Question

Answer 1

Try this

Add this on your cs file to display a confirm instead of alert

string confirm = 
"if(confirm('Are you surely want to do this ??')) __doPostBack('', 'confirmed');";
ScriptManager.RegisterStartupScript(this, this.GetType(), "temp", confirm, true);

Add this on same page to check when user is coming from that confirmation box

protected void Page_Load(object sender, EventArgs e)
{
    string parameter = Request["__EVENTARGUMENT"];
    if (string.Equals("confirmed", 
                        parameter, 
                        StringComparison.InvariantCultureIgnoreCase))
    {
        // Call your server side method here
    }
}

For this I used __doPostBack you can learn more about it from here. Hope it'll help you
