Tuesday, December 16, 2025 at 9:00AM Today, Red Software updates RAD PDF, a ASP.NET web component & GUI for editing, form filling, redacting, signing, and viewing PDF files on almost ANY device. RAD PDF supports everything from the latest versions of Chrome and mobile Safari to even Internet Explorer 6! RAD PDF runs on the .NET Framework (3.5 / 4.x) as well as .NET Core, 5, 6, 7, 8. 9, and 10 using Blazor, Razor, MVC, WebForms, and more. Our nuget can be installed on Windows or Linux machines.
This version includes form field calculation improvements, GUI improvements, and more annotation information. Simple PDF form field calculations can now be run server side, allowing for server side changes to be propagated. The object focus outline is now larger, and customizable via CSS. Also, annotation modification dates are viewable in the object properties dialog and as a tooltip in the comments side panel. Additionally, popup annotation connection lines are more intellegent, and now snap to the best corner.
