In my application when user clicks on an audio audio id is retrived in page load and this audio id should be passed to multiple tabs in the browser because i had added an chrome extension which controls the audio in the previous tab from multiple new tabs on button click but i need to control it on keydown event from multiple new tabs if i pass the audio id to all the tabs can i control it using keydown event or how can i control the audio in main tab from multiple new tab using keydown

protected void Page_Load(object sender, EventArgs e)
if (Session["uid"] == null)
adm = new Admin();
ID = Request.QueryString["ID"];

Here i am getting audio id on page load and this id should be retrived and passed to the newly opened tabs in browser,by passing in this way can i control the audio from multiple tabs using keydown

aspx code-

<asp:TemplateField HeaderText="Play Audio File" ItemStyle-Width="200px" ItemStyle-HorizontalAlign="Center" >
<audio controls="controls" id="player">
<source src='<%# Eval("audio") %>' />
your browser does not support the audio element.</audio>

 Replace thew above with the below.


Since in querystring the parameter is "Id" not "ID".
