There are different types of activities which are used in the web pages or in automating apps and you can easily find them in the section of activities panel categorized under UI automation. These UI activities have many properties in common.

ContinueOnError:  Even when the activity will show error still, the automation will continue its work. This field works in the boolean values. False is the default value in here. The project won’t show any error if the activity on this field is set to true inside the try catch.

Delay After:  It helps in pausing the activity.

Delay Before:  It helps to pause before any activity.

TimeoutMS:  It helps in finding the element before the error is shown.

WaitForReady:  It will wait until the target is ready and before you perform the activity.

Target:  It helps in identifying the element in UI before the activity starts.
