Re: GetColumn problem

According to the docs for TLP.GetColumn ():

---
The column position of the specified child control, or -1 if the 
position of control is determined by LayoutEngine.

To get the actual position of control, even when its position is 
determined by LayoutEngine, call the GetPositionFromControl method.
---

So if you aren't explicitly setting the control's column earlier in 
code, this will return -1.  If you are relying on the TLP to arrange 
them automatically, you need to use TLP.GetPositionFromControl().
