Manage MS Project Group Criteria with Aspose.Tasks

Introduction

Aspose.Tasks for .NET is a powerful API that allows developers to work with Microsoft Project files programmatically. In this tutorial, we’ll explore how to manage the Group Criterion collection within MS Project using Aspose.Tasks.

Prerequisites

Before we begin, ensure you have the following:

1. Aspose.Tasks for .NET: Make sure you have the Aspose.Tasks library installed in your .NET project. You can download it from here.

2. Microsoft Project File: Have a Microsoft Project file (MPP) ready to work with.

Import Namespaces

Firstly, you need to import the necessary namespaces to your C# code. This step is crucial for accessing the functionalities provided by Aspose.Tasks.

using Aspose.Tasks;
using System;
using System.Collections.Generic;

Step 1: Load the Project File

Initialize a Project object by loading the MPP file.

string DataDir = "Your Document Directory";
var project = new Project(DataDir + "ReadGroupDefinitionData.mpp");

Step 2: Access Group Criteria

Retrieve the group from the project and access its criteria.

var group = project.TaskGroups.ToList()[0];

Step 3: Iterate Over Group Criteria

Loop through each criterion in the group and display its properties.

foreach (var criterion in group.GroupCriteria)
{
    Console.WriteLine("Index: " + criterion.Index);
    Console.WriteLine("Field: " + criterion.Field);
    Console.WriteLine("Group On: " + criterion.GroupOn);
    Console.WriteLine();
}

Step 4: Clear Group Criteria

Clear existing group criteria if it’s not read-only.

group.GroupCriteria.Clear();

Step 5: Add New Criterion

Create a new group criterion and add it to the group.

var criterionToAdd = new GroupCriterion
{
    Ascending = true,
    Field = Field.TaskActive
};

if (!group.GroupCriteria.Contains(criterionToAdd))
{
    group.GroupCriteria.Add(criterionToAdd);
}

Step 6: Copy Criteria to Another Group

Copy the criteria from one group to another.

var otherGroup = project.TaskGroups.ToList()[0];

var criteria = new GroupCriterion[group.GroupCriteria.Count];
group.GroupCriteria.CopyTo(criteria, 0);
foreach (var criterion in criteria)
{
    otherGroup.GroupCriteria.Add(criterion);
}

Conclusion

In this tutorial, we’ve learned how to manage the Group Criterion MS Project collection using Aspose.Tasks for .NET. By following these steps, you can effectively manipulate group criteria within your Microsoft Project files programmatically.
