Set Vertical Scroll Position in JavaScript Gantt Chart Control

The setScrollTop method in the JavaScript Gantt Chart control enables programmatic control of the vertical scroll position, allowing efficient navigation to specific tasks in large project datasets. By specifying a numeric pixel value (e.g., 100 for 100px), you can scroll the grid portion of the Gantt (task rows) to focus on a desired task or area. For example, clicking a button to scroll to a task at row 50 enhances user experience in projects with thousands of tasks. Ensure the Gantt has a defined dataSource and height (e.g., “600px”) to calculate the scrollable content area accurately. Use pixel-based scroll values to position the viewport precisely, with the maximum scroll limited by the total content height, which varies with dataset size or when enableVirtualization is enabled for optimized performance. This method integrates seamlessly with virtual scrolling and row selection (via selectedRowIndex), making it ideal for automating navigation, such as scrolling to a newly added task or a selected task, enhancing project management workflows.
