Alphanumeric filtering not working

[Mark]

I am using the RadComboBox to display a list of employees, along with their employee numbers (in the same field, in parentheses). The employee numbers have a fixed two character prefix ("NB") followed by 6 digits ("NB000342", "NB191561", etc). So the field in the combo drop down looks like "Smith, John (NB117654)". I am loading the full list on-demand. The filtering works fine until you type a digit, then it returns nothing. It matters not whether you type only digits or whether you mix digits and text; the presence of any digit(s) results in no matches. Is there a setting that I am missing that enables alphanumeric filtering?

Never mind. It was my misunderstanding of how the control worked. I figured it was searching through the full result set, that it was retrieved only once, on initial load, whereas it in fact sends a request for the data each time (in the configuration I am using).

So, it's all fixed now.
