Word boundarys and highlight text using regular expressions

Hi
Can anyone help with this small problem.

I can get the text to be highlighted with a match but I'm trying to use word boundaries so that only whole words are highlighted.

My code is:

highlightphrase = Regex.Replace(highlightphrase, "day", "day", RegexOptions.IgnoreCase|RegexOptions.Singleline);

Problem is the above is highlighting day in holiday which is incorrect.

I've tried using \< but receive an error stating non reconized escape character also tried using \b but still does not work. I'm using C# and running asp.net.

Any help would be appreciated.

Tourist_Search,
Use this :
highlightphrase=Regex.Replace(highlightphrase,"(\\bday\\b)","$1", RegexOptions.IgnoreCase|RegexOptions.Singleline);

That worked OK, should have asked how to acheive results when value is a variable.

FirstWord is variable

highlightphrase=Regex.Replace(highlightphrase,"(\\bFirstWord\\b)","$1", RegexOptions.IgnoreCase|RegexOptions.Singleline);

-What control you use to display the item?

Hi x_com

When I could not get the code to work, I removed it from page.
I tried putting the code inside void PreRender(object sender, EventArgs e), void Page_Init(object sender, System.EventArgs e) and void Page_Load(object sender, System.EventArgs e) but neither work.

Tourist_Search,
You can use OnItemBound event to solve the problem. Have you try it? Sorry for my delay because busy around this few day..
If you got any problem, you can state it clearly and i try to solve it as soon as i can.
