I've been trying to create a custom collection that can be bound to a
combobox via the DataSource property, but I can't seem to get it to work.
I've created a class that implements IList, and it seems to work okay on its
own, but when I try to bind it to a combobox, the combobox doesn't show
anything (and it starts having problems repainting itself). The Datasource
appears to contain my custom collection object, but when I ask for its item
count I receive zero when I should be receiving a higher number.
Has anyone tried to do something like this before and succeeded? Maybe
there's just a problem with my implementation of IList? I can post my code
(it's long) or email it if anyone wants to see it.

Just base your collection on CollectionBase and fill in the appropriate
blanks of Add, Remove and indexer.

Okay, I followed the instructions for creating a class based on
CollectionBase. It now binds to a combobox, but the combobox just shows the
class name instead of the value the ToString property returns for each
object. What's up with that?

Okay, I've seen all the examples of using comboboxes on webforms when

to use comboboxes with id/value foreign keys in a smart (but hard!)

I think every developer needs bound comboboxes to store foreign
keyvalues while displaying the user-friendly value as it is stored in
the foreign table, so there must be plenty of you that have found a way
to do so...

Can I use a bound ComboBox for both browsing and editing?
I'm working on a small, standalone database application using Visual
C#.NET 2003 and an Access data file.
In order to keep the number of different screens down to a minimum,
I'm trying to use the same Windows Forms for both browsing and for
updating. This works fine for TextBoxes, but I'm running into
problems with my DropDownLists (ComboBoxes).

I have a routine that creates a series of comboboxes, each of which is

Does anyone have any example code showing how to sort a datagrid that

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
