The DisplayTitle property returns either the current value of the base Title property or, if the control has no title, a calculated value.
The DisplayTitle property is designed to be a read-only, calculated property to get the actual current value of the displayed title at run time. Therefore, you should not attempt to use this property to set a title for a CatalogPart control. To set a title, use the base Title property.
The following code example demonstrates programmatic use of the DisplayTitle property. In the <script> section of the page, the code accesses the DisplayTitle property of DeclarativeCatalogPart1 that is declared on the page. This code shows only the Web page; for the full code required to run the example, see the CatalogPart class overview.
