Defines identifiers for a set of technologies that designer hosts support.
Syntax
public enum ViewTechnology
Remarks
The view adapter model replaces and adds functionality to the System.ComponentModel.Design.ViewTechnology feature; however, the System.ComponentModel.Design.ViewTechnology feature is retained for both backward compatibility and future use, if you choose. For more information, see ".NET Shape Library: A Sample Designer" in the Windows Forms Knowledge Base at http://windowsforms.net/articles/shapedesigner.aspx.
System.ComponentModel.Design.ViewTechnology defines identifiers that can indicate the mode to use for controlling the display of a designer-hosted document.
You should only use the ViewTechnology.Default value in your designer hosting environment. In previous versions of the dnprdnshort, the System.ComponentModel.Design.ViewTechnology enumeration specified the type of UI model supported by a root designer. Because this model is not extensible, you should instead use a view adapter model. A view adapter is a type that adapts an object of one type to another.
For example, an HTML designer might return a DemoDOM tree as its view. The HTML designer returns a view technology of ViewTechnology.Default. A Windows Forms hosting environment would have one or more view adapter classes available. If one such class could convert the DemoDOM into a Windows Forms control, the hosting application can support this type of designer. If no adapter can handle the data type returned from the designer’s IRootDesigner.GetView(ViewTechnology) method, the load of the designer will fail, and the user will be presented with an error.
vsprvs has an extensible scheme for providing view adapters, so it can adapt to any UI technology. Third-party technology providers can also offer an appropriate view adapter, and their object models are immediately consumable.
For an example that uses view adapters, see ".NET Shape Library: A Sample Designer" in the Windows Forms Knowledge Base at http://windowsforms.net/articles/shapedesigner.aspx.
