The (DynamicProperties) item that appears on the Properties window is used for setting property initialization through an XML file named app.config. Dynamic properties allow you to change property values without recompiling the application, for example during or after deployment.

To get started, select a control in the Forms designer, then in the Properties window expand the (DynamicProperties) item. Select the (Advanced) item, then select the browse button (".") that appears in the value column. A dialog is displayed listing properties of the control that can be set through app.config. The app.config file is added to your project if it didn't already have one.

For more information see Configuring Applications Using Dynamic Properties and Creating Your Own Dynamic Properties and Preserve Property Settings in Visual Basic .NET in the MSDN Library.
