        if (!IsPostBack)
        {
            System.Data.DataTable dt = new System.Data.DataTable();

            Repeater1.DataSource = dt;
            Repeater1.DataBind();
        }

    //Repeater的ItemCommand事件
    protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)

        if (e.CommandName == "get")
        {
            Button btn = e.Item.FindControl("Button1") as Button;
            if (btn != null)
            {
                Response.Write("Rpeater控件中的子空间Button的name属性值为:" + btn.UniqueID + "<br/>");
                Response.Write("得到PostBack提交的值:" + Request.Form[btn.UniqueID]);
