FIX. RadDropDownList - slow performance when adding items via the Add/AddRange methods of the items collection
Executing AddRange/AddRange in a Begin/EndUpdate section for 8500 items takes 37 seconds. Add takes 1:08 without Begin/EndUpdate.

For comparison a grid without Begin/EndUpdate takes 52 seconds for 8500 rows, and with Begin/EndUpdate it takes 0.4 seconds.
