CatalogPart Class

Definition

Namespace:

System.Web.UI.WebControls.WebParts

Assembly:

System.Web.dll

Serves as the base class for controls that reside in CatalogZoneBase zones, and that provide catalogs of available Web server controls (especially WebPart controls) that users can add to a Web page.

Examples

The following code example demonstrates the use of the CatalogPart class. Because the class is abstract, it is not used directly in code. However, the example shows how to work with the three derived CatalogPart controls provided with the Web Parts control set to demonstrate common usage scenarios.

There are four parts to the code example:

• A user control that enables you to change display modes on the Web page.

• A Web page, which contains the three CatalogPart controls provided with the Web Parts control set, all declared within a CatalogZone on a Web page. The page also contains a WebPartZone control, with an AdRotator control declared in the zone.

• An XML file that contains quotations displayed in the AdRotator control on the Web page.

• An explanation of how to run the example.

The first part of this code example is the user control that enables users to change display modes on a Web page. You should save this code in a file named DisplayModeMenuCS.ascx or DisplayModeMenuVB.ascx (depending on which language you are using). For details about display modes and a description of the source code in this control, see Walkthrough: Changing Display Modes on a Web Parts Page.

The second part of the code example is the Web page. The page contains a CatalogZone control, and within the child <zonetemplate> element, each of the three CatalogPart controls provided with the Web Parts control set is declared. Some attribute are set on the DeclarativeCatalogPart control, and also in the <script> section of the page, the attributes on that control are accessed programmatically. The control contains one child control that a user can add to the page: a standard Calendar control. The CatalogZone and CatalogPart control will only be visible when the user switches the page to catalog display mode.

The page also contains a WebPartZone control, and within its child <zonetemplate> element is an AdRotator control that displays alternating messages from an XML file. If a user closes the control by clicking its close verb when the page is displayed, the control is added to the page catalog, and the user can reopen the control by switching the page into catalog display mode, accessing the PageCatalogPart control, and adding back the closed control.

The third part of the code example is the XML file. This file is a source file for the AdRotator control that is declared on the page. The file contains favorite quotations, which the control periodically rotates and displays. Copy the following content into a text editor, and save the file as Quotes.xml.

<?xml version="1.0" encoding="utf-8" ?>  
<Advertisements>  
  <Ad>  
    <AlternateText>  
      A stitch in time saves nine.  
    </AlternateText>      
  </Ad>  
  <Ad>  
    <AlternateText>  
      A penny saved is a penny earned.  
    </AlternateText>      
  </Ad>  
</Advertisements>  

To run the code example, load the Web page in a browser. Use the Display Modes drop-down control to select Catalog and switch the page to catalog display mode. Notice the effects of the various property values that were set on the DeclarativeCatalogPart control that contains the Calendar control. You can select the check box next to the Calendar control, and click Add to add it to the page. If you click the Display DeclarativeCatalogPart Properties button, the values of the properties for that control are displayed. You can click Close to return the page to normal browse mode and see the added control on the page. Now go to the verbs menu on the AdRotator control (represented by the downward arrow in the title bar) and click Close. The control is closed and added to the page catalog. Switch the page into catalog display mode again, and click the Page Catalog hyperlink to display the PageCatalogPart control. Note that the AdRotator control is referenced there by its title, Favorite Quotes. Select the Favorite Quotes control, and click the Add button to add the control back to the page. Click the Close button to return the page to browse mode.

Note

The ImportCatalogPart control is also declared on this page, but a sample showing how to import controls is more involved, so full use of the control is not demonstrated in this code example. To see a full working example, see the class overview documents for the ImportCatalogPart class or the CatalogZone class.

Remarks

The CatalogPart class is a base class for special controls that reside in CatalogZoneBase zones. These derived CatalogPart controls provide catalogs of Web server controls that end users can add to a Web page. Use CatalogPart controls in a Web application when you want to provide end users with the flexibility to change the functionality of a Web page by adding or removing server controls.

A catalog is simply a list of one or more available Web server controls (including WebPart controls, ASP.NET server controls, and custom or user controls) that users can add to a Web page. A catalog has a number of common characteristics, including instruction text for end users; text to describe each server control; helper controls to select the server controls and add them to the page; a common header, footer, and border; and a number of style attributes.

There are three types of CatalogPart controls provided with the Web Parts control set, as described in the following table. Each type of CatalogPart control contains server controls that are added to a page from a different source.

Important

Controls that inherit from the CatalogPart class can reside only in zones derived from the CatalogZoneBase class.

Control	Description
PageCatalogPart	Contains controls that have been closed on a page, and that can be reopened (added back to the page) by users. The controls in this type of catalog are controls that were already added to the page from another source, and were then closed by a user.
DeclarativeCatalogPart	Contains server controls declared within a DeclarativeCatalogPart control, which is itself contained in a CatalogZoneBase zone in the markup of a Web page.
ImportCatalogPart	Provides the user interface (UI) for a user to upload a control's definition file (an XML file defined by a schema, that contains state information) to a catalog, so that the control can be added to a Web page. The controls themselves do not appear in this type of catalog; the catalog is just a mechanism for accessing the definition files for external controls so they can be added to a page.

The CatalogPart class inherits from the base Part class, so that it has the common behavior of other part controls in the Web Parts control set. In addition, it adds some members that are useful for the catalog functionality. The DisplayTitle property gets the actual string that is currently being displayed as the title of the control. The value of this property can be the same as the value of the Title property or, if no value has been assigned to that property, a default value supplied by the .NET Framework. The WebPartManager and Zone properties both provide convenient access to the two essential objects that control the life cycle of a CatalogPart control: the WebPartManager control, and the CatalogZoneBase zone that contains the CatalogPart control, respectively.

The CatalogPart class also contains several methods. The GetAvailableWebPartDescriptions method is declared as an abstract method that must be implemented by inheritors. Its intended purpose is to return a collection of descriptions of the controls in the catalog. A related method, GetWebPart, is also declared as abstract and must be implemented by inheritors. This method is intended to return an instance of a WebPart control based on a description that is passed to the method as a parameter.

Notes to Implementers

Because the CatalogPart class is abstract, you cannot use it directly on a Web page. The Web Parts control set provides three CatalogPart controls (listed in the table in the Remarks section of this topic) that derive from the base class and that can be used on Web Parts pages. These controls should provide most of the features needed to create catalogs of Web server controls. However, you might have specialized needs that would require developing a custom CatalogPart control. For example, you can create a special type of CatalogPart control that makes server controls available through a Web service, or directly from a database. To do this, you must inherit from the CatalogPart class. You must also override the abstract GetAvailableWebPartDescriptions() and GetWebPart(WebPartDescription) methods to provide an implementation that returns the WebPart or other server controls, and their descriptions. You will also need methods to load the various server controls from your database or Web service.
