Item doesn't show text on selection

Hi guys,

I have a problem with the combo box I'm writing on.
What I want is custom items, which are fine so far, but when I select
one the combo box shows the project name
("WindowsApplic ation1+ListItem s")... What's wrong? The source code is below.

Thanks in advance!

Best regards,

HKSHK

Probably beacuse you're shadowing the ToString method in the ListItems
class. Try overriding it instead

I've got a function, you can see it below, that is being called onmouseup in the textarea on my main form. The idea is to find a selection if possible and store that text in a global variable. I can't get this to work in any browser on a Mac, though it works alright on a PC. What am I missing?

Hi, On an ASP.NET page I have a drop down list control.

Or is there a drop down control "revert" method, or is there any way of knowing what the original...
