Examples

The following code example demonstrates the use of the UnauthorizedWebPart control.

The first part of the code example is a custom WebPartManager control that overrides the IsAuthorized(WebPart) method to create custom authorization criteria. Any WebPart control that has its AuthorizationFilter property set to a specific value, or any control that has no value assigned to the property, will be authorized, and controls not meeting these criteria will not be authorized.

The second part of the code example is the Web page that hosts the custom WebPartManager control. There are three static server controls declared within the <asp:webpartzone> element. Although these controls are not actually WebPart controls, they will be wrapped with a GenericWebPart object at run time, so you can treat them as WebPart controls and thus assign values to their AuthorizationFilter properties. Notice that the BulletedList control has its filter set to the value that should enable it to be authorized, according to the criteria in the custom WebPartManager control. The Label control has a filter value that should cause it not to be authorized. The Calendar control does not assign a value to the property, so by default it should be authorized.

The third part of the code example is a setting you must add 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 page in a browser, and notice that the BulletedList and Calendar controls are rendered as expected, but the Label control is not rendered because it was not authorized. Clicking the List WebPart Controls button causes the WebPartManager control to list the IDs of all controls in its WebParts collection. Note that the ID for the Label control is listed, proving that an UnauthorizedWebPart control was added to the page control tree to hold its place, even though the label is not rendered in the page.

Remarks

The Web Parts control set provides an authorization mechanism for determining whether individual WebPart controls can be added to a page. Developers can optionally assign an arbitrary string to the AuthorizationFilter property on a WebPart control. When the WebPartManager control is adding controls to a page, it checks this filter value against criteria set by the developer, by using the IsAuthorized method, and returns false if a control is not authorized.

Note

This mechanism also works with server controls and user controls that are placed in WebPartZoneBase zones, because these controls are wrapped with a GenericWebPart object at run time, and this object inherits the AuthorizationFilter property.

When a WebPart control is not authorized, the WebPartManager control inserts an UnauthorizedWebPart control into the control tree of the page in place of the unauthorized control. An UnauthorizedWebPart control in the control tree reserves the position of the unauthorized control in the page, and prevents any personalization data that a user might have previously applied to the WebPart control from being lost.

The UnauthorizedWebPart control is never displayed on a page in which it is inserted, nor does it appear in the source code for the rendered page. Developers can verify its presence in the page control tree by checking the WebParts property of the WebPartManager control.
