ASP.NET中repeater控件用法實例

本文實例講述了ASP.NET中repeater控件用法。分享給大家供大家參考。具體實現方法如下：

repeater綁定數據：

復制代碼代碼如下:

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();
            }
        }
}

刪除數據：

復制代碼代碼如下:

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());

        }

}

前臺：

復制代碼代碼如下:
