Disable and enable buttons in C#

In your button1_click function you are using '==' for button2.Enabled == true;

This should be button2.Enabled = true;

button2.Enabled == true ; must be button2.Enabled = true ;.

You have a compare == where you should have an assign =.

button2.Enabled == true ;

thats the problem - it should be:

button2.Enabled = true ;
