在页面里写用户控件里的按钮的事件

 用户控件里:

  /// <summary>
        /// 公开按钮
        /// </summary>
        public Button SelectFactoryOKButton
        {
            get { return this.btnChooseOneFactoryOK; }
            set { this.btnChooseOneFactoryOK = value; }
        }

用户控件公开了那个按钮，页面里:然后页面取到给自己加一个事件 

 this.UCChooseOneFactory.SelectFactoryOKButton.Click += new EventHandler(SelectFactoryOKButton_Click);

 

 protected void SelectFactoryOKButton_Click(object sender, EventArgs e)
        {
            if (this.UCChooseOneFactory.GetSelectFacotyID().ToString() == "0")
            {
                MessageBox.Show(this.upSelectProductNamePopup, "请选择一个!");
            }
}
