I have the following Code on test.ascx ASP Control:

  function mute() {       
        var button_mute = document.getElementById('<%= btnRequestCompanyCheck.ClientID %>');
        button_mute.style.display = "none";
        alert("x");

    }

How I can call mute() from Code behind (test.ascx.cs), I am trying all of below list, no one is working for me. Which one should I used on Asp Control?

ScriptManager.RegisterOnSubmitStatement(this, this.GetType(), "test", "mute()");
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "test", "mute()", true);
ScriptManager.RegisterStartupScript(this, this.GetType(), "test", "mute()", true);
ScriptManager.RegisterStartupScript(this, this.GetType(), "test", "mute()", true);
Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction","mute()", true);

• 2 mute() is supposed to occur in the browser in response to an event handler on the server? how is the server supposed to send that message to the client? is the event handler running as a full postback or partial postback? We need more info to help. – Tetsujin no Oni Commented Jun 5, 2014 at 13:57

Did you tried this?

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="javascript:return mute();" />

And here is the javascript code.

<script type="text/javascript">
function mute() {
    alert("Muted");

    return false;
}
</script>

Here is the code behind alternative

Page.ClientScript.RegisterStartupScript(this.GetType(), "Script", "mute()", true);

you have to register ScriptManager on parent control like

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>

after you can use,

 Page.ClientScript.RegisterStartupScript(GetType(), "indexonchange", "OnIndexChange();", true);

try this:

ScriptManager.RegisterStartupScript(this, this.GetType(), "test", "javascript:mute();", true);
