Binding from context menu item to parent control
I have a control, on that control is a command called SaveToClipboardCommand. I want to bind a context menu item command to that command so that when i click it, the copy to clipboard command is executed.
<Control x:Name="Control">
<Control.ContextMenu>
<ContextMenu>
<MenuItem Command={"Bind to SaveToClipboardCommand here"} Header="Some Header" />
</ContextMenu>
</Control.ContextMenu/>
</Control>
The control (for argument sake) is defined like this:
partial class Control
{
private ICommand _saveToClipboard;
public ICommand SaveToClipboardCommand
{
get
{
if (_saveToClipboard == null)
{
_saveToClipboard = new RelayCommand(
x=> SaveToClipboard());
}

}
}
}
I have tried using RelativeSource and ElementName based bindings but both are failing. Is what i am trying to do even possible?
Thanks!
EDIT (after showing how the control is exposed): Well ContextMenu is somewhat tricky, because it's actually not part of the same visual tree. Try doing this:
<MenuItem Command="{Binding Path=PlacementTarget.SaveToClipboardCommand,
RelativeSource={RelativeSource AncestorType=ContextMenu}}"/>
Original answer
Is this command exposed as a public property of the Control? If the command is actually exposed in a ViewModel hanging of the control's DataContext, to do the following:
Command={Binding ElementName=Control, Path=DataContext.SaveToClipboardCommand}
Can you show how this command is currently exposed?
Command={Binding ElementName=Control, Path=SaveToClipboardCommand}
