Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.MarkedContents.StructAttributeObject'.
PDF content:
Exported text content:
When you register a font in an ASP.Core project and in a static constructor, the generated PDF document will have this font only the first time you load the web page. Refreshing the page will generate the PDF document but the fonts will be lost.
Note: This worked in the previous version 2025.2.701.
When importing a document with an invalid creation or modification date, an exception is thrown:
In Excel formulas, the double minus (--) is known as the "double unary operator." Its main purpose is to convert Boolean values (TRUE/FALSE) into numeric values (1/0).
How it works:
• TRUE becomes 1
• FALSE becomes 0
Example: Suppose you have an array formula like:
=SUM(--(B2:B20="Gamma"))
• (B2:B20="Gamma") produces an array of TRUE/FALSE.
• --(B2:B20="Gamma") converts that array to 1/0.
• SUM(...) then adds up the number of matches.
Some Excel functions (like SUM, SUMPRODUCT) require numbers, not Booleans.
The double unary is a concise way to force this conversion.
SEARCH function with the following format is valid only in Excel 365/2021 or later (with dynamic array support).
"=SEARCH({"Alpha","Beta","Gamma","Delta","Omega","Sigma","Zeta"}, "Omega")"
• It returns an array of numbers or errors, showing the position of each substring in "Omega".
• If a substring is found, you get its position (e.g., 1 for "Omega"); if not, you get #VALUE!.
Paragraphs with a bulleted "Normal" style, but with bullets removed inline, revert to showing bullets after import/export with Telerik Document Processing (DPL)—is not the intended behavior. Inline overrides, such as manually removing bullets from specific paragraphs, should be preserved after processing:
Cached formula values are not respected for the AdditionExpression type.
GetResultValueAsString returns "#NAME?".
