How to Get the Position of Scrollbar in Window Using UiPath
In the world of Robotic Process Automation (RPA), UiPath stands out as one of the most powerful tools. Whether you’re automating simple tasks or handling complex processes, knowing how to extract certain data points, such as the position of the scrollbar in a window, is essential for accurate automation. In this blog post, we will guide you through the process of how to get the position of scrollbar in window using UiPath and discuss various methods to achieve this goal effectively.
Why Is It Important to Get the Scrollbar Position?
The scrollbar position indicates the point where a window’s content is currently scrolled to. This information can be crucial in situations where:
- You are dealing with dynamic content.
- You need to monitor the position during long-running automation.
- You need to adjust content visibility during screen scraping or web scraping.
Getting the position of the scrollbar can help UiPath bots make decisions based on the visible content or improve the precision of UI automation
Pre-requisites for Getting the Position of Scrollbar in Window
Before you start, make sure you have the following:
- UiPath Studio installed and configured on your machine.
- Basic knowledge of UiPath selectors and UI Automation activities.
- A window with a scrollable element for testing.
Step-by-Step Guide on How to Get the Position of Scrollbar in Window Using UiPath
1. Use Get Attribute Activity
The easiest way to get the position of a scrollbar in UiPath is by using the Get Attribute activity. Here’s how:
- Open UiPath Studio and create a new process.
- Drag and drop a Get Attribute activity into the workflow.
- Set the Target property to the UI element (scrollbar) in the window you want to inspect.
- From the properties pane, select “VerticalScrollbar” or “HorizontalScrollbar” as the attribute to retrieve.
- The Get Attribute activity will return the scrollbar’s current position as a value, typically a number representing how far the window has been scrolled.
2. Use Send Hotkey Activity for Scroll Actions
In some cases, you may need to simulate scroll actions to get the position of the scrollbar. You can achieve this by using the Send Hotkey activity.
- Choose the Send Hotkey activity and set it to press the Page Down or Arrow Down keys to scroll down.
- After each scroll, use Get Attribute again to check the updated position of the scrollbar.
3. Use Custom Code with Invoke Code Activity
For more advanced users who require a specific solution, UiPath allows you to run custom code using the Invoke Code activity. With this, you can execute C# or VB.NET code to directly fetch the scrollbar position.
// Example of getting scrollbar position in C#
var scrollbarPosition = window.FindFirstChild(“nameOfScrollbar”).GetProperty(“Value”).ToString();
Handling Dynamic Content and Scrollbars
When working with dynamic content, the position of the scrollbar can change frequently, which could affect your automation. It’s important to set up reliable selectors and use techniques like retry scopes to handle dynamic content loading.
How to Adjust the Scroll Position in UiPath
In addition to reading the position, you may want to adjust the scrollbar to a specific location. You can use Set Scroll Position or Send Hotkey activities to simulate user behavior (like clicking and dragging the scrollbar).
Troubleshooting Common Issues with Scrollbar Position in UiPath
- Incorrect Selectors: The position of the scrollbar might not be retrieved correctly if the selector used to identify the scrollbar element is not stable or dynamic.
- Dynamic Windows: Some applications use non-standard scrollbars that UiPath might not detect easily. You may need to use image-based activities to identify the scrollbar position.
- Scroll Beyond Bounds: Ensure that the maximum scroll position is handled to avoid errors when the scroll reaches the end.
Tips for Accurate Scrollbar Position Tracking
- Always test with multiple screen resolutions and window sizes to ensure that your automation works across different environments.
- Combine Get Attribute with other activities like Find Element or Element Exists to validate the visibility of content.

FAQ
To get the scrollbar position in UiPath, use the Get Attribute activity with the VerticalScrollbar or HorizontalScrollbar attribute to retrieve the current scroll position.
Yes, you can use a loop with the Get Attribute activity to track the scrollbar position in real-time, adjusting the flow based on changes in the scroll position.
For dynamic content, use reliable selectors and activities like Retry Scope to handle changes in the UI and ensure that your automation accounts for dynamic changes in scrollbar positions.
Yes, you can adjust the scroll position using Send Hotkey to simulate scroll actions or use other UI automation activities to directly move the scrollbar.
If UiPath is unable to detect the scrollbar, use Image-based Activities like Find Image or Click Image to identify the scrollbar manually.
