We currently have the ability to export a data table here:
https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/formats-and-conversion/data-table/using-data-table-format-provider
Is there a way to export a data set?
 

Dear Telerik Team,

We encounter an issue with export html data to pdf file using below code. For example,

using Telerik.Web.UI;

using OpenXmlSpreadsheet = DocumentFormat.OpenXml.Spreadsheet;
using Pdf = Telerik.Windows.Documents.Flow.FormatProviders.Pdf;
using te = Telerik.Windows.Documents.Flow.FormatProviders.Html;
using tm = Telerik.Windows.Documents.Flow.Model;
using tp = Telerik.Windows.Documents.Primitives;
using tt = Telerik.Windows.Documents.Spreadsheet.Theming;te.HtmlFormatProvider provider = new te.HtmlFormatProvider();

tm.RadFlowDocument document = provider.Import(HttpUtility.HtmlDecode(htmldata));
tt.ThemeFontScheme fs = new tt.ThemeFontScheme("Arial", "Helvetica", "sans-serif");
tt.DocumentTheme theme = new tt.DocumentTheme("PDF", document.Theme.ColorScheme, fs);
document.Theme = theme;
document.Sections[0].PageMargins = new tp.Padding(50, 25, 50, 25);
Pdf.PdfFormatProvider providerPdf = new Pdf.PdfFormatProvider();
byte[] fileBytes = providerPdf.Export(document);

"providerPdf.Export(document);" this line throws exception "An exception occurred during a WebClient request" whenever we include <img src="/image path/image.png" /> html tag.

Your support is appreciated.

I am trying to use Telerik document processing to append some text to an existing pdf document. The text is in Arabic language, that is,  it is Unicode and it has  right to left direction. The resulted pdf document does not show the text even though I can it render the text if I changed the text to  English.

Does Telerik pdf document processing library support Arabic text?

Hi,

I'm using IWorksheetExporter (Telerik.Documents.SpreadsheetStreaming library)  to create big Excel files, ~400 mb xlsx.

I need to add notes to header cells like what is available here https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/notes but it doesn't look to be available in the Streaming library.

I see two possible workarounds.

1. Create my header row with RadSpreadProcessing and reopen the same file for the batch processing with the streaming dll. But I can't find how to append to a worksheet, the only thing that looks like appendable to an existing file is new worksheet.
2. Create the big file with the streaming library and reopen it with RadSpreadProcessing to add the notes. What will be the performance hit to do that? Does opening an excel file load everything in memory? So saving it back will also recreate the whole file?
3. Do you have another solution

NB. Trying to completely create this file via the RadSpreadProcessing library throw a "Stream was too long" from within the library while saving it.

NB. I'm using the latest version from the nuget stream.

Thanks

I have installed the necessary nuget packages for pdf processing in an exisiting Asp.Net Core (.Net 7.0) Blazor project.

Hi,

Is there a way using the Telerik SpreadProcessing library to manipulate the external references in an Excel file?

eg change the source to another file?

thx in advance!

How can I format a set of ranges in a worksheet as a table using document processing?

I couldn't find any source to this matter.

I have attached a screenshot of the Excel function is needed to the desired result.
