Hello Friends,

I am working on a website and my requirement is that i need to restrict "Comment Textbox" for entering not more than 250 Words. I applied multimode property on that textbox due to this maxlength property is not working. So i used Regular expression validator to put the restriction. Now i need a regular expression that limits the user to enter not more than 250 words. Please help me in this one. Thank you.

Solution 1

Try limiting to a number of characters instead (which is more reasonable from a storage standpoint): http://stackoverflow.com/questions/6111593/asp-text-box-limit-number-of-characters[^]

Solution 4

Assuming that the definition of a word is one or a group of character(s) that is space delimited, then you may want to just count the number of words using the string split function

C#

    string s = "hello world  1   2  3  ";
    System.Diagnostics.Debug.WriteLine(GetNumWord(s)+ " words");

int GetNumWord(string s)
{
    var words=s.Split(new char[] {' '},StringSplitOptions.RemoveEmptyEntries);
    return words.Length;

}

In the above test, the output is 5 words, extra spaces are ignored.
