The Column Chooser allows users to hide and display columns and bands. To display the Column Chooser , a user should select the Show Column/Band chooser option in the column’s header context menu:
The Column Chooser window contains column and band headers and check boxes. Each check box visualizes the BaseColumn.Visible property of the corresponding column or band. Set the BaseColumn.ShowInColumnChooser property to false to hide a column/band from the Column Chooser window.
The table below lists the main properties that affect element behavior and appearance:
| Characteristics | Members |
|---|---|
| Column Chooser Control | ExtendedColumnChooserControl |
| Show and Hide | DataViewBase.ShowColumnChooser, DataViewBase.ShownColumnChooser, DataViewBase.HideColumnChooser, DataViewBase.HiddenColumnChooser, DataViewBase.IsColumnChooserVisible |
| Template | DataViewBase.ExtendedColumnChooserTemplate |
| Column Header Template | DataViewBase.ColumnHeaderTemplate |
| Header Caption | ColumnBase.ColumnChooserHeaderCaption |
The GridControl displays the Column Chooser in a separate window. To add the Column Chooser to the same window as the GridControl, create an ExtendedColumnChooserControl object:
