ComboBox with multiple columns?

I would like a dropdown list (comboBox) that displays not just one column but two (or more).

I have seen examples that concatenates two values to one, and just displays that. But that is a bit ugly. The separator between the two values wont line up at column boundaries, when you have text of different length in the list. Therefore I would like to avoid concatenating, and actually display two separate values in two separate columns. How do I do this?

Ugly:

  Johnnie | Doe
  John | Smith

Nice:

  Johnnie | Doe
  John    | Smith

Edit: I went with a ListView instead of a dropdown list. It supports multiple columns cleanly.

You would have to build the combobox programmatically and have the strings written out (or build a custom method to do so) in such a way that your divider is always at the same location.

Probably something like get the longest length of first name, add 1, then do a string replace with enough spaces to fill before the separator in each name that is shorter.

You'll have to do an ownerdraw for this ... see ComboBox.DrawMode Property for an example of how to go about it.
