无需答案。为了测试事情是如何工作的,我从LINQ查询中删除了private void LoadVouchers(int page)
{
var ViewModel = new List<ListVouchersViewModel>();
var PageSize = gvVouchers.PageSize; // Value = 10.
var Skip = page * PageSize; // Value = 1 * 10 = 10 so skip 10 rows.
int SupplierId = int.TryParse(hdSupplierId.Value, out SupplierId) ? SupplierId : 0;
using (ApplicationDbContext Context = new ApplicationDbContext())
{
var Vouchers = Context.Vouchers.Where(x => x.SupplierId == SupplierId && !x.Deleted)
.OrderBy(x => x.DateIssued)
.Skip(Skip);
foreach (var Voucher in Vouchers)
{
// Add a new ListVoucherViewModel to the list.
}
}
gvVouchers.DataSource = ViewModel;
gvVouchers.DataBind();
}
,并且它的页面完全符合我的预期。
我的数据分页有点混乱。当我点击第2页时,重新绑定数据源会完全删除第一页数据。
因此,最初返回14行,页面大小为10行,我可以单击第2页,我正确地看到剩余的4行,但现在我无法再页面,因为前面的10行已从数据中删除源。
这是我的代码:
customcharts.js
如何保留整个数据源,但只显示与所选页面对应的数据源?

private void LoadVouchers(int page)
{
var ViewModel = new List<ListVouchersViewModel>();
var PageSize = gvVouchers.PageSize; // Value = 10.
var Skip = page * PageSize; // Value = 1 * 10 = 10 so skip 10 rows.
int SupplierId = int.TryParse(hdSupplierId.Value, out SupplierId) ? SupplierId : 0;
int totalRowCount = 0;
using (ApplicationDbContext Context = new ApplicationDbContext())
{
totalRowCount = Context.Vouchers.Count();
var Vouchers = Context.Vouchers.Where(x => x.SupplierId == SupplierId && !x.Deleted)
.OrderBy(x => x.DateIssued)
.Skip(Skip);
foreach (var Voucher in Vouchers)
{
// Add a new ListVoucherViewModel to the list.
}
}
gvVouchers.DataSource = ViewModel;
gvVouchers.VirtualItemCount = totalRowCount;
gvVouchers.PageIndex = page;
gvVouchers.DataBind();
}
