Answer 1

AutoCompleteStringCollection autoCompleteList = 
                                            new AutoCompleteStringCollection();
/* copy your datacolumn in to autoCompleteList iteratively here */
txtBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend; /* or just Suggest */
txtBox.AutoCompleteCustomSource = autoCompleteList;

如果使用c＃应用程序，则可以在应用程序中使用此控件。
