如何将 ASP.NET MVC 上的搜索结果打印成 pdf 格式?
How to print into a pdf the results of a search on ASP.NET MVC?
我是 ASP.NET MVC 的新手,我正在尝试将两个日期之间的过滤记录打印为 PDF。我正在使用 ROTATIVA 生成 PDF,问题是 PDF 生成正确但包含所有记录,而不仅仅是两个日期的记录过滤器的结果。
控制器代码:
//this method is for put the list of the records on the view
public ActionResult SaleList()
{
using (inventoryEntitiesDBA dc = new inventoryEntitiesDBA())
{
return View(dc.sales.ToList());
}
}
//this method is to filter the records between start and end date
[HttpPost]
public ActionResult SaleList(DateTime start, DateTime end)
{
bool Status = false;
if(ModelStatus.IsValid())
{
using(inventoryEntitiesDBA dc = new inventoryEntitiesDBA())
{
var d = dc.sales.Where(x => x.sale_day >= start && x.sale_day <= end).ToList();
Status = true;
ViewBag.Status = Status;
return View(d);
}
}
}
//this method is to generate the PDF
public ActionResult SalesToPdf()
{
var report = new ActionAsPdf("SaleList");
return report;
}
我不知道该怎么做,欢迎任何建议。
*更新 ---> view
:
@if (ViewBag.Status != null && Convert.ToBoolean(ViewBag.Status))
{
//this is for print if the method for filter
//the dates are called
<p align="right">
@Html.ActionLink("Generate PDF", "SalesToPdf2")
</p>
}
else
{
//this is for print if the method for filter the dates are not called
<p align="right">
@Html.ActionLink("Generate PDF", "SalesToPdf")
</p>
}
<center>
@using (Html.BeginForm("SaleList", "Sales", FormMethod.Post))
{
<span>Start Date </span> <input type="date" name="start" />
<span> End Date </span><input type="date" name="end" />
<input type="submit" value="Filter" />
}
</center>
您正在调用不带参数的 SalesToPdf
操作,这意味着它将始终匹配未过滤的列表。您可以将参数传递到 ActionAsPdf
重载中,如文档 here
中所示
在您的情况下,这可能需要对过滤后的列表执行某种单独的操作,如下所示:
[HttpPost]
public ActionResult SalesToPdf(DateTime startDate, DateTime endDate)
{
var report = new ActionAsPdf("SaleList", new {start=startDate, end=endDate});
return report;
}
因此,如果您有未过滤的数据,您将调用现有操作,对于过滤后的数据,您将调用此操作。
