Don,

I guess my point was that because you set the DisplayMember as you did (using the Bound table instead of the DataSource), perhaps *that's* what's keeping it from working correctly with the hand-typed value. At least that was my original point, but now that I think about it, it's probably because what you're typing in is the DisplayMember, but because you're typing it in there, you're not giving it any kind of corresponding value to go with it.

IOW, say you're displaying state names and your value is the two character state abbreviation. Even if you type in a two character abbreviation into your combo box, it's probably being interpreted as the DisplayMember and not the ValueMember. I'm probably not explaining it too well and I may even be wrong.

I haven't used a ComboBox in this manner, so I don't know if I'm all that much help. Maybe someone else could jump in here and help out.

>Thanks Bonnie, but I don't seem to have any problem using an arraylist if I use the sample from the Help screens that creates individual State objects with properties, then add thos objects to the "States" Arraylist. That part seems to work fine, I just want to know how to store hand-typed values. You see what I mean - like when you use the keyboard to type into the combobox rather than picking an item from the dropdown list with the mouse.

>>Typically the .DisplayMember will be from the DataSource, not from the Bound data. I'm assuming that you did it this way because your arraylist has only one dimension. I've not found an easy way to use an array as a DataSource when your DisplayMember and ValueMember are two different things (I may be missing something) ... in those cases, I've just built a Table instead of an Array and used the Table for the DataSource.
