I am writing my first C# Program in Microsoft Visual C# 2010 Express.  From "New Project" window, I select "Visual C#", "Windows Forms Application".  I create two buttons.  When I write the source code for first button, it propagates to source code of second button.  

Why ?

I need both button's source code to be independent of each other.

Could you post the code you have?

By propagate, do you mean to say that you change first code for the first button and the code for the 2nd button changes by itself?

Perhaps you had both buttons selected at the same time (by holding down the shift key when clicking on them) and then you assigned a handler to the Click() event using the lightning bolt icon in the Properties Pane?  This would assign the same click handler to all currently selected buttons.

Yes, I thought changing code for the first button changes code for the second button.  But there is only one source code file for both buttons.

I tried to clean solution before editing and building because I thought there are separate source code files for each button.  But there is only one source code for both button.

Everything is working fine.  Thanks for everyone's help.
