QuestionListbox colours. Pin
Septimus Hedgehog26-Feb-13 8:35

I've implemented owner drawing when adding items to a listbox. I won't waste time going into it but where I have hit a problem is with colours. Our application will read a column containing an ARGB value for a colour. This value is put into the Color.FromArgb method which returns a Color object which is then applied to the listbox value. If I use exclusively named colours like Color.Red, Color.LimeGreen that sort of thing the listbox is drawn 100% fine. But if the ARGB value isn't a named colour it fails to render anything. It effectively leaves me with white text on a white background.

Has anyone used other than named colours when painting listbox items using OwnerDrawVariable?

As I say, it works perfectly for named colours but the moment I use an ARGB value which isn't a named colour it doesn't actually do anything.

There is a method in the graphics object called GetNearestColor. I tried pumping my ARGB value into it but the Color object it emits is exactly the same as what I sent it. In other words, it doesn't convert a colour that's approximately "slightly like fuschia" for example into Fuschia which is what GetNearestColor is supposed to do. The colour that's in the database is selected by users with the colour picker dialog and they can select any colour or pick one of their own.

Curiously, the same ARGB value works perfectly in a Treeview control.

Any ideas?
