I'm trying to create an HTML template to export it as a PDF File, but I'm not sure on how to do this using Angular's engine;
What I need to do basically is to build this template when I click a "Download As PDF" button, and this should take all the information I have in one component and use to create an HTML document which will be exported, but not shown on the screen or anything like that.
Since my actual screen and the format I need to have on the PDF file I'm not able to just use the same component's HTML template, so I'm looking to build the template structure I need when I click on the button.
My current component uses mat-tabs to display information, but in the actual PDF I need each tab to be its own individual section in the page; so I would need to build this new HTML structure only when I want to generate the file
Any ideas how i could do something like this?
Based on your criteria this sounds like it needs to be a whole new component that is created specifically to the format needed for the PDF export. You'd add the correct headers such as content-disposition to have your PDF attachment.
Your next task is to determine how to get your data into that new component that is dedicated to PDF export. If you are already using a Redux/NGRX store in your app then that is probably easy enough to use.
A more common way to share data across components within the same module is to utilize an Angular service. This service is injected into both versions of the component and all important data is saved and retrieved from that service.

Background:
I need to allow users to create web pages for various products, with each page having a standard overall appearance. So basically, I will have a template, and based on the input data I need the HTML page to be generated for each product. The input data will be submitted via a web form, following which the data should be merged with the template to produce the output.
I initially considered using a pure templating approach such as Nunjucks, but moved to ReactJS as I have prior experience with the latter.
Problem:
Once I display the output page (by adding the user input to the template file with placeholders), I am getting the desired output page displayed in the browser. But how can I now obtain the HTML code for this specific page?
When I tried to view the source code of the page, I see the contents of 'public/index.html' stating:
This HTML file is a template.
If you open it directly in the browser, you will see an empty page.
Expectedly, the same happens when I try to save (Save As...) the html page via the browser. I understand why the above happens.
But I cannot find a solution to my requirement. Can anyone tell me how I can download/save the static source code for the output page displayed on the browser.
I have read possible solutions such as installing 'React/Redux Development Extension' etc... but these would not work as a solution for external users (who cannot be expected to install these extensions to use my tool). I need a way to do this on production environment.
p.s. Having read the "background" info of my task, do let me know if you can think of any better ways of approaching this.
Edit note:
My app is currently actually just a single page, that accepts user data via a form and displays the output (in a full screen dialog). I don't wish to have these output pages 'published' on the website, and these are simply to be saved/downloaded for internal use. So simply being able to get the "source code" for the dislayed view/page on the browser and saving this to a file would solve my problem. But I am not sure if there is a way to do this?
Its recommended that you use a well-known site generator such as Gatsby or Next for your static sites since "npx create-react-app my-app" is for single page apps.
(ref: https://reactjs.org/docs/create-a-new-react-app.html#recommended-toolchains)
If I'm understanding correctly, you need to generate a new page link for each user. Each of your users will have their own link (http/https) to share with their users.
For example, a scheduling tool will need each user to create their own "booking page", which is a generated link (could be on your domain --> www.yourdomain.com/bookinguser1).
You'll need user profiles to store each user's custom page, a database, and such. If you're not comfortable, I'll use something like an e-commerce tool that will do it for you.
You can turn on the debugger (f12) and go to "Elements"
Then right-click on the HTML tag and press edit as HTML
And then copy everything (ctrl + a)
I am trying to find a way how to import image from html to Crystal Reports. What I found is I need to set a code to download and save the image to a database and then add it to Crystal Report.
In other words, I need to find a way to add image dynamically to the Crystal Reports from HTML using id, rather than save it to a database.
Do you mean save the HTML page as an image and display the result in Crystal? There is a User Function Library (UFL) that provides that functionality. See list of UFLs here.
If you mean an image file referenced by an HTML page, then it's just a file (the fact that it is also used in an HTML page is irrelevant. You can simply use the path to that file.
Consider providing more details...
I am new to angular and looking for a solution where I can select a text file from a list of text files coming from back-end using a checkbox and display its content on click of a button let's say [View Content] in modal window or a dialog box.
The meta-data of all files visible is to be displayed in a table at front-end.
The backend API fetching the file details just provide the id,URL,fileName in json format displayed in a table and files are stored in the file repo lets say google drive.
Any working solution link will be helpful to understand the implementation.
Just make a request and get the file by url using angular http client. And then you can use some library to display it according to the file type.
PS: Image can be fetched directly.
Django shows you forms when you do basic coding, right?
Where is the html of the automatically generated form in windows?
So instead of looking for a template folder, once the developer writes the url or views code, he finds the location of the skeleton-only html that Django shows.
In my opinion, it looks like it's built somewhere like an "anaconda/envs" contains a separate virtual environment, but I can't find it.
it's maybe path?
It's well documented:
https://docs.djangoproject.com/en/2.2/ref/forms/renderers/
It loads templates first from the built-in form templates directory in
django/forms/templates
unless you have 3rd party libraries included that override these templates.
However, a quick check in https://github.com/django/django/tree/master/django/forms/templates/django/forms/ shows that this directory is empty.
tl;dr
Django does not render any forms from scratch (unless it's the Admin which of course creates its whole UI automatically). It just enables you to quickly create a template that can render your form but you will still have to provide a basic template (aka HTML markup with dynamic parts) yourself.
I currently have a "PrintingWebService" that I call from an AJAX page with all the information that is needed to construct a highly customized PDF printout using PDF Sharp and the PDFSharp's GDI+ mode, which takes DrawString and other commands that work basically just like GDI+ only they are drawn to the PDF.
I then save the PDF file to a location on the webserver and return the file name from the web service, and the AJAX page opens a new window with the pdf file.
So far, it works well, however, there is one part of my AJAX page that I want to printout and I haven't come up with a solution for yet. I've got a string of the HTML content of a TinyMCE editor that I want to dispay in the bottom part of the PDF page.
I'm looking for some sort of tool I could use for this purpose. Even something opensource that prints to GDI+ I could use by taking the source code and translating it to use PdfSharp's GDI+ (the class names are like XGraphics, with each class having X before the GDI+ name).
If I have to I will limit what HTML can be generated by TinyMCE and write my own renderer, but that will be a big challenge, so I'm looking for other solutions first.
I've stayed away from a printer-friendly page approach because I wanted to construct a page that was a near identical of an existing WinForms printout, using my existing code. With PdfSharp I was able to convert all the code except the text area stuff (which used the RichTextBox and RTF in the WinForms version).
Tony,
I personally have used WebSupergoo's ABCPdf library with much success. You can actually render HTML directly to the PDF and it does fairly well in regards to accuracy.
Another free software that will allow you the flexibility of writing HTML to PDF that I have used in the past with much success is iTextSharp.
Otherwise, I think you'll have to write something to render HTML to GDI.
Either way, you may want to consider using an HttpHandler that you map to using your web.config to generate the PDF file. This will allow for you to render the PDF to a bytestream and then dump it directly to the user (as opposed to having to save each PDF receipt to the web server). It will also allow for you to use the .pdf extension in the page that returns the receipt (PurchaseReceipt.pdf could be mapped to a HttpHandler)... making it more cross-browser friendly. Older versions of Adobe / Browsers will not display correctly if you start throwing a PDF byte stream from an ASPX page.
Hope this helps.
