Today, we are glad to announce the release of GroupDocs.Viewer for .NET 18.8. In this version, we have introduced the feature of rendering a part of MS Project document specifying the start date and end date. We have also made it possible to set ForcePasswordValidation property of the ViewerConfig using the configuration files such as app.config and web.config. Furthermore, the latest version also includes 14 improvements and bug fixes. Below is the list of new features, improvements, and fixes added in v18.8.

Features Introduced

Rendering a Part of MS Project DocumentYou can now render a part of MS Project document according to specified StartDate and EndDate properties of ProjectOptions class as shown in the below code snippet. When only one of these properties is set, rendering starts from the project’s start date or ends on the project’s end date correspondingly.```

// Setup GroupDocs.Viewer config ViewerConfig config = new ViewerConfig(); config.StoragePath = @“C:\storage”;

// Create image handler ViewerImageHandler imageHandler = new ViewerImageHandler(config); string guid = “document.mpp”;

// Set Project options to render tasks from year 2018 only ImageOptions options = new ImageOptions(); options.ProjectOptions.StartDate = new DateTime(2018, 01, 01); options.ProjectOptions.EndDate = new DateTime(2018, 12, 31);

// Get pages List pages = imageHandler.GetPages(guid, options);

foreach (PageImage page in pages) { Console.WriteLine(“Page number: {0}”, page.PageNumber); Stream imageContent = page.Stream; }
