    Send e-mail

    Compose a new message

    This application scenario demonstrates how to implement a simple form for sending a message to a list of recipients.

    • The RadAutoCompleteBox is bound to the list of friends names.
    • Upon writing, a drop down with values containing the use input will be displayed.
    • The first match will be highlighted and selected with the Enter or with the mouse. The up and down arrows can be used to select some of the names in the dropdown.
    • To remove some of the names, the user will need to press backspace twice or click on the delete icon.
    • To send the message user will need to click the "Send Message" button.
