Overview
The user can filter the content of a Table control by displaying the records corresponding to a condition for example.
Table control filter options
Remark: These filter options are also available for TreeView Table controls.
How to?

Filter on a column

This feature is automatically implemented in Table controls populated programmatically and in Table controls based on a data file, for columns with search (magnifier displayed in the column). Simply right-click the search icon to open the context menu of the column:
Filter on a column
For managing filters, this context menu proposes:
  • to implement a filter ("Filter"):
    To do so, select a condition and type the requested value. The content of the Table control is filtered according to the specified condition.
    Remark: The "Is empty" condition is used to display only empty elements in the column.
  • to set a filter with one of the values in the column.
  • to delete a filter that was previously set on the column ("Delete filter").
  • to remember filters ("Remember filters").
    If this option is enabled:
    • the filters implemented when closing the window will be automatically run during the next window opening.
    • A short message will be displayed to inform the user and to indicate the filters that are set.
      • The display duration of this message can be configured by AAFConfigure.
      • The toast does not lock the application and can be closed with a simple click.
Remarks:
  • The context menus displayed when you right-click the column title and the search icon are different. For more details on the options of this context menu, see Context menu of columns.
  • In a multilingual application, you have the ability to translate the context menu, see Configuring the menus of AAFs.
Managing the filters through programming

Proposing a filter through programming

TableEnableFilter is used to create a filter on a column through programming. This filter can be disabled by TableDisableFilter.
TableFilteredColumn returns the list of columns filtered by the user.

Don't propose the context menu for implementing a filter on the columns

To avoid proposing the context menu for implementing a search and a filter on the columns, use AAFDisable associated with the aafFilter constant.

Storing filters

The StoreFilterAAF property is used to determine and specify if the filters set by the user on a Table control are saved when an application is closed and opened again.
When AAFConfigure is used with the aafToastDurationRestoreFilter constant, it allows you to define the amount of time a toast message appears on the screen to indicate the users that a filter has been set.
If you don't want to show the "Remember filters" and "Remember sorts" options in the context menu, simply use AAFDisable with the aafSaveFilterAndSort constant.
