Hello You need to assign properties: TColumnEh.DropDownBox.ListSource = NewDataSource (with NewDataSet) TColumnEh.DropDownBox.ListSourceAutoFilter = True TColumnEh.DropDownBox.ListSourceAutoFilterType = lsftContainsEh TColumnEh.DropDownBox.ListSourceAutoFilterAllColumns = True DropDownBox.ListSourceAutoFilter = True. Enable filtering on typing (And search) DropDownBox.ListSource must refer to the DataSource which DataSource.DataSet a separate DataSet that will filter the data. DropDownBox.ListSourceAutoFilterType = lsftContainsEh To filter and search subtext inside field values DropDownBox.ListSourceAutoFilterAllColumns To filter and search in all columns of DropedDownWindow TColumnEh.LimitTextToListValues Set to False, to allow enter any text in the edit box that doesn't only start with text from display values.

Hello Can you write on what volumes of data it is necessary to test the search in order to understand that the speed of the search is not enough for comfortable work? How many records, how many columns? Or perhaps you can send a Demo project. |
