Dear George,

If you change the bound properties from a thread other than the UI thread,
you should check the InvokeRequired property, if InvokeRequired returns
true, you need to pass a delegate to the Invoke method on the control.  For
example:

       private void Form2_Load(object sender, EventArgs e)
       {
           c = new Customer(1, "Zhang", "China");
           this.label1.DataBindings.Add("Text", c, "Name", true,
DataSourceUpdateMode.OnPropertyChanged);
       }

       Customer c;

       private void button1_Click(object sender, EventArgs e)
       {
           Thread thread = new Thread(new
ThreadStart(setNameFromNonUIThread));
           thread.Start();
       }

       private void setNameFromNonUIThread()
       {
           if (this.label1.InvokeRequired)
           {
               this.label1.Invoke(new MethodInvoker(setNameFromUIThread));
           }
       }

       private void setNameFromUIThread()
       {
           c.Name = "test";
       }

Should you have any questions, please feel free to let me know.

Sincerely,
Zhi-Xin Ye

Note: The MSDN Managed Newsgroup support offering is for non-urgent issues
where an initial response from the community or a Microsoft Support
Engineer within 1 business day is acceptable. Please note that each follow
up response may take approximately 2 business days as the support
professional working with you may need further investigation to reach the
most efficient resolution. The offering is not appropriate for situations
that require urgent, real-time or phone-based interactions or complex
project analysis and dump analysis issues. Issues of this nature are best
handled working with a dedicated Microsoft Support Engineer by contacting
