.Net CF: ComboBox.Text setting fails to match exact list item

Compact Framework ComboBox issue. I have several items in the list, 2 of them are "M3" and "m3". When using ComboBox.Text="m3" in code, value only matches "M3". It's matching the first letter without regard to exact match or case.

ComboBox doesn't have the auto-complete settings in CF as far as I know. DropDownStyle is DropDownList. I tried DropDown but it doesn't work consistently, plus I need it as a list. I also tried SelectedValue.
