This blog explores the advanced custom editing features in the JavaScript Gantt Chart designed to streamline your project management.

Effortless corrections: Enhancing JavaScript Gantt Chart with undo/redo capabilities

The undo/redo feature enhances user control by allowing quick reversals and reinstatements of actions on the Gantt Chart. This feature is crucial for managing complex projects. It aids in swiftly correcting both accidental and intentional entries, boosting overall workflow efficiency.

Immediate error correction

Imagine a project manager reassigning tasks, inadvertently causing task overlaps. With the undo feature ( Ctrl+Z ), we can instantly revert these changes or reapply them with redo ( Ctrl+Y ) after reassessment, ensuring optimal task alignment without permanent errors.

Activating undo/redo functionality

The following code explains how to enable the undo/redo feature in the JavaScript Gantt Chart.

let gantt: Gantt = new Gantt({
    enableUndoRedo: true,
});

We can also include the Undo and Redo buttons in the toolbar, as demonstrated in the following code example.

let gantt: Gantt = new Gantt({
    toolbar: ['Undo', 'Redo'],
});

Refer to the following image.

Precision editing: Customizing dialog fields for error-free Gantt Chart

Integrating custom dialog fields into the JavaScript Gantt Chart gives flexibility to your project management tools. This feature enables you to add both predefined and unique fields to the general tab and extend these customizations to other tabs, offering extensive personalization options throughout the dialog.

Complex project data management

Consider a project manager overseeing a large construction project with multiple overlapping phases and a diverse team. The standard fields in a Gantt Chart might not capture all the necessary details, such as specific material requirements, subcontractor information, or custom milestones that are crucial for this project.

How do custom dialog fields help?

1. Expanding the general tab

By introducing additional fields into the General tab, project managers can enter and access specific project-related data directly within the Gantt Chart. This customization allows for immediate viewing and modification of critical information, enhancing the manageability of complex projects.

Refer to the following code example to add a template field called newInput into the general tab.

let gantt: Gantt = new Gantt({
    addDialogFields: [
        { type: 'General', headerText: 'General add', fields: ["TaskID", "TaskName", "newInput"] },
    ],
    editDialogFields: [
        { type: 'General', headerText: 'General edit', fields: ["TaskID", "TaskName", "newInput"] },
    ],
});

2. Enhancing other tabs with additional functionalities

Beyond just adding fields, you can also add sorting, filtering, and customized column arrangements in tabs like Resources or Dependencies by using the Grid / Treegrid model properties.

Refer to the following code example to enable advanced features in the Dependencies tab.

let gantt: Gantt = new Gantt({
    addDialogFields: [
        { 
            type: 'Dependency', 
            additionalParams: {
                allowPaging: true, 
                allowSorting: true, 
                toolbar: ["Search", "Print"]
            }
        },
        { 
            type: 'Resources', 
            additionalParams: { 
                allowSorting: true, 
                allowPaging: true, 
                toolbar: ["Search", "Print"], 
                columns: [{ field: "newData" }]
            }
        },
        { 
            type: "Segments", 
            additionalParams: {
                columns: [{ field: "segmenttask", width: "170px", headerText: "Segment Task" }]
            }
        },
    ],
    editDialogFields: [
        { 
            type: 'Dependency', 
            additionalParams: {
                allowPaging: true, 
                allowSorting: true, 
                toolbar: ["Search", "Print"]
            }
        },
        { 
            type: 'Resources', 
            additionalParams: { 
                allowSorting: true, 
                allowPaging: true, 
                toolbar: ["Search", "Print"], 
                columns: [{ field: "newdata" }]
            }
        },
        { 
            type: "Segments", 
            additionalParams: {
                columns: [{ field: "segmenttask", width: "170px", headerText: "Segment Task" }]
            }
        },
    ],
});

3. Customizing the Notes tab for rich content management

Tailoring the Notes tab with the Rich Text Editor (RTE) model customizations not only enriches the tab’s functionality but also enhances the content creation and editing experience, perfect for managing detailed project notes and documentation.

let gantt: Gantt = new Gantt({
    addDialogFields: [
        { 
            type: 'Notes', 
            additionalParams: { 
                inlineMode: { 
                    enable: true, 
                    onSelection: true 
                } 
            }
        },
    ],
    editDialogFields: [
        { 
            type: 'Notes', 
            additionalParams: { 
                inlineMode: { 
                    enable: true, 
                    onSelection: true 
                } 
            }
        },
    ],
});

By integrating these features into the JavaScript Gantt Chart, you can unleash a new level of customization and efficiency, elevating the user experience to new heights.

Streamlined reporting: Using templates for professional PDF exports in JavaScript Gantt Chart

Exporting your Gantt Chart to PDF using customizable templates ensures stakeholders receive clear, concise, and visually appealing reports highlighting critical project information and timelines.

Professional stakeholder reporting

Consider a scenario where project managers must regularly update stakeholders on project progress. These stakeholders may range from team members and internal management to external clients and investors. To enhance readability and professionalism, these reports must be accurate and professionally formatted.

How to use custom templates for PDF exports?

Header template: Start by crafting a customized header for your grid part of Gantt that introduces the project and sets the professional tone of the document.
Label templates: Depending on the detail level required, choose right-, left-, or task-specific labels that render around the taskbar in Gantt.
Taskbar template: Use different visual styles for phases or tasks to provide a quick overview of the project timeline.

The pdfQueryTaskbarInfo event facilitates the integration of base64-format images and customized text into PDFs for the templates mentioned above, enhancing your reports’ visual appeal and information density. This customization capability ensures that your Gantt Chart exports meet your audience’s specific needs and preferences.

Note: For more details, refer to the PDF export in JavaScript Gantt Chart documentation.
