Conditional behaviors

  • Article

In Microsoft Expression Blend, you can use conditional behaviors to link an action to event when a comparison evaluates to True. You can quickly apply conditions to actions by creating and modifying conditions in the Properties panel.

The following conditional behaviors are available in Expression Blend:

  • **CallMethodAction   **Use the CallMethodAction action to call a method on the DataContext of an element when an event occurs.

    For more information about this action, see GoToStateAction.

  • **HyperlinkAction   **Use the HyperlinkAction action to easily browse to a website address when the action is triggered.

    For more information about this action, see HyperlinkAction.

  • **InvokeCommandAction   **Use the InvokeCommandAction action to invoke a command exposed by the data source.

    For more information about this action, see InvokeCommandAction.

  • **LaunchUriOrFileAction   **Use the LaunchUriOrFileAction action to browse to a website or start an application when the action is triggered.

  • **PlaySoundAction   **Use the PlaySoundAction action to play a sound when an action is triggered.

    For more information about this action, see PlaySoundAction.

  • **RemoveElementAction   **Use the RemoveElementAction action to easily remove an element from a logical tree.

    For more information about this action, see RemoveElementAction.

  • **SetDataStoreValueAction   **Use the SetDataStoreValueAction action to automatically adjust the values of your data store at run time.

    For more information about this action, see SetDataStoreValueAction.

SketchFlow conditional behaviors

The following conditional behaviors are available in SketchFlow:

  • **NavigateBackAction   **Use the NavigateBackAction action to navigate back to a screen you were previously viewing. The NavigateBackAction action functions in the same way as the Back button in the SketchFlow Player.

    For more information about this action, see NavigateBackAction.

  • **NavigateForwardAction   **Use the NavigateForwardAction action to navigate forward to a screen you were viewing before navigating back to a previous screen. The NavigateForwardAction action functions in the same way as the Forward button in the SketchFlow Player.

    For more information about this action, see NavigateForwardAction.

  • **NavigateToScreenAction   **Use the NavigateToScreenAction action to specify navigation between screens.

    For more information about this action, see NavigateToScreenAction.

  • **NavigationMenuAction   **Use the NavigationMenuAction action to associate a particular state with a particular screen. This is particularly useful if you are trying to mimic user navigation while preserving the navigation path and visual states that represent the user's interaction with a navigation menu.

    For more information about this action, see NavigationMenuAction.

  • **PlaySketchFlowAnimationAction   **Use the PlaySketchFlowAnimationAction action if you want to play a SketchFlow animation in response to a user's interaction with your prototype.

    For more information about this action, see PlaySketchFlowAnimationAction.

  • **RemoveItemInListBoxAction   **Use the RemoveItemInListBoxAction action to demonstrate removing an item from a list box.

    The RemoveItemInListBoxAction action works only inside a data template, and only to remove the list-box item that it is associated with from the from the data-bound list box in which it resides.

    For more information about this action, see RemoveItemInListboxAction.

Note

You can use all of the behaviors in available in Expression Blend in SketchFlow projects. However, SketchFlow behaviors are available only in SketchFlow projects.
