Length property
Use the Length property to specify the maximum length of a component's value.
For the CHAR data type, the property sets the maximum length of the text.
For the DECIMAL data type, the property sets the maximum number of digits allowed in the number. Length should include the number of digits specified in the Decimal Point Position property plus the maximum number of digits that can appear to the left of the decimal point.
When working with the FlexLayout component, the Length property is used with the Units property to specify the length of each region of a FlexLayout component. Length is expressed as a number of characters, or the number of equal portions of the total available length.
