Usercontrol和page傳值－趴

UC中拉了一個TEXTBOX,TEXT內設定文字為"這是測試"

以下為UC的原始碼


<%@ Control Language="C#" AutoEventWireup="true" CodeFile="labelcountrol.ascx.cs" Inherits="labecountrol" %>

<asp:TextBoxID="TextBox1" runat="server">這是測試</asp:TextBox>



以下為UC的程式碼 UC檔名取名為 labelcountrol


public partial class labecountrol : System.Web.UI.UserControl
{
      
    public void settxt(string mm)
    { 
        this.TextBox1.Text = mm;
    }
    
    public string gettxt()
    {
        return this.TextBox1.Text;
    }
}



以下為page的程式碼


public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        this.MyHeader1.settxt("ya");
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        this.Label1.Text = this.MyHeader1.gettxt();
        
    }
}
