Group Criterion Data

This article describes how to read and write GroupCriterion data in Microsoft Project files using Aspose.Tasks for .NET. GroupCriterion defines how data is grouped in views, including field name, sort order, and formatting options. The table lists supported properties and shows compatibility across MPP versions. This information is useful for customizing grouping behavior when working with .MPP files programmatically. Developers can use these properties to mirror or modify group definitions found in the Microsoft Project UI.
