Solution 1

The application bar consists of a Buttons collection and MenuItems collection.Try something like..

C#

foreach (var button in ApplicationBar.Buttons)
{
    ((ApplicationBarIconButton) button).IsEnabled = false; // disables the button
}

ApplicationBar.IsMenuEnabled = false; // this will prevent menu from opening

It enables and disables all the buttons. If I want to enable or disable just 1 button what should I change.???

Nikhil_Malik 29-Jul-13 15:51pm

please let me know if you find a sol to disable each app button individually

you can use IsEnabled=false property to disable a button or ApplicationBar.Buttons.Remove(object).See more from here:http://stackoverflow.com/questions/13287034/set-visibility-of-applicationbariconbutton-to-false-in-wp7

ridoy 29-Jul-13 15:23pm

can do something like..
ApplicationBarIconButton btn = (ApplicationBarIconButton)ApplicationBar.Buttons[0];

if (btn.Text == "play")
{
btn.Text="pause"; //enable it
}
else if (btn.Text == "pause")
{
//disable it
}
