Gnostice Document Studio .NET Multi-format ASP.NET Document Viewer is the next-generation multi-format document-viewing technology for .NET developers. The DocumentViewer control supports viewing, form-filling, text searching (with OCR support) and printing PDF, DOCX, DOC, TXT, BMP, JPEG, PNG, WMF, EMF, and single-page and multi-page TIFF. It works on both desktop(Windows 7, Windows 8.1, Windows 10, Linux, Mac OS X) and mobile browsers (IOS, Android, Windows Phone).
Version 2019 R1 - March 14, 2019
- ASP.NET Document Viewer
- Client-side APIs:
- Introduced “lazyLoading” property on “preferences”. Setting lazyLoading to false causes the viewer to continue to load the document in background until all pages of the document are loaded and displayed in the viewer. This setting is useful for form filling scenarios. The “onFormLoaded” event is fired after all form fields on all the pages of the document are loaded and displayed in the viewer.
- Introduced “setTabStop” API on the form field object to enable/disable tab stop for a specified form field.
- Introduced “downloadFileformat” property on “beforeDownloadDocument” event which can be used to set the default download file format.
- German and French localization resource files are added for WinForms Document Viewer.
