The AccordionControl features the built-in search panel. Set the AccordionControl.ShowSearchControl property to true to display the search panel.

Accordion items are filtered based on their AccordionItem.Header property value.


By default, the AccordionControl uses the Contains filter condition to construct filter criteria. Use the AccordionControl.SearchControlFilterCondition property to specify another filter condition.

The AccordionControl.SearchControlNullText property specifies a string that the search box displays when it is empty and not focused.

Expanded Search Tag

You can specify a search tag for an accordion item using the AccordionItem.SearchTag property.

Accordion item whose AccordionItem.SearchTag property meets filter criteria is included in search results regardless of its AccordionItem.Header property value.


The search tag is only supported when items are defined explicitly (i.e., not generated from a data source).

The following example demonstrates a data editor explicitly wrapped in an AccordionItem object.

Expanded Data-Bound Accordion Control Filtering

The data-bound AccordionControl is filtered based on the data source values.

The Search Control feature does not support BindingList.


To learn more about data binding, see the Data Binding documentation topic.

There are several ways to configure which data source fields are displayed by accordion items. Depending on this configuration, the item matching rules may differ. Examine the following table.

Binding type Matching rules
AccordionControl.DisplayMemberPath An item is included in the results if the displayed value of the underlying data object meets the search criteria.
Data template An item is included in the results if the ToString() return value of the underlying data object meets the search criteria.

To provide custom filtering logic for the AccordionControl, handle the AccordionControl.CustomItemFilter event.
