CSHTML form to PDF File.

So i have some form in my cshtml view that saves all the data correctly inside the corresponding model, and i need to get these input data and display them inside a pdf file. I tried using QuestPDF, DinkToPDF and BouncyCastle methods and none really worked. This is the project : "https://github.com/GentiOsmani/DeklarimiPasurise" So the forms are filled inside this directory : "DeklarimiPasuris>Views>Declare>Create.cshtml". They Are saved at this directory : "DeklarimiPasuris>Models>DeclarationModel". And they are shown at this directory: "DeklarimiPasuris>Views>Declare>Details.cshtml". The pdf should download when this button is clicked : "<td><a class="btn btn-primary" asp-action="DownloadPdf" asp-controller="Declare">Shkarko</a></td>" (line 38), Inside of this directory : "DeklarimiPasuris>Views>Declare>Index.cshtml". If someone could help me it would be a blessing. Best Regards, Genti.

When you ask a question, make sure you include as much detail as possible. Such as code, the issue you are facing, and what you expect the result to be. Upload code here https://paste.mod.gg/ (see $code for more information on how to paste your code)

I assume that QuestPDF wasn't giving you bouncy castle errors for example, and it would be a lot easier to help fix whatever bouncy castle error you're getting if you listed it explicitly

this was it i think

Gramore•10mo ago

Kewl, so do you have either of those dependencies added? presumably this: https://www.nuget.org/packages/itext7.bouncy-castle-adapter/8.0.1

itext7.bouncy-castle-adapter 8.0.1

Bouncy-castle adapter module
