Hi, Re performance point of view I don't see there's an issue, measure take some time but it not significant.
With a test of a mx datagrid with a 1000 rows and 10 columns of DateFields, displaying full screen and running through advanced telemetry and looking at the results in Scout. On startup DateField.measure takes up less than 1% of the total time (44ms of a total of 5,374ms), scrolling and interacting with the DG it's even less (25ms of 5455ms total). Methods like CreateUID, get name, get compatibilityVersion, getStyle, Date.getMonth or String.isWhitespace take more time than the new DateField.measure. Thanks, Justin
