Hi everyone, I get tired to looking and don't found a direct answer about how to enable / disable a ribbon button, I'm working by the first time in SharePoint and I don't have any idea of how it works by the controls. I have a Project Sever 2010 and what my client wants is when check a user task the "Remove Task" button been enable if the task is not 100%, but I can't find and easy way or explicit way of how to do that.
Can somebody help me?
Thanks.
