This example demonstrates the
insertOnly property which will keep the form in insert mode and is therefore useful for data-entry applications where maximum efficiency is required.
The example also demonstrates the
unique property which is used to ensure the entered contact name is unique. Setting the column
unique property also makes the column required. The message presented to the user when a duplicate name is entered can be customised using the
onUniqueConstraintViolated event to assign a custom message. The sample also demonstrates use of the
placeHolder property that can be used to display some "place holder" text for empty fields as a prompt for user input.
