Customize Gantt Chart Columns with Aspose.Tasks

Introduction

Gantt charts are a fundamental tool in project management, providing a visual representation of tasks, timelines, and resources. Aspose.Tasks for .NET offers powerful capabilities to manipulate Gantt charts, including customizing columns to display specific task information. In this tutorial, we’ll explore how to work with Gantt chart columns using Aspose.Tasks for .NET.

Prerequisites

Before we begin, ensure you have the following:

1. Installation: Aspose.Tasks for .NET installed on your system. If not, download and install it from here.
2. .NET Development Environment: A working knowledge of C# and the .NET framework.
3. Sample Project File: Have a sample Microsoft Project file (.mpp) handy to experiment with. If you don’t have one, you can create a simple project in MS Project and save it.

Import Namespaces

First, you need to import the necessary namespaces to work with Aspose.Tasks for .NET:

    using Aspose.Tasks;
    using System;
    using System.Collections.Generic;
    using System.Globalization;
    
    using Aspose.Tasks.Saving;
    using Aspose.Tasks.Visualization;

Step 1: Load the Project File

Load the project file using the Project class provided by Aspose.Tasks:

// The path to the documents directory.
String DataDir = "Your Document Directory";
var project = new Project(DataDir + "Project2.mpp");
var task = project.RootTask.Children.GetById(1);

Step 2: Define Gantt Chart Columns

Define the columns you want to display in the Gantt chart. You can specify built-in fields or create custom ones:

var columns = new List<ViewColumn>
{
    new GanttChartColumn(20, Field.TaskUniqueID),
    new GanttChartColumn("Name", 150, Field.TaskName),
    new GanttChartColumn("Start", 100, Field.TaskStart),
    new GanttChartColumn("End", 100, Field.TaskFinish),
    new GanttChartColumn("R-Initials", 100, Field.TaskResourceInitials),
    new GanttChartColumn("R-Names", 100, Field.TaskResourceNames),
    new GanttChartColumn("Work", 50, Field.TaskWork),
    new GanttChartColumn(
        "Cost", 
        80,
        delegate(Task t)
        {
            return t.Get(Tsk.Cost).ToString(CultureInfo.InvariantCulture);
        }),
    new GanttChartColumn(
        "Actual Cost", 
        80,
        delegate(Task t)
        {
            return t.Get(Tsk.ActualCost).ToString(CultureInfo.InvariantCulture);
        },
        Field.TaskActualCost)
};

Step 3: Iterate Over Columns

Iterate over the defined columns to access their properties and display information:

foreach (var column in columns)
{
    var col = (GanttChartColumn)column;
    Console.WriteLine("Column Name: " + col.Name);
    Console.WriteLine("Column Field: " + col.Field);
    Console.WriteLine("Column Text: " + col.GetColumnText(task));
    Console.WriteLine();
}

Step 4: Save Gantt Chart to CSV

Save the Gantt chart with defined columns to a CSV file:

var options = new CsvOptions
{
    View = new ProjectView(columns)
};
project.Save(DataDir + "WorkWithGanttChartColumn_out.csv", options);

By following these steps, you can effectively work with Gantt chart columns in Aspose.Tasks for .NET, allowing you to customize and display task information as needed.

Conclusion

Mastering the manipulation of Gantt chart columns in Aspose.Tasks for .NET opens up endless possibilities for tailoring project management visuals to your specific needs. By following the steps outlined in this tutorial, you can efficiently handle task information and enhance project clarity and organization.
