.NET MAUI Chat Events

Updated on Nov 11, 2025

The Telerik UI for .NET MAUI Chat allows you to attach events that will be raised when certain actions occur.

Here is a list of the available events:

• SendMessage—Raised when a message is sent from the chat by the current author (by clicking the send message button or pressing Enter).

• AttachFiles—Raised when the end user picks files to attach.

  • The sender argument, which is of type object, but can be cast to the RadChat type.
  • A ChatAttachFilesEventArgs object which provides the list of files (IList<IFileInfo> FilesToAttach) to attach to the chat message.

• RemoveAttachedFile—Raised when the end user removes an attached file, via the X button of the ChatInputAreaAttachedFileItemView.

  • The sender argument, which is of type object, but can be cast to the RadChat type.
  • • A ChatRemoveAttachedFileEventArgs object which provides the index (Index of type int) of the item that should be removed from the Telerik.Maui.Controls.RadChat.AttachedFilesSource and Telerik.Maui.Controls.RadChat.AttachedFiles.
