wpf - Disable other menu items when one of the menu item is clicked c# -

i have simple menu in wpf client c# application user should able select 1 item @ time. if 1 of items selected, other items should disabled until operation completed.

for example, have following menu

 <menuitem header="help">             <separator></separator>             <menuitem header="user manual.." click="usagedocmenuitem_click" />             <separator></separator>             <menuitem header="login"  click="loginitem_click"/>             <separator></separator>             <menuitem header="about"  click="aboutmenuitem_click"/>             <separator></separator>         </menuitem>` 

if user clicks login, user manual , should disabled until operation trigerred login finished.

which c# design or code method can used implement this?

so means there menu items , when user clicks on 1 of them example : login till time action completed login should enabled , other menu items should disabled.

you need create event of button click , within same need write code find other menu items , disable them.

button_click event(...) { //...disable other menu items }
