I have a text box that I need to validate so that only alphanumeric values and spaces can be entered. Can anyone please tell me what exact regular expression I should use?

Hi, I noticed your title was all capitals and this looks very demanding, as though you are shouting, and therefore aggravates other users of the forum. Therefore, I have corrected it for you (and a few spelling problems in your question). Cheers, Ali :)

Try:

"^[0-9a-zA-Z ]+$"
