my.ascx:
<% @ Control Language = "c #" AutoEventWireup = "false" Codebehind = "my.ascx.cs" Inherits = "test.my" TargetSchema = "http://schemas.microsoft.com/intellisense/ie5"%>
<asp: TextBox id = "TextBox1" runat = "server"> a4w </ asp: TextBox>

public string Retu1 {
get {
return this.TextBox1.Text;
}
set {
this.TextBox1.Text = value;
}
}

private void Page_Load (object sender, System.EventArgs e)

// Place user code here to initialize the page

}
