I've seen the examples showing how to use
for the GridDropDownColumn, but it seems these examples simply do a lazy load of the list and don't allow for auto complete type lookup from the user.
What I am getting at, if they lookup contains 100,000 items, I don't believe there is a way to used the built in load on demand features to allow the user to type a few characters and get back only the items that match their search.
As a work around we've been using a item template with a RadComboBox and the
option used to query the database with the users typed in value as the search parameter.
I am just writing to verify that there is no simpler way to do this with the GridDropDownColumn.
