How to Convert View Page consist of tables into PDF file in dot net MVC Core 3.1

Given a view page, you can use the Virtual Printer in the LEADTOOLS SDK to convert a page to a PDF in a .NET Core app. The Virtual Printer can be used to capture a print job, and then used to save the image to the file. This supports a large variety of other file format which you can try. Here is code that you can use to get started.

LeadPrinter = new Printer(printerName);
LeadPrinter.EmfEvent += new EventHandler(LeadPrinter_EmfEvent);
LeadPrinter.JobEvent += new EventHandler(LeadPrinter_JobEvent);
DocumentWriter = new DocumentWriter();
static void LeadPrinter_EmfEvent(object sender, EmfEventArgs e)
{
Metafile metaFile = new Metafile(e.Stream);
DocumentWriterEmfPage documentPage = new DocumentWriterEmfPage
{
EmfHandle = metaFile.GetHenhmetafile()
};
DocumentWriter.AddPage(documentPage);
}
static void LeadPrinter_JobEvent(object sender, JobEventArgs e)
{
string printerName = e.PrinterName;
int jobID = e.JobID;
if (e.JobEventState == EventState.JobStart)
{
OutputFile = Path.Combine(@"C:\Temp", Path.ChangeExtension(Path.GetRandomFileName(), "pdf"));
DocumentWriter.BeginDocument(OutputFile, DocumentFormat.Pdf);
Console.WriteLine($"Job {jobID} for {printerName} was started");
}
else if (e.JobEventState == EventState.JobEnd)
{
DocumentWriter.EndDocument();
Console.WriteLine($"Job {jobID} for {printerName} was ended. PDF saved to {OutputFile}");
}
}

Hi Sachin

Thanks for this

but it having many issues

2.Not Download complete View Page as same style

When you are facing a problem in generating pdf from the server-side then play in the safe zone and try the client-side as shown below.

Layout="yourlayout"
}

"Wrapper">
