Hi, can I save (or convert) formatted (colors, font, tables, etc) content from richTextBox as pdf?

Like as rtf saving:

richTextBox1.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText);

Hi Mate,

Thank you for contacting Syncfusion support.

We have prepared a sample to meet your requirement and in this sample, we have done the following.

     1. Selected all text from RichTextBox as RTF.
     2. Loaded RTF as Stream using Essential DocIO.
     3. Convert loaded Word document into PDF using Essential DocIO and Essential PDF.

Please find the below sample which illustrates the same. Please let us know if it helps you.

If we misunderstood any of your requirement, then kindly provide us your sample or modified above sample and screenshot/output Word document of the expected result along with input which will be helpful to provide you the appropriate solution.

Please let us know if you have any other questions.

Thank you, it works. But proper formatting of rtf seems hard, html much easier. So I think I will use WebBrowser. Can I save content of WebBrowser to pdf?

Hi Mate, 

Yes, we can save the web browser content to PDF using our WebKit HTML converter, but we need to provide the input HTML/URL as input to convert a webpage content to PDF.  

Please refer below links for more information of our WebKit HTML converter, 

You can download latest WebKit installer from below link,  
After installing WebKit HTML converter, you can get the required assemblies, QtBinaries and samples from WebKit installed location.  
Example: $Systemdrive\Program Files (x86)\Syncfusion\WebKitHTMLConverter\xx.x.x.xx\

Hi, it works with my sample project but does not work with my real project.

Assembly versions are identical in sample and real project: 15.1460.0.33

As a trial I copied QtBinaries folder from sample to real project but I get this error message:

This application failed to start because it could not find or load the Qt platform plugin "windows".

Reinstalling the application may fix this problem.

What could be the problem?

Hi Mate, 
1. This error may occurs due to the version mismatch of assemblies and QtBinaries used for HTML to PDF conversion. We usually do changes in assemblies and QtBinaries for every release. So, please make sure you are using the assemblies and QtBinaries from the same WebKit Installer. You can get assemblies and QtBinaries for a specific version by installing the WebKit HTML converter. 
2. This error may occurs if any of the Qt assemblies or subfolder is missing in the QtBinaries folder. So, please make sure all the Qt assemblies are present in the QtBinaries folder, please check the list assemblies with QtBinaries folder from WebKit HTML converter installed location. 
You can get latest WebKit installer from below link,   
You can get specific version of WebKit installer from below link,   
After installing WebKit HTML converter you can get QtBinaries from the WebKit installed location.    
Example: $System Drive:\Program Files (x86)\Syncfusion\WebKitHTMLConverter\XX.X.X.XX    
If still get the same error, please provide the product version, VS version, code snippet and environment details (OS, bit version, culture setting etc.). So, that it will helpful for us to proceed further.

Hi,I checked the versions (VS Path): C:\Program Files (x86)\Syncfusion\Essential Studio\\Assemblies\4.6\Syncfusion.Compression.Base.dllC:\Program Files (x86)\Syncfusion\Essential Studio\\Assemblies\4.6\Syncfusion.HtmlConverter.Base.dllC:\Program Files (x86)\Syncfusion\Essential Studio\\Assemblies\4.6\Syncfusion.Pdf.Base.dllI copied the full QtBinaries folder from here: c:\Program Files (x86)\Syncfusion\WebKitHTMLConverter\\QtBinaries\So I think it should not be a version problem.And in a separated, small project it is working (with same assemblies + webkit).

The problem is the hungarian accented letters in the path of program folder. Can I solve this? It is a multilingual software so various letters can be in the program path.
