TextBox Highlight Words Question

[sonya9879]

hi is it possible to hightlight words within a readonly textbox? I written a highlight function to highlight text but the html tags that does the highlight doesn't render in the textbox? I am wondering if is it possible to do this or not? Been trying several different things but didn't work so far.

Can you post the code you have written? Maybe that would give us a clearer understanding of what you are doing and what isn't working.

var = "hello how are you tell me please how"

textbox1.Text = highlight("how",var,"<span class=highlight>", "</span>")


Function Highlight(ByVal SearchWord As String, _
ByVal InputTxt As String, _
ByVal StartTag As String, _
ByVal EndTag As String) As String

Return Regex.Replace(InputTxt, "\b(" & Regex.Escape(SearchWord) & ")\b", _
StartTag & "$1" & EndTag, RegexOptions.IgnoreCase)

End Function


All this works fine BUT in the textbox area I get the <span > tag instead of what I want, the word hightlighted in a different color

You won't be able to do this with a standard Textbox control, however there are quite a few free Rich Text Box controls that will give you this functionality
