Datalist通過代碼實現數據庫的綁定以及刪除、編輯分頁等效果

沒有使用數據源控件

protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)

    {

        string name = (e.Item.FindControl("TextBox1") as TextBox).Text;

        string sex = (e.Item.FindControl("TextBox2") as TextBox).Text;

        string age = (e.Item.FindControl("TextBox3") as TextBox).Text;

        string str = ConfigurationManager.ConnectionStrings["studentCnn"].ConnectionString;

        using (SqlConnection sqlCnn = new SqlConnection(str))

        {

            SqlCommand sqlcmm = sqlCnn.CreateCommand();

            sqlcmm.CommandText = "update student set sname=@sname,sex=@sex,age=@age where sid=@sid";

            sqlcmm.Parameters.AddWithValue("@sname", name);

            sqlcmm.Parameters.AddWithValue("@sex", sex);

            sqlcmm.Parameters.AddWithValue("@age", age);

            sqlcmm.Parameters.AddWithValue("@sid", e.CommandArgument);

            sqlCnn.Open();

            sqlcmm.ExecuteNonQuery();
