id="txt3" runat="server" style="display:none;"></asp:textbox>
