UI Automation Activities

Last updated Nov 12, 2025

Update UI Element (former Set Value)

UiPath.Semantic.Activities.NSetValue

Description

Uses AI to seamlessly set a value on any input field: input box, drop-down, check box, radio buttons, date picker.

It can be used only on Chrome Edge, Firefox, and Safari.

Uses the same functionality as Fill Form, but on element level.

Instead of using other activities for specific input fields (for instance, Type Into for input boxes, Check/Uncheck for check boxes, etc.), you can use a single generic Update UI Element activity. It can also deal with date pickers and groups of radio buttons.

This activity must be added inside a Use Application/Browser activity.

This activity is compatible with Object Repository.

Project compatibility

Windows | Cross-platform

Configuration

  • Indicate target on screen - Indicate the UI element to use as target.

    After you indicate the target, select the plus button to access the following options:

    • Indicate target on screen - Indicate the target again.
    • Edit target - Open the selection mode to configure the target.
  • Value - The value set on the field. This field accepts only String variables.
    If the indicated target is a checkbox, these are the accepted values:
    • True: "true", "yes", "checked", "x"
    • False: "false", "no", "unchecked"
  • Enable validation - Enables execution validation for the run-time value is the toggle button is set to On. An exception is thrown if the internal validation mechanism detects an invalid value after the execution. The default option is Off.

Options

  • Healing Agent mode - Configures the behavior of the Healing Agent for this activity, based on Governance or Orchestrator settings at process or job level.
    • Disabled - Turns off the Healing Agent for this activity.
    • Inherit job settings - Applies the settings defined in Governance or in Orchestrator at the process or job level.
    • Recommendation only - Enables the Healing Agent to provide recommendations on how to fix UI automation issues on running jobs, but only if permitted by Governance or Orchestrator settings.
    • Same as App/Browser - Inherits the configuration from the parent Use Application/Browser activity.
  • Continue on error - Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to True, the execution of the project continues regardless of any error.

Target

  • Expand target properties - Display target and anchor properties. This will hide the other activity properties and display only those related to the target.
  • Collapse target properties - Hide target and anchor properties. This will hide target related properties and display the activity properties.
  • Targeting methods - The selector types that you want to use for identifying the element. This property can be set to any combination from the drop-down menu:
    • None
    • Strict selector - The strict selector generated for the target UI element.
    • Fuzzy selector - The fuzzy selector parameters.
    • Computer Vision - To use Computer Vision as a targeting method, you need to go to Project Settings > Computer Vision and make sure to set the correct server endpoint. You can leave this field as it is and use UiPath Cloud, which is filled-in by default, or you can enter another value either by selecting any of the other public endpoints specific to a server region or your own on-premises server.

      Another way of using Computer Vision as a targeting method is to set Use Local Server to True. This implies that the UiPath.ComputerVision.LocalServer package is installed in your project. When Local Server is enabled, the server value is over-written. However, the Local Server is not available in cross-platform projects.

      • CV Control type - Indicates the type of control identified using Computer Vision.
      • CV Text - Indicates the text identified using Computer Vision.
      • CV Text occurrence - Indicates a specific occurrence to be used, when multiple matches are found.
      • CV Text accuracy - Indicates the accuracy level for OCR text matching.
    • Semantic selector - Leverages large language models (LLMs) to generate functional, human-like descriptions of UI elements. These descriptions are highly reliable making them adaptable to UI changes and significantly improving automation resilience when traditional selectors fail.
    • Image (Windows only)
      • Image accuracy - Indicates the accuracy level for image matching.
      • Image occurrence - Indicates a specific occurrence to be used, when multiple matches are found.
    • Native text (Windows only)
      • Native text - The text to find to identify the UI element.
      • Native text occurrence - Indicates a specific occurrence to be used, when multiple matches are found.
  • Window selector (Application instance) - Selector for the application window. Only applicable when window attach mode is set to application instance.
  • Wait for page load - Before performing the action, wait for the application to becaome ready to accept input. The options are:
    • None - Does not wait for the target to be ready.
    • Interactive - Waits until only a part of the app is loaded.
    • Complete - Waits for the entire app to be loaded.
  • Visibility check - When enabled, the activity also checks whether the UI element is visible or not. You can choose one of three options from the drop-down menu:
    • None - Does not check for visibility.
    • Interactive (for Fuzzy Selector) - Default option. Checks if the element is potentially visible, ignoring page scroll and obstructions by other apps, or the fact that the application is minimized. This check is useful when trying to ensure that you are not targeting invisible elements that exist in the DOM but are hidden.
    • Fully visible - Checks if the UI element is visible or not.
  • Responsive websites - Enable responsive websites layout.

Timings

  • Delay before - Delay (in seconds) between the time the previous activity is completed and the time this activity begins performing any operations. The default value is 0.2 seconds. Adding a delay between activities ensures that one activity has enough time to complete before the next activity begins.

  • Delay after - Delay (in seconds) between the time this activity is completed and the time the next activity begins any operations. The default value is 0.3 seconds. Adding a delay between activities ensures that one activity has enough time to complete before the next activity begins.

  • Timeout - Specify the amount of time (in seconds) to wait for the activity to be executed before throwing an error. The default value is 30 seconds.
