IXRVisualTransition::GetFrom (Compact 2013)
3/28/2014
This method retrieves the name of the visual state to transition from.
Syntax
virtual HRESULT STDMETHODCALLTYPE GetFrom(
__out BSTR* pFrom
) = 0;
Parameters
- pFrom
[out] Pointer to a string that identifies the name of the visual state to transition from.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
Specifying a state to transition from, by calling IXRVisualTransition::SetFrom, is optional. A visual transition can be restricted to apply to only certain states, or it can be applied any time that the control transitions between states. You restrict when an IXRVisualTransition object is applied to the control by calling IXRVisualTransition::SetTo and IXRVisualTransition::SetFrom.
The following table describes the levels of restriction, from most restrictive to least restrictive.
Type of restriction |
Value in SetFrom |
Value in SetTo |
|---|---|---|
From a specified state to another specified state |
The Name of an IXRVisualState |
The Name of an IXRVisualState |
From any state to a specified state |
Not set |
The Name of an IXRVisualState |
From a specified state to any state |
The Name of an IXRVisualState |
Not set |
From any state to any other state |
Not set |

You can have multiple IXRVisualTransition objects in a collection that belongs to an IXRVisualStateGroup that refer to the same state. However, they will be used in the order that the table above specifies.
Note
The contents of a ControlTemplate defined in Microsoft Silverlight 3 XAML cannot be accessed from C++. Therefore, visual transitions and visual-state groups that were defined in a ControlTemplate in the source XAML for your application cannot be accessed in XAML for Windows Embedded object tree.
