Hi Mike,
As for how to format a string value, generally , we can use the
string.Format method to perform simple format, as for our problem, we can
use the following code to format the string:
string num = "800555-1212";
string newnum =
string.Format("({0}){1}",num.Substring(0,3),num.Su bstring(3,num.Length-3));
Response.Write("<br>num: " + num);
Response.Write("<br>newnum: " + newnum);
Here is the reference on "String.Format" method in MSDN:

Also, we can also use Regular Expressions to do string search or
relacement, for example:
function
{
string num = "800555-1212";
string newnum = Regex.Replace(num,@"\d{3}",new
MatchEvaluator(this.Addbracket));
Response.Write("<br>NewNum: " + newnum);
}
protected string Addbracket(Match m)
{
if(m.Index == 0)
{
string x = m.ToString();
return "(" + x + ")";
}
return m.ToString();
}
You can find some other examples on using Regex in .net framework at the
