When using Telerik Document Processing (PdfProcessing) for embedding Factur-X invoices, the produced PDF document is Non‑compliant with PDF-AF / Factur‑X according to the following validator:
https://www.superpdp.tech/outils/validateur-facture-electronique/
RadSpreadProcessing expects an integer, instead of boolean. However, according to the specification, it should be boolean:
After merging several PDF documents, some pages are blank indicating the following error:
The XlsxPartNames class expects a strict name for reading the comments parts:
public const string CommentsPartName = @"/xl/comments{0}.xml";
However, some third-party tools may change the name to GemComments.xml for example.
MS Excel recognizes this naming for the comments part. It would be nice to provide such functionality in RadSpreadProcessing.
XlsFormatProvider: InvalidOperationException is thrown when importing a document with an unsupported BIFF record.
Workaround: Re-save the file with Excel before importing it.
When imported in the WordsProcessing model, the current HTML doesn't respect the defined column width and all columns have identical width:
<colgroup>
<col span="1" style="width: 33.3302%;">
<col span="1" style="width: 17.5658%;">
<col span="1" style="width: 49.104%;">
</colgroup>Observed result:
Expected result:
Workaround: use the width property as follows:
<colgroup>
<col span="1" width="33.3302%">
<col span="1" width="17.5658%">
<col span="1" width="49.104%">
</colgroup>
The current formula:
<c r="A1" s="1">
<f>[1]BILANS_JI!$C$2</f>
<v>22611518.026189998</v>
</c>
• Simple direct reference to a single external cell [1]BILANS_JI!$C$2
• No function, just a linked cell
The expected value to be returned is 22611518.
The issue is reproducible with PDF form fields and setting Polish characters to the text fields: e.g. "ęóąśłżźćń"
Edit mode in RadPdfViewer:
Exit edit mode:
Here is a sample code snippet for reproducing the case without UI:
PdfFormatProvider provider = new PdfFormatProvider();
RadFixedDocument document = provider.Import(File.ReadAllBytes("file.pdf"), TimeSpan.FromSeconds(10));
foreach (RadFixedPage page in document.Pages)
{
foreach (Annotation annotation in page.Annotations)
{
if (annotation.Type == AnnotationType.Widget)
{
Widget widget = (Widget)annotation;
var field = widget.Field as TextBoxField;
if (field != null)
{
field.Value = "ęóąśłżźćń.";
}
}
}
}
string outputFilePath = "result.pdf";
File.Delete(outputFilePath);
File.WriteAllBytes(outputFilePath, provider.Export(document, TimeSpan.FromSeconds(10)));
Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
As a result of the below missing operator, some of the glyphs can't be extracted from the CFFFontTable and the characters are not displayed in the PdfViewer:
The end user result is missing letter from the PDF content.
