Can you guys suggest me how could i do this?

There is my Javascript code

<script language="javascript" type="text/javascript">
                        function networkInfo() {

                            var wmi = new ActiveXObject("WbemScripting.SWbemLocator");
                            var service = wmi.ConnectServer(".");

                            e = new Enumerator(service.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True"));

                            for (; !e.atEnd(); e.moveNext()) {
                                var s = e.item();
                                var macAddress = unescape(s.MACAddress);

                            document.getElementById("macaddress").value = macAddress;

and there is my Ascx.cs code

protected void btnLogin_Click(object sender, EventArgs e)
        //Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMacFunction", "networkInfo()", true);
        ScriptManager.RegisterClientScriptBlock(this.Page, typeof(Panel), "CallMacFunction", "networkInfo()", true);
        string MacAddress = macaddress.Value;

This code working fine in aspx page but not working in ascx page.
So please suggest me some solution.

There are many ways to do this. You can just include javascript anywhere and setup an event for that click.

If the javascript is a part of that user control only, and you only want it to be included with the user control, you can put it in a web resource and access it from there.[^]
