我是ASP Net的新手，在这个问题上我有些困惑。 我正在使用嵌套的Gridview，“父网格”汇总了发票的总金额，其中有一个名为“收集金额”的列，“子网格”显示了各个发票的详细信息，还有一个名为“发票金额”的列。收款金额是发票金额的总和。
在子网格中，我有一个复选框，如果用户选中了各个发票行，则需要更新父网格中的收款额。
我一直在网上寻找解决方案，但找不到解决方案。
父项和ChildGrid设置

这将获取所有未付的发票，创建摘要并绑定到父网格。
UnpaidInvoicesList = NotaDebitoManagement.SelectAllNotPaidNotaDebitoInvoices(Page.CountryId, option,
Convert.ToDateTime(NotaDebitoInvoiceDates.SelectedValue),
Convert.ToDateTime(NotaDebitoInvoiceDatesTo.SelectedValue));
List<NotaDebitoManagement.InvoiceGrouping> InvoiceGroup = UnpaidInvoicesList
.GroupBy(ho => ho.HeadOffice)
.Select(ig => new NotaDebitoManagement.InvoiceGrouping
{
HoId = ig.First().HoId,
HeadOfficeName = ig.First().HeadOffice,
TotalAmount = ig.Sum(c => c.PpInclVat),
InvoiceCount = ig.Count(),
}).ToList();
NotaDebitoInvoicesGrid.DataSource = InvoiceGroup;
NotaDebitoInvoicesGrid.DataBind();
对于每个零售商，将未支付的发票添加到子网格中
protected void NotaDebitoInvoicesGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int HeadOfficeID = (int)NotaDebitoInvoicesGrid.DataKeys[e.Row.RowIndex].Values["HoId"];
var gvDebitsGredits = (GridView)e.Row.FindControl("gvDebitsGredits");
var DebitCredits = UnpaidInvoicesList
.Where(o => o.HoId == HeadOfficeID)
.OrderByDescending(ob =>ob.PpInclVat);
if (DebitCredits.Count() > 0)
{
gvDebitsGredits.DataSource = DebitCredits;
gvDebitsGredits.DataBind();
}
}
}
先谢谢了。 达伦
