Options

The TreeList.OptionsFind property provides access to options specific to the find panel.

Behavior: Search or Filter

The TreeList.OptionsFind.Behavior property specifies how to show search results:

  • Filter — hides records that do not match the query and (optionally) highlights results within the tree list.

  • Search — highlights results in the tree list and on the scrollbar.

If this property is set to Default, the behavior depends on the static (Shared in VB) WindowsFormsSettings.FindPanelBehavior property. If FindPanelBehavior is also set to Default, the Filter mode is applied.

Highlight Results

To specify whether search queries are highlighted, use the TreeList.OptionsFind.HighlightFindResults property.

Automatically Apply Search Queries

After a user types in the search box, the search starts automatically depending on the underlying data source. You can use use the TreeList.OptionsFind.FindMode property to specify this behavior. If the search begins automatically after a query is entered, the TreeList.OptionsFind.FindDelay property specifies the delay before the search is initiated.

Search Syntax

Search syntax can vary depending on the TreeList.OptionsFind.ParserKind and TreeList.OptionsFind.Condition properties. See the following help topic for more information: Find Panel Syntax.

Parse Search Query

If standard search syntax does not fit your needs or you need to highlight search results in a custom manner, you can handle the TreeList.ParseFindPanelText event. The event allows you to create a filter condition based on the query and specify how to highlight results in the control.
