How to move messagebox messages to list

Question

I have an application in which i am generating status messages frequently. I am printing all these messages to message box. Instead of using message box i want to use list box or multi line text box . How should i proceed.

void client_MqttMsgPublishReceived(object sender, MqttMsgPublishEventArgs e)
{
    publishstatusTextbox.Items.Insert(0, DateTime.Now.ToString("hh:mm:ss:fff") + "MessageID=");
}

I'm getting following exception

cross thread operation not valid "publishstatusListbox" is accessed from the thread other than the thread it was created on

you would want to do something like this that will group all of your error and then put them all in one message box.

var errors = new List<string>();

try
{ 
    //your code here 
}
catch(Exception ex) {
    errors.Add(ex.InnerException.ToString());
}

var sb = new StringBuilder();
foreach (var errorMessage in errors)
{   
    sb.AppendLine(errorMessage);
}

if (errors.Count > 0)
{
    MessageBox.Show(sb.ToString(), "Errors Present", MessageBoxButton.OK, MessageBoxImage.Error);
}
