Hi,

If I want a button non-clickable until a link above the button is
clicked(i.e., an legal informational page is viewed then a user can go on to
the next page by clicking the button), how can I implement it?

thanks,
 
This any good for you?

You can also achieve the same result using javascript, avoiding
postback an improving user experience.

On link click:

ClientScript.RegisterStartupScript(this, "document.getElementById('" +
Button1.ClientId + "').enabled = true;", true);
