asp.net Repeater控件的使用方法

今天学习了，Repeater控件

repeater绑定数据：

 protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
            BindStudent();
    }

    private void BindStudent()
    {
        string str = ConfigurationManager.ConnectionStrings["stucnn"].ConnectionString;
        using (SqlConnection sqlCnn = new SqlConnection(str))
        {
            using (SqlDataAdapter da = new SqlDataAdapter("select * from student", sqlCnn))
            {
                DataSet ds = new DataSet();
                da.Fill(ds);
                this.Repeater1.DataSource = ds;
                this.Repeater1.DataBind();
            }
        }
    }

 

删除数据：

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        if (e.CommandName == "Delete")
        {
            string str = ConfigurationManager.ConnectionStrings["stucnn"].ConnectionString;
            using (SqlConnection sqlCnn = new SqlConnection(str))
            {
                using (SqlCommand sqlCmm = sqlCnn.CreateCommand())
                {
                    sqlCnn.Open();
                    sqlCmm.CommandText = "delete from student where sid="
                        + e.CommandArgument.ToString();
                    sqlCmm.ExecuteNonQuery();
                }
            }
            this.BindStudent();
        }
        else if (e.CommandName == "Edit")
        {
            Server.Transfer("Edit.aspx?sid=" + e.CommandArgument.ToString());
        }
    }

启用，禁用：

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        //string status = e.CommandName;
        if ((e.CommandName == "true")||(e.CommandName == "false"))
        {
