ASP.NET 使用alert弹出对话框后，CSS样式失效，字体变大的解决方法

protected void ASPxButton2_Click(object sender, EventArgs e)
{
//Response.Write("<script>alert('删除成功!')</script>");

WebMessageBox(this.Page, "*******");

}

public static void WebMessageBox(System.Web.UI.Page page, string values)
{
page.ClientScript.RegisterStartupScript(page.GetType(), "", "<script language=javascript>alert('" + values + "')</script>");
}

public static void WebMessageBox(System.Web.UI.Page page, string msg, string href)
{
page.ClientScript.RegisterStartupScript(page.GetType(), "", "<script language='javascript'>alert('" + msg + "');window.location.href='" + href + "';</script>");
}
