Master Extended Attribute Definitions MS Project in Aspose.Tasks

Introduction

In this tutorial, we will explore how to work with extended attribute definitions in Microsoft Project using Aspose.Tasks for .NET. Extended attributes offer a flexible way to customize and enhance project data, allowing users to add additional fields beyond the standard ones provided by default. With Aspose.Tasks, you can effortlessly manage these extended attributes to tailor your project management needs.

Prerequisites

Before proceeding, ensure you have the following prerequisites installed:

• .NET Framework
• Aspose.Tasks for .NET library. You can download it from here.

Import Namespaces

First, you need to import the necessary namespaces to access Aspose.Tasks classes and methods in your .NET project. Follow these steps:

Step 1: Open your .NET project

Open your .NET project in your preferred IDE, such as Visual Studio.

Step 2: Add Aspose.Tasks namespace

Add the following line at the beginning of your code file to import the Aspose.Tasks namespace:

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

Now, let’s break down the provided code examples into multiple steps for a comprehensive understanding:

Step 1: Load the project file

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

Step 2: Clear existing extended attribute definitions (optional)

if (!project.ExtendedAttributes.IsReadOnly)
{
    if (project.ExtendedAttributes.Count > 0)
    {
        project.ExtendedAttributes.Clear();
    }
}

Step 3: Create and add extended attribute definition for a task

var taskDefinition = ExtendedAttributeDefinition.CreateTaskDefinition(CustomFieldType.Start, ExtendedAttributeTask.Start7, "Start 7");
project.ExtendedAttributes.Add(taskDefinition);

Step 4: Iterate over task extended attributes

Console.WriteLine("Iterate over extended attributes of " + project.ExtendedAttributes.ParentProject.Get(Prj.Name) + " project: ");
foreach (var attribute in project.ExtendedAttributes)
{
    Console.WriteLine("Attribute Alias: " + attribute.Alias);
    Console.WriteLine("Attribute CfType: " + attribute.CfType);
    Console.WriteLine();
}

Step 5: Create and add extended attribute definition for a resource

var resourceDefinition = ExtendedAttributeDefinition.CreateResourceDefinition(CustomFieldType.Cost, ExtendedAttributeResource.Cost5, "My cost");
if (!project.ExtendedAttributes.Contains(resourceDefinition))
{
    project.ExtendedAttributes.Add(resourceDefinition);
}

Step 6: Insert a resource extended attribute definition

var resourceDefinition2 = ExtendedAttributeDefinition.CreateResourceDefinition(CustomFieldType.Number, ExtendedAttributeResource.Cost1, "My Cost 2");
if (project.ExtendedAttributes.IndexOf(resourceDefinition2) < 0)
{
    project.ExtendedAttributes.Insert(0, resourceDefinition2);
}

Step 7: Remove an extended attribute by index

project.ExtendedAttributes.RemoveAt(0);

Conclusion

In this tutorial, we’ve covered the basics of working with extended attribute definitions in Microsoft Project using Aspose.Tasks for .NET. By following these steps, you can efficiently manage and customize extended attributes to suit your project management requirements.
