I've created a chat, and are now about to set the last touch on the UI and what not. I'm trying to achieve a behavior that enables name on all of the messages (including the latest)
I've attached a image for better understaind.
Thanks in advance.

You can use the ItemFormatting event to show the name label:
private void RadChat1_ItemFormatting(object sender, ChatItemElementEventArgs e){ var messageElement = e.ItemElement as TextMessageItemElement; if (messageElement != null) { messageElement.NameLabelElement.Visibility = ElementVisibility.Visible; }}I hope this helps. Should you have any other questions, do not hesitate to ask.

This is not possible. We are using UI Virtualization which means that the items are updated at runtime, while scrolling for example. To use it from a button add a conditional property for this and refresh the controls with the following method:
private void RadButton3_Click(object sender, EventArgs e){ var view = radChat1.ChatElement.MessagesViewElement as ChatMessagesViewElement; view.Update(ChatMessagesViewElement.UpdateModes.RefreshAll);}I hope this helps. Should you have any other questions, do not hesitate to ask.

Hello again and thanks for your reply.
I don't see how this can achieve the desired behavior as I cannot access the NameLabelElement by using this "var view = radChat1.ChatElement.MessagesViewElement as ChatMessagesViewElement;"?

The behavior is what I am looking for indeed, but I'm trying to implement the behavior on the chat 'SendMessage' event. The problem is that the AutoAddUserMessages property has to be set to true, and by doing that this solution seems to be excluded to me.I know the chat is not designed for real-time chat, but I think it's very hard to work with it in that relation because of asyc blocks, and the fact that many properties can only be set throw events. But thanks for your answer.
This is done for performance reason and to separate the UI from the actual data. Since R3 2018 we exposed a UserData property in all message types. You can use this property to pas any additional information and then parse it when the message is received and set the visual properties as well.
Let me know if I can assist you further.

Hello again,
Yes that makes sense - I've been noticing the UserData property, but I couldn't find any documentation on it. Can you please provide a short example code?
Thanks in advance.
