Here are the steps:
1. Copy some basic content from Excel (two text cells)
2. Paste the content to the Telerik Blazor Spreadsheet component and save the XLSX file
3. Try importing this file with RadSpreadProcessing
Hi, we are facing the below error when trying to convert a Docx file type to PDF type using RadFlowDocument in C# (.NET core 6.0). Please can you help with this issue as soon as possible?
Error message: "Negative height, if converting in Net Standard try registering a smaller font (Parameter 'height: -17.908799999999985')"
C# code snippet for reference:
BinaryFormatProviderBase<RadFlowDocument> provider;
RadFlowDocument document;
using (var output = new MemoryStream())
{
provider.Export(document, output)
}
trying to open the attached workbook with this code:
Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
using (Stream input = File.OpenRead("sample.xlsx"))
{
var provider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();
// The import method enables you to also pass a byte[] with the XLSX document data
workbook = provider.Import(input, TimeSpan.FromSeconds(30));
}
I get an unhandled exception:
An unhandled exception of type 'System.ArgumentNullException' occurred in Telerik.Documents.Spreadsheet.dll
Value cannot be null.
Any idea what's going on?
Thank you for your time,
Phil
when parsing a specific document.
Hi Telerik,
Could you add abbility to contact TSA (timestamp) server and sign PDF document with certificate (which is currently supported) and signed timestamp?
Thank you
This would allow repeating header rows on every printed page. More information related to this functionality may be found on the following link: https://support.office.com/en-us/article/Print-rows-with-column-headers-on-top-of-every-page-d3550133-f6a1-4c72-ad70-5309a2e8fe8c
Guidelines of how to provide a custom implementation of the JPXDecode filter can be found in the Customize Rendering section of the documentation and a sample implementation can be found in the SDK examples.
Converting some DocX files to PDF format with page numbering leads to incorrect formatting in the exported PDF:
Input DocX:
Output PDF:
The table styles are not imported correctly from HTML. The back color is not respected. The column width is incorrect. The font size is different.
Font is not in proper case- All the cases are in lower case
Hi,
We are using HTMLFormatProvider and PDFFormatProvider for converting HTML string to PDF file. The below issues are identified while converting PDF.
1. Text Foreground and Background color is not working in pdf.
HTML:
<p><span style="color: rgb(216, 55, 98); background-color: rgb(28, 122, 144); font-size: 30px;">Test</span></p>
We get the same issue even though we added below code.
foreach (Run run in document.EnumerateChildrenOfType<Run>()) { if (!run.Properties.HighlightColor.HasLocalValue) { run.HighlightColor = run.Shading.BackgroundColor.LocalValue; } }
Attached the PDF file
2. Strikeout is not working in PDF
Sample HTML:
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<p><span style="font-size: 24px;"><del>Delete Strike Through line in the paragraph</del></span></p>
</body>
</html>
attached the PDF file .
It would be appreciated , if you provide the solution for those issues

Telerik expose beautyfull document processing: you can automate a lot of thinks in document without user interaction.
But doesn't exists nothing about print this documents without user interaction: you have to open document on a webpage in a component and the print it.
For example: filling out a form can be done internally by process but not printed it.

When a document containing a SignatureField is exported with the IsEncrypted property set to true, a not set UserPassword is required to open it, which makes it impossible to be opened.
Workaround: Exporting with AES256 encryption does not have this problem:
provider.ExportSettings = new PdfExportSettings
{
IsEncrypted = true,
EncryptionType = EncryptionType.AES256
};
