我制作了一个简单的购物车模块系统
当我点击第2页时,没有任何内容只显示我在此处上传的空白页
namespace PaymentGateWay
{
public partial class Payments : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
readcoupons();
// dt = new DataTable();
// DataTable dtn = new DataTable();
// dt.Columns.Add("chkstatus");
// dt = dtn;ViewState["dt"]
ViewState["dt"] = "NULL";
}
}
private void readcoupons()
{
BAL.READDATA readcoupons = new READDATA();
DataSet ds = readcoupons.ReadCoupons();
rg_coupons.DataSource = ds.Tables[0];
rg_coupons.DataBind();
}
答案 0 :(得分:1)
您必须在其NeedDataSource事件中向RadGrid提供数据源,而不是仅在初始页面加载时提供。
服务器代码:
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
BAL.READDATA readcoupons = new READDATA();
DataSet ds = readcoupons.ReadCoupons();
rg_coupons.DataSource = ds.Tables[0];
}
