Search a Sharepoint list to populate form field

[Karthi]

I have an infopath form with drop down lists which looks up to values in a
Sharepoint list. The ddl is only showing 100 items and is not sorted. Would
like to add a button to search the list so that the user can copy to that
form field.

With help from Thom Robbins resolved this problem. Changed the number of
items in the AllItems list to a very high number and modified the sorting to
alpabhetic sorting by name. The infopath form Dropdownlist shows all the
items sorted and the user can enter the first few letters and make a
selection. Workaround without using code.
