c# - 来自 asp.net 3.5 代码隐藏的警告框

Question

protected void ddlLanguage_SelectedIndexChanged(object sender, EventArgs e)
{           
    if (ddlLanguage.SelectedValue=="es-ES")
    {
        Page page = HttpContext.Current.CurrentHandler as Page;

        page.ClientScript.RegisterStartupScript(typeof(Page), "Script", "<script language='javascript'>alert('All content may not be in Spanish. Do you want to continue...');</script>");            
    }
}

我想做的只是显示一个简单的警告框，但一切都是徒劳的……什么都没有弹出。需要一些 ayudar。

也可以通过这种方式实现

protected void ddlLanguage_SelectedIndexChanged(object sender, EventArgs e)
{           
  if (ddlLanguage.SelectedValue=="es-ES")
   {         
      Response.Write("<script>alert('All content may not be in Spanish. Do you want to continue...');</script>");            
   }
}
