Examples

The following code example demonstrates how to access the Verbs property for a custom Web Parts control. This example assumes the use of a custom control, TextDisplayWebPart, created in the Example section of the WebPart class overview.

Note that for the code example to work, you must add a setting in the Web.config file to enable exporting Web Parts description files. Ensure that you have a Web.config file in the same directory as the Web page for this code example. Within the <system.web> section, make sure there is a <webParts> element with an enableExport attribute set to true, as in the following markup.

<webParts enableExport="true">

...

</webParts>

Load the Web page in a browser. When you click the Display Verb Count button, it accesses the Verbs property to get the count of custom verbs for the TextDisplayWebPart control, and displays the count in a label. Because no custom verbs have been added to the control in this case, the count is zero.

Remarks

Verbs derive from the WebPartVerb class, and provide user interface (UI) actions that users can perform on a WebPart control. Usually verbs are represented in the UI as buttons, links, or menu items. By default, common Web Parts verbs appear on a drop-down verbs menu in each WebPart control's title bar. There are standard verbs for opening, closing, editing, and minimizing a control, and other verbs for exporting a definition for the control or loading a Help file. These verbs are not included in the Verbs collection, because the collection contains only custom verbs that you create and return by overriding this property in a derived class.

When you create custom verbs and add them to the Verbs collection, you can then access the verbs programmatically from a WebPart control.

Notes to Inheritors

Derived classes can override the Verbs property to allow users to add custom WebPartVerb objects to the verb collection for a WebPart control.
