Manoj Bhatt 2020 29 Jan 2014

I've two applicationbariconbuttons, out of which one is to be enabled only if certain conditions are met. My Code in C#

if (//conditions)
  {
     ((ApplicationBarIconButton)DeleteButton).IsEnabled = false;
  }

But while excecution, i get the following error,

An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in System.Windows.ni.dll

Help me to solve this one.

Thanks in advance

Hi Manoj,

Use like that

 ApplicationBarIconButton myAppIconButton =
(ApplicationBarIconButton)ApplicationBar.Buttons[0];
 myAppIconButton.IsEnabled = false;

And you will disable it.
