Hello,
I'm a noob :)
Goal: Add Header and Footer to generated pages.
IAction in controller responsible for the generation:
[HttpPost]
public async Task<IActionResult> BuildAndDownloadChecklistExport([FromBody] ChecklistExportInput data)
{
try
{
var idUser = userMgr.GetUserId(User)!;
var baseUrl = $"{HttpContext.Request.Scheme}://{HttpContext.Request.Host}";
var html = await viewRenderService.RenderToStringAsync(idUser, "Checklist/_TemplateChecklist", data);
var pdfDoc = new HtmlToPdfDocument()
{
GlobalSettings =
{
PaperSize = PaperKind.A4,
Orientation = DinkToPdf.Orientation.Portrait,
},
Objects =
{
new ObjectSettings()
{
HtmlContent = html,
HeaderSettings =
{
HtmUrl = $"{baseUrl}/Templates/Resources/Checklist_Header.html",
Line = true,
Spacing = 5
},
FooterSettings =
{
HtmUrl = $"{baseUrl}/Templates/Resources/Checklist_Footer.html",
Line = true,
Spacing = 5
}
},
}
};
var pdf = converter.Convert(pdfDoc);
return File(pdf, "application/pdf", "Report.pdf");
}
catch (Exception ex)
{
Debug.WriteLine("Exception in BuildAndDownloadChecklistExport: ", ex.Message);
byte[] pdf = { };
return File(pdf, "application/pdf", "Report.pdf");
}
}Header and footer HTML (Not that it matter, since I tried super minimal html too):
<!DOCTYPE html>
<html>
<head>
<style>
/* Formato A4 */
body {
width: 210mm;
min-height: 297mm;
margin: 0;
padding: 20mm;
font-family: Arial, sans-serif;
box-sizing: border-box;
background: #FFF;
color: #000;
}
.forcedFit {
width: 100%;
}
</style>
</head>
<body>
<div class="ExportHeader">
<img src="/Templates/Resources/Checklist_Header.png" class="forcedFit"/>
</div>
</body>
</html>
If I comment these 2 out:
HeaderSettings =
{
HtmUrl = $"{baseUrl}/Templates/Resources/Checklist_Header.html",
Line = true,
Spacing = 5
},
FooterSettings =
{
HtmUrl = $"{baseUrl}/Templates/Resources/Checklist_Footer.html",
Line = true,
Spacing = 5Everything works, I get the PDF formatted as wanted, but when I try to fit these 2, what returns is a 0byte, unopenable .pdf (No exceptions thrown anywere)
Am I doing something wrong? How should I debug this?
Thank you!
