Hide or disable Input Gesture Text in wpf - wpf

Question

Say we're using "Ctrl+S" input gesture for saving the project.
In File menu - "Save Ctrl+S" such text is displayed.
Now on canexecute of SaveCommand I check whether project required save or not. If it doesnt require then Save is disabled.
In that case I see menu item like " Ctrl+S" . I've to hide this input gesture text also.
Ideas?
Any new feed ??
This question got no love :( ...

Answer 1

Finally i found a fix. Overrided the default template of Menu Item and added a trigger that whenever Menu Item is disabled, change the color of Input Gesture Text to look like disabled.
Here is the overriden template and the last trigger does the above mentioned issue i mean color change..
<ControlTemplate x:Key="{x:Static MenuItem.SubmenuItemTemplateKey}"
TargetType="{x:Type MenuItem}">
<Border x:Name="Border"
TextElement.Foreground="{DynamicResource SubMenuItemTextForegroundColor}"
Background="{DynamicResource FileMenuBackgroundBrush}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"
SharedSizeGroup="Icon" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto"
SharedSizeGroup="Shortcut" />
<ColumnDefinition Width="13" />
</Grid.ColumnDefinitions>
<ContentPresenter x:Name="Icon"
