Need to automatically Highlight the keywords in the text box using code behind c#

Question

Hi

I m retrieving a text from SQL DB based on the Search criteria i give and displaying in the Textbox in asp.net. I need to highlight the words given in the search criteria in the displayed text.

For example : If i give "need" all the word "need" in textbox that is retrieved and displayed should be highlight in yellow color. Provide me some code snippets too.

An asp.net TextBox renders as either an html <input type="text"> or a <textarea> neither of which support formatting of the text inside.

If you were to display the text in a Label or LiteralControl it would be easy to just do a yourString.Replace(searchTerm, "<span style=\"color:yellow\">" + searchTerm + "</span>"); or something similar.
