Hello, 

I would like to remove all messages of radchat after inactivity.

I don't find how to remove all messages. Could you help me ?

Thanks

Thomas

Hi,

Im using conversationalUI in a WPF app and would like to update the message in realtime as my openAI response is streaming in to make the UX a better experience on long responses. This should update the message being displayed in realtime as the service is streaming in text.

I only see the ability to do a message.Add() option, I feel like there should also be a AddAsync() method. Is this even possible in this control? 

Thanks in advance!

I am creating a little chat demo, by having two chat boxes next to each other (they communicate to each other). My issue is, when I load older messages from the database, I could not properly set a different "current author" for each chat box while maintaining MVVM structure (what I need is: in chatbox 1 user1 is the currentAuthor, in chatbox 2 user 2 is the currnetAuthor)

I am following an MVVM pattern. Code snippets are provided below (I tried to remove all lines irrelevant to the question):

1- my chat boxes

<telerik:RadChat x:Name="chat1" 
			 Width="400"
			 Height="550"
                         DataSource="{Binding Chat1Messages}"
                         CurrentAuthor="{Binding Chat1CurrentAuthor}">
</telerik:RadChat>

 <telerik:RadChat x:Name="chat2" 
			 Width="400"
			 Height="550"
                         DataSource="{Binding Chat2Messages}"
                         CurrentAuthor="{Binding Chat2CurrentAuthor}">

</telerik:RadChat>

2- My code in adding the messages from DB:

//some code to get data from DB//


this.chat1CurrentAuthor = this.FirstAuthor;
this.chat2CurrentAuthor = this.SecondAuthor;

//Iterator over data from DB
{
     //if message is written by first author:
     {
          this.Chat1Messages.Add(new TextMessageObject() { Text = row.MessageText, MsgAuthor = this.FirstAuthor, CreationDate = row.Time });
          this.Chat2Messages.Add(new TextMessageObject() { Text = row.MessageText, MsgAuthor = this.FirstAuthor, CreationDate = row.Time });
     }
     //if message is written by second author:
     {
          this.Chat1Messages.Add(new TextMessageObject() { Text = row.MessageText, MsgAuthor = this.SecondAuthor, CreationDate = row.Time });
          this.Chat2Messages.Add(new TextMessageObject() { Text = row.MessageText, MsgAuthor = this.SecondAuthor, CreationDate = row.Time });
     }
}

3- code to support MVVM:

public Author Chat1CurrentAuthor
{
            get { return this.chat1CurrentAuthor; }
            set
            {
                if (value != this.chat1CurrentAuthor)
                {
                    this.chat1CurrentAuthor = value;
                    OnPropertyChanged(() => this.chat1CurrentAuthor);
                }
            }
}
public Author Chat2CurrentAuthor
{
            get { return this.chat2CurrentAuthor; }
            set
            {
                if (value != this.chat2CurrentAuthor)
                {
                    this.chat2CurrentAuthor = value;
                    OnPropertyChanged(() => this.chat2CurrentAuthor);
                }
            }
}

With my current code, both authors are set up as current authors in both chatboxes (i.e in chatbox1, currentAuthor is both user1 and user2, in chatbox2 currentAuthor is both user1 and user2) which is not the desired behavior.

Dear Team,

I am facing issue with Chat Control. When I tried to change datasource of control, Messages in Chat UI does not reflect.

I have List of User in listbox. Each User has Observable collection of TextMessages. When User selection changed, I bind datasource to selected user messages. I assume that Chat control will update its UI by selected User messaged. But it is not working.

I tried to clear MessageListItems on selection change, and re-bind datasource to selected user's messages. In this case Chat UI does not show any messages.

For reference I have uploaded my sample project on Google drive.

Messenger App

@Admin: I had already shared the same issue few days ago, but i did not receive any solution.

Dear All,

I am new to Chat control. I am practicing RadChat in Chat application, such that I have list of contacts on Left side, which bounded to List of users where

I have bounded RadChat DataSource as SelectedUser.Messages property, where SelectedUser is public property in my viewmodel, which contains selected item object.

As I assume that RadChat need to updated Messages as datasource is changed, but instead of refreshing messages, it appends new messages to old one.

My requirement is to Clear all messages in Chat UI, as I have selected new Messages object as datasource.

Here I want to clarify that data in Messages are correct according to my need. I feel it is some issue in RadChat or I need further steps to acheive my target.
