Solution 4

Rather than executing your code in the KeyPress event, better do it in the Validating event. It will be executed when you validate your textbox (tab or enter) rather than each time you press a key on this control.

Please vote if this helped.

Actually I Need The Code In KeyPress Or TextChange

Singh Vijay Kumar · Answer 2 · 2012-12-05T22:59:00

Solution 1

this can be done with few lines of code only.
Add
using System.Text.RegularExpressions;

Write This Code

var phrase = "Test WORD";
var rx = new System.Text.RegularExpressions.Regex(@"(?<=\w)\w");
var ConvertedValue = rx.Replace(phrase, new MatchEvaluator(m => m.Value.ToLowerInvariant()));

It Works Only On Text Leave Event, But I Need It On KeyPress Or TextChanged Events

AnkitGoel.com 7-Dec-12 3:38am

Please implement KeyPress or TextChanged Event and use the same code in that event-

CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
TextInfo textInfo = cultureInfo.TextInfo;

Console.WriteLine(textInfo.ToTitleCase(title));

The problem your are facing is due to your coding style not because of this code. Please recheck and mark as answer if worked. May be u can send your code here if u need to be reviewed.

Solution 3

Try this

C#

string phrase = txtCName.Text;
phrase = char.ToUpper(phrase[0]) + phrase.Substring(1).ToLower();
txtCName.Text = phrase;

Chaitanya its working in mine case
Might be you are missing something.

Also you can use textbox leave event insteed of key press and then split the text based on space and process words as usual.

C#

//Method One
               var phrase = "Test WORD";
               Trace.Write(phrase);
               var rx = new System.Text.RegularExpressions.Regex(@"(?<=\w)\w");
               var newString = rx.Replace(phrase, new MatchEvaluator(m => m.Value.ToLowerInvariant()));
               //Method One
               string s = "Test WORD";
               StringBuilder sb = new StringBuilder(s.Length);
               bool capitalize = true;
               foreach (char c in s)
               {
                   sb.Append(capitalize ? Char.ToUpper(c) : Char.ToLower(c));
                   capitalize = !Char.IsLetter(c);
               }
               s = sb.ToString();
