ASP.NET動態產生控制項
後端網頁代碼.cs protected System.Web.UI.WebControls.Button bt; protected System.Web.UI.WebControls.FileUpload fu; private void Page_Load(object sender, System.EventArgs e) { //根據網址列參數產生上傳檔案物件 if (Request["Type"] != null && Information.IsNumeric(Request["Type"]) && Convert.ToInt32(Request["Type"]) >= 1 && Convert.ToInt32(Request["Type"]) <= 3) { for (int i = 1; i <= Convert.ToInt32(Request["Type"]); i++) { System.Web.UI.WebControls.PlaceHolder objPlaceHolder = (System.Web.UI.WebControls.PlaceHolder)this.FindControl(string.Format("PlaceHolder{0}", i)); fu = new FileUpload(); fu.ID = string.Format("FileUpload{0}", i); objPlaceHolder.Controls.Add(fu); } //產生按鈕及宣告按鈕事件 bt = new Button(); bt.Click += new System.EventHandler(this.Button_Click); PlaceHolder1.Controls.Add(bt);
