setting button initial state with condition

SamRideout1

I am trying to create an AddIn with two buttons where the state is controlled with conditions.  This is working but the button state is Disabled on program startup.  I need a way to have one of the buttons Enabled on startup.  I can't seem to find any code to allow me to have the button Enabled on startup.

Success!!   I found the following code and was able to get it to work.

protected override bool Initialize() //Called when the Module is initialized.      
{           
   ProjectOpenedEvent.Subscribe(OnProjectOpened); //subscribe to Project opened event          
   return base.Initialize();       
}        

private void OnProjectOpened(ProjectEventArgs obj) //Project Opened event handler      
{           
   MessageBox.Show($"{Project.Current} has opened"); //show your message box  
   //Put the button code here to activate or deactivate    
}        

protected override void Uninitialize() //unsubscribe to the project opened event      
{           
   ProjectOpenedEvent.Unsubscribe(OnProjectOpened); //unsubscribe          
   return;       
}


Thank you so much for your help..... AWESOME!!!!!!!!!!
