You cannot tell if an object has been changed using an ObservableCollection. The way to do this is to use INotifyPropertyChanged and raise the PropertyChanged event whenever you change the value in a property.
A ListBox has display strings those are the ones you see in the GUI and associated with each of these display strings is a value. So the DisplayMember of ListControl gives you the string as you see it in your GUI and the ValueMember property of ListControl (ListBox is derived from ListControl)...

That is the way that Windows works. Your repeated calls to moveform is preventing the updates from getting actioned until the loop terminates, and you start pulling messages from the queue.

Now there are many listbox or listctrl control use process bar ,combobox ...as item;but i want a list control use dialog as item,Is there somebody had seen this kind of control?can u give me a url?thank u!

This seems rather odd for an UI. If you just want to show a read only dialog there, you may not need to embed a dialog. Instead use custom drawing/painting to show all the data you want to, and make it look like a dialog.On the other hand if you want to get an editable dialog in there,...

It is probably the InsertColumn call that is spoiling your game. At the second call of displaytext you insert a new column, thereby shifting the existing column to the right and out of view. That is why you don't see the first value any longer.Place that InsertColumn call in your dialog...
