public void MessageBox(string msg)
        {
            Page page = HttpContext.Current.Handler as Page;
            ScriptManager.RegisterStartupScript(page, page.GetType(), "err_msg", "alert('" + msg + "');", true);

Hey Alert popup is registered to based on condition.

If you want to registered on Page load use this.

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "msg", "alert('your message')", true);

If want to be registered any specific block use this.

ClientScript.RegisterClientScriptBlock(this.GetType(),"alert","Your Message",true);
