Hello:
I just started working with Javascript and I ran into an error with Visual Studio stating, "Validation (ASP.Net): Attribute 'onMouseOver' is not a valid attribute of element 'Button'". Basically, I entered onMouseOver="this.style.color='Red'" within the HTML code of a button control. When I run my web project, the mouse over command works just fine; however, the error message is posted.
What should I do to resolve this error or is this error message not critical, since the mouse over command works well?
Thank you,
DFM
