This document covers the following topics:
Natural for Ajax supports a subset of the Natural edit mask concept in order to support output formatting for most of the commonly used fields.
If edit mask support is specified for a field, the field content is
rendered according to the edit mask during output, and
checked for validity against the edit mask during user input.
Due to the nature of data being handled with a Natural for Ajax client, not all of the different Natural edit mask types make sense. Therefore, only a subset of edit mask types is available for Natural for Ajax.
In all controls that support the property
datatype, edit masks can be specified for the data
types listed in the topics below:
For detailed information on edit masks, see the Natural documentation for the appropriate platform.
Edit masks for numeric fields can be specified for the following data types:
N
n.n
P

xs:double
xs:byte
xs:short
xs:decimal
The full set of Natural numeric edit masks can be applied for these data types.
Edit masks for alphanumeric fields can be specified for the following data type:
string n
The full set of Natural alphanumeric edit masks can be applied for this data type.
Edit masks for date and time fields can be specified for the following data types:
date
time
timestamp (can only be displayed)
xs:date
xs:time
xs:dateTime (can only be displayed)
A subset of the Natural edit masks can be applied for these data types.

The following Natural profile parameters are evaluated for the edit mask processing of Natural for Ajax:
DC
EMFM
For detailed information on these profile parameters, see the Natural documentation for the appropriate platform.
An edit mask is added to a specific data type in the following way:
The datatype property of a field is
specified (here the numeric type N4.2) and the
editmask property is filled with the proper (here
numeric) edit mask.
At runtime, fields with edit masks are processed as follows:
When a field has an edit mask and when a value is to be displayed in that field, the value is processed and formatted according to the edit mask and is displayed afterwards.
When a user enters a value into a field which has an edit mask, the value is validated against that edit mask and the real value is extracted from the entered value by stripping the irrelevant portions of the edit mask.
