Unresponsive UI when using BeginInvoke
- by Kazoom

I have a networked application written in C#. my server program has a UI and several communication threads, that read from tcp sockets and display messages on controller UI.
Communication with each client is done through a seprate thread. When i recieve some stream of messages from one client , the thread for that client writes on UI, which is a richtextbox on a Form.
I call SetTextHelper(string text) method of the form.
which looks like this
private delegate void MyTextUpdateHandler(string text);
public void SetTextHelper(string text)
{
BeginInvoke(new MyTextUpdateHandler(SetText), new object[] { text });
}
public setText(string text)
{
richtext.Text= text;
}
Question
- If i use BeginInvoke my UI is entirely unresponsive when i m writing large stream of data to UI
- Invoke solves that problem, but i read that for multi threaded environment where many thereads are sharing same resource Invoke can lead to deadlocks I share the common ichtextbox between around 16 threads
- What would be a good desing for my situation?
