Silk Test Workbench lets you use property values of any control in a test application as data in a visual test. To do this, you set the property variable to a local variable that has been defined in the visual test. For example, you can set the ID of a control to a variable, then use the variable in test logic to ensure no other control in the application uses the same ID.
The properties that can be set to a variable depend on the properties available for a control. Not all controls have the same set of available properties.
To set a control property value to a variable, the variable must be created for the visual test.
