How do I make the arrow show up??

Hi all,

There has been an ongoing thread about listboxes that I started and this was brought up in there but I wanted to break this off to a new topic so that soe new people might take a look.. :)

I am trying to make that little arrow show up in my listboxes column header based on how the column is sorted it at all..

There is no easy way (i.e. setting a property) to do this. You would have to owner draw the header and draw the appropriate image in the appropriat column.

Take a look at this link for more info:

(I know its for the Compact framework, but the theory should be the same.)

Thanks for the link, unfortunatly is is C# also.. Not to familiar with that but I am digging.. Thanks :)

Like i said earlier I am not all that familiar with C# so I appologise if I am missing something, but I do not see anything relating to the arrows.. I see the sorting and such and I think I understand that but nothing on the arrow.. Help.. :eek:

In the OnPaint of the HeaderControl.cs is where he draws the arrows:

Code:

---

                                // Prepare arrow
                                if (header.ascending)
                                        PrepareArrowpoints(header.Left + textRect.Width + 20, false);
                                else
                                        PrepareArrowpoints(header.Left + textRect.Width + 20, true);

                                // draw arrow
                                gx.FillPolygon(textBrush, m_arrowPoints);
