Filtering
The MultiColumnComboBox provides a built-in filtering mechanism, a server-side filtering functionality, and a filtering directive.
Basic Configuration
To enable the filtering functionality, set the filterable property to true.
On every user modification of the input value, the MultiColumnComboBox triggers a filterChange event. The event argument contains the typed string value that you can use to filter the source.
The following example demonstrates how to handle the event manually and filter the data in your code. Notice that the filtering is performed against all fields displayed in the popup table.
Built-in Directive
When the entire set of data is available on the client, you can also use the built-in kendoDropDownFilter directive to filter the data on user input. To configure the kendoDropDownFilter directive, provide a DropDownFilterSettings object to it.
The settings object allows you to configure the following options:
operator—Specifies the operator which is used to perform the filtering. Currently, the filtering directive supports thestartsWithandcontainsoperators.caseSensitive—Specifies whether case sensitivity will be acknowledged. By default, the directive will perform case-insensitive filtering.fields—Specifies against which fields the filtering will be performed. If nofieldsare specified, filtering will be performed against the providedtextField.
It is optional to provide the
DropDownFilterSettingsconfiguration object. By default, thekendoDropDownFilterdirective performs a case-insensitive search with thestartsWithoperator against the providedtextField.
Server-Side Filtering
The following example demonstrates how to use the filter value to create the appropriate query string, required for filtering the data on the server.
