Overview

RadChat provides a predefined set of message types. They all have some common functionality which is derived from the MessageBase class. All messages have an Author and CreationDate. The message value is dependent on the given message type so it is not common for all messages.

Adding the Message

Adding a given message is done through the AddMessage method of RadChat. It has the following two overloads.

  • (MessageBase message): pass the already defined type of message.
  • (Author author, string message): pass directly the string message and its Author. The control will internally wrap the string value into a TextMessage.

Sending the Message

When sending a message the SendMessage event will be triggered. Its arguments expose the Message property through which the message that is currently being sent can be customized.

Example 1: Handling the SendMessage event

private void Chat_SendMessage_(object sender, SendMessageEventArgs e) 
    { 
        var author = e.Message.Author; 
        if (author == this.chat.CurrentAuthor) 
        { 
            this.chat.AddMessage(this.currentAuthor, (e.Message as TextMessage).Text); 
            this.chat.AddMessage( this.otherAuthor, this.messageHelper.RecieveMessage(e.Message)); 
 
            e.Handled = true; 
        } 
    } 

Display Position

Depending on the type of the given message, it can have a different value for its MessageDisplayPosition property. This is an enumeration that can have one of the following values.

  • Inline
  • Popup
  • Overlay

For demonstrating the different DisplayPositions, a sample CalendarMessage will be used.

Note, that some message types support modifying their display position, whereas other ones have a fixed value which cannot be controlled.

Cards

RadChat provides mechanism for displaying more complex information in a user-friendly structured manner and allowing the user to interact with it. This is done through the Card Messages. A built-in set of cards is defined to choose from depending on the data that is to be displayed.
