How to: Use Extensions in a LightSwitch Project

You use different types of extensions in different ways. Custom data type extensions appear in the Type list in the Data designer when you choose a compatible data type. For example, the Image custom data type extension becomes available when you choose the Binary data type.

Custom control extensions appear in Screen Content Tree lists in the Screen designer. For example, a custom Masked Edit control appears wherever a TextBox is available. The following procedures describe how to use theme and shell extensions.

Extensions are available only if they're enabled in the Extensions tab of the Application designer. See How to: Add or Remove Extensions.

To apply a theme extension

  1. In Solution Explorer, open the shortcut menu for the Properties node, and then choose Open.

    In the Application designer, choose the General Properties tab, and then choose the Edit Client properties link.

  2. In the Theme list, choose the extension that you want to apply.

To apply a shell extension

  • In the Client designer, choose the Client Properties tab, open the Shell list, and then choose the extension that you want to apply.
