hi,
i moved from syncfusion 3.2.1.0 net 1.1 to 4.4.0.51 net 2.0 and now have refresh problems with textbox autocomplete.
attached is a sample.
start it, type "king" in the first textbox. you see one row, but it should be 4. if you push the down button several times, you will be able to see 3 rows. with 4.2.1.0 we didn't have this problems.
