Cross-thread operation not valid: control 'treeview' accessed from a thread other than the thread it was created on.

On client I have a tree node on right click on deploy command which publishes a file to my  server.
So on clicking the tree node I will check if the tree ode name is the same as of file name if same ok else I will try to update the object name through server reply. Which here means I have got the server reply and trying to setting the "Text" but at the time of setting the text here in my case :

BaseObject.GetNodeText(Me.QueryConfig)

 Is getting executed and throwing me error 
"Cross-thread operation not valid: Control 'Treeview' accessed from a thread other than the thread it was created on
"

If Not OverrideDefaultDisplayText Then
                    Text = BaseObject.GetNodeText(Me.QueryConfig)
                Else
                    Text = BaseObject.GUIDisplayAs
                End If

this all happens inside a method called refresh


Can someone please suggest what I need to do
