Set Attribute Activity

The Set Attribute activity modifies the value of a specific attribute on a UI element within a native Windows desktop application.

Field Description Requirement
Application instance The reference name of the application instance previously opened or attached. Required
Element The JSON-based selector identifying the target element. Required
Label An alternative to Element that identifies the target by label instead of a selector. Optional
Label match type Defines how Label is compared against candidate elements (e.g., Equals, Contains). Optional
Attribute name The name of the attribute to modify. Required
Value The new value to assign to the specified attribute. Required

Action Types & Examples

Attribute Assignment

  • Format: string
  • Example Result: "false"

Implementation Examples

Field Setup - Application instance: ${appInstance} - Element: the target control identified by the UI Automation Inspector - Attribute name: Enabled - Value: false

Technical Notes

Label and Label match type provide an alternative to Element for identifying the target, useful when a stable selector is not available. Provide either Element or Label, not both.
