The WindowSearchCustomFilter type exposes the following members.

Constructors

	Name	Description
	WindowSearchCustomFilter	Creates a new instance of a search filter with an apply-filter method for use by the search control for window search.

Top

Properties

	Name	Description
	DisplayText	Gets or sets the display text for the search filter (Inherited from WindowSearchFilter.)
	Tooltip	Gets or sets the tooltip text for the search filter (Inherited from WindowSearchFilter.)

Methods

	Name	Description
	ApplyFilter	Override this method in derived classes to provide specific implementation for the custom filter, by manipulating the search text from the search control and changing the selection as needed.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

Search filters appear as push buttons in the search control’s popup.

Simple filters such as those implemented by WindowSearchSimpleFilter automatically append the filter token (FilterField:DefaultFilterValue) to the search control text.

This class is used to implement advanced filtering of the search control text, since the user has full control over the search field and the selection to be set in the search control after the filter is applied.

Custom filters are used to avoid adding multiple filter tokens with the same field. Custom filters are also used to select the filter value if the caret position in the search control is already within a filter token.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
