• how can close application (file) menu programmatically?

• how can detect if user opens application menu? didn't found appropriated event

you need isdropdownopen property , related event(s). xaml (this .net 4.5+, 4.0 same, difference in namespace prefix):

<stackpanel>     <ribbon>         <ribbon.applicationmenu>             <ribbonapplicationmenu x:name="menu" dropdownopened="ribbonapplicationmenu_dropdownopened">                 <ribbonapplicationmenuitem header="foo"/>                 <ribbonapplicationmenuitem header="bar"/>             </ribbonapplicationmenu>         </ribbon.applicationmenu>     </ribbon> </stackpanel> 

code-behind:

public partial class mainwindow : window {     public mainwindow()     {         initializecomponent();     }      private void ribbonapplicationmenu_dropdownopened(object sender, eventargs e)     {         // user has opened menu         debug.writeline("menu opened.");         // let's close code         menu.isdropdownopen = false;     } } 

also, may want disable entire menu. can done using isenabled property.
