Configuring Load Mask
Canvas promotes user experience in several ways, including visual indicators to represent the progress of the activity within the application.
Progress Indicators (i.e. load masks) are visual indicators of an activity or background process in an application. However, you might want to turn those off completely or want to show those only when the server response is not received within a specific timeframe. Refer Displaying Load Mask based on Server Response and Disabling Load Mask for more information.
If suppose you need a customized load mask, you can do that too with Canvas Technology platform! Refer Custom Load Mask API for more information.
