I have read all the posts on the combo box long load times. Here is my issue:

1. I have a ComboBox with a list of Custodians in it.
2. I scan an Asset tag to look up its details.
3. The ComboBox selects the Custodian from the Asset details.
4. If there is no Custodian, the ComboBox displays '--No one assigned--'.

Here's the problem:

1. There are 1500+ Custodians in the list! = super long loads, memory usage
2. My user needs it to be dummy proof. = I don't want another form to do
the change.
3. I do have a foreign key for the custodian to filter it by their section.
However, these still have 200 - 300 people.

If you are using databinding, stop. Do it manually. Even 200-300
is a lot for a drop down for a mobile device. I can just imagine how
rough it will be to use a stylus with such a small scroll bar.

Are you sure a combobox is the right ui choice for this type
of selection process?

Well, I added a new form to do the custodian transfer. There are 60 sections
and at most there are 300 employees in that section. I put the section list
into a combo box and based on the selected value, a datagrid is populated.
This has made the process a little quicler.

Is there some other control I could be using? I could add a text box to
allow for entering the start of the name, then reduce the result set? Then I
start running into limited screen space. Or, a wizard type search where on
the first panel they choose the section then on the next they filter the
name, then on the 3rd they see the results?
