Question

I need a function which will check for a string in a text. (May be label/textbox text).

The function should check if a particular text exist in it, then if found it should make it bold.

How this should be done?

Answer 1

Assuming you mean ASP.NET then such code will work:

string myString = "The quick brown fox jumps over the lazy dog";
string textToReplace = "fox";
myString = myString.Replace(textToReplace, "<span style=\"font-weight: bold;\">" + textToReplace + "</span>");

Then apply the string as Text of a label. You can’t make text bold inside textbox.

The above example will make the word fox bold.
