<format type="text/markdown"><![CDATA[
## Remarks
The <xref:System.Windows.Input.CommandManager> only pays attention to certain conditions in determining when the command target has changed, such as change in keyboard focus. In situations where the <xref:System.Windows.Input.CommandManager> does not sufficiently determine a change in conditions that cause a command to not be able to execute, <xref:System.Windows.Input.CommandManager.InvalidateRequerySuggested%2A> can be called to force the <xref:System.Windows.Input.CommandManager> to raise the <xref:System.Windows.Input.CommandManager.RequerySuggested> event.
## Examples
The following example uses a <xref:System.Windows.Threading.DispatcherTimer> to periodically call <xref:System.Windows.Input.CommandManager.InvalidateRequerySuggested%2A> to force the <xref:System.Windows.Input.CommandManager> to raise the <xref:System.Windows.Input.CommandManager.RequerySuggested> event.

## Remarks
This event holds onto the handler as a weak reference. Objects that listen for this event should keep a strong reference to their event handler to avoid it being garbage collected. This can be accomplished by having a private field and assigning the handler as the value before or after attaching to this event.
