Change position MessageElement & add list message

[Hai]

I want to change position MessageElement when I want to do it. When I load old message, I only load about 30 message element, then when I scroll to last message I will load 30 next message.

Hello, Hai, 

You can use the RadChat.AddMessage method and load as many messages as you wish. Please refer to the following help article demonstrating how to add messages: https://docs.telerik.com/devtools/winforms/controls/chat/chat-items/messages

It is possible to handle the ChatElement.MessagesViewElement.VScrollBar.ValueChanged event and detect when you scroll the vertical scrollbar. Then, you add the messages you want.

I hope this information helps.
