如何動態建立validation,去驗證userControl
今天在論壇上看到這個問題..說難不難..說簡單也還好..就是江湖一點絕..
.. 寫個簡單的範例..看看ㄅ..
UserControl原始碼
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs"
Inherits="usercontrol_WebUserControl" %> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
.aspx原始碼
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="testUsercontrol.aspx.cs"
Inherits="test_testUsercontrol" %> <%@ Register Src="../usercontrol/WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <div> <uc1:WebUserControl ID="WebUserControl1" runat="server" /> </div> </form> </body> </html>
.cs原始碼
public partial class test_testUsercontrol : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //先找到usercontrol's textbox usercontrol_WebUserControl uc = Page.FindControl("WebUserControl1") as usercontrol_WebUserControl; TextBox tb = uc.FindControl("TextBox1") as TextBox; //新增validation RangeValidator rv = new RangeValidator(); rv.Display = ValidatorDisplay.Dynamic; rv.Text = "error"; rv.MaximumValue = "50"; rv.MinimumValue = "0"; rv.Type = ValidationDataType.Integer; rv.ControlToValidate = tb.UniqueID; //加入頁面 form1.Controls.Add(rv); } }
我的作法是一步一步的..先去抓usercontrol..再去抓textbox..
其實也可以WebUserControl1.FindControl("TextBox1") as TextBox直接就這樣去抓..
反正目的就是把"父親兒子的關西"抓出來就好了..^^..
解決收工..
