I'd like to know if it's possible to add Auto-Complete functionality to the Chat UI in WinForms.  I want to be able to tag a user in the chat message.  When I type the '@' symbol I want the auto-complete to start with a prepopulated list of users.

Workaround:

        private void radChat1_ItemFormatting(object sender, ChatItemElementEventArgs e)
        {
            ChatTimeSeparatorItemElement separatorElement = e.ItemElement as ChatTimeSeparatorItemElement;
            if (separatorElement != null)
            {
                if (separatorElement.Text == "TODAY")
                {
                    separatorElement.Text = "TODAY_EN";
                }
                else if (separatorElement.Text == "YESTERDAY")
                {
                    separatorElement.Text = "YESTERDAY_EN";
                }
            }
        }

Please refer to the attached screenshot for a better illustration.

Currently, when you paste a text inside the input box of RadChat, the text is inserted in the text box as preview and you can either commit the message by pressing Enter or delete the text completely. However, if you have an image object in the clipboard and paste it to the input box, a ChatMediaMessage is directly inserted in RadChat without any preview. 

This is a feature request for illustrating a preview image above the input box like most popular chat applications like Skype.

It would be very convenient to scroll to a specific message when a lot of messages are available.
