1、web页上输入信息，在用户控件上显示信息的方法：
新建一个网页，取名a.aspx
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<uc1:WebUserControl ID="WebUserControl1" runat="server" />
</div>
</form>
</body>
protected void Button1_Click(object sender, EventArgs e)
{
Label Label1 = (Label)WebUserControl1.FindControl("Label1");
Label1.Text = TextBox1.Text;
}
WebUserControl.aspx
2、输入框在页面上，按钮与标签在用户控件里
新建网页PageA.aspx
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
<uc1:UcA id="UcA1" runat="server">
</uc1:UcA></div>
</form>
</body>
protected void Page_Load(object sender, EventArgs e)
{
((Button)UcA1.FindControl("Button1")).Click += new EventHandler(PMS_PageA_Click);
}
void PMS_PageA_Click(object sender, EventArgs e)
{
UcA1.Label1Text = TextBox1.Text;
}
UcA.ascx
protected void Page_Load(object sender, EventArgs e)
{
}
public string Label1Text
{
get { return Label1.Text; }
set { Label1.Text = value.ToString(); }
}
新建一个网页，取名a.aspx
<body> <form id="form1" runat="server"> <div> <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" /> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <uc1:WebUserControl ID="WebUserControl1" runat="server" /> </div> </form></body>a.apsx.cs
protected void Button1_Click(object sender, EventArgs e){
Label Label1 = (Label)WebUserControl1.FindControl("Label1"); Label1.Text = TextBox1.Text; }WebUserControl.aspx
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
把用户控件拖到a.aspx上运行即可<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>2、输入框在页面上，按钮与标签在用户控件里
新建网页PageA.aspx
<body> <form id="form1" runat="server"> <div> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <br /> <uc1:UcA id="UcA1" runat="server"> </uc1:UcA></div> </form></body>PageA.aspx.cs
protected void Page_Load(object sender, EventArgs e){
((Button)UcA1.FindControl("Button1")).Click += new EventHandler(PMS_PageA_Click);
}
void PMS_PageA_Click(object sender, EventArgs e){
UcA1.Label1Text = TextBox1.Text;
}
protected void Page_Load(object sender, EventArgs e){
}
public string Label1Text{
get { return Label1.Text; }
