I want to capitalize every first letter in a textBox text and I want when the user start entering the text it will automatically capitalize first letter...
I tried this -:

C#

private void textBox1_TextChanged(object sender, EventArgs e)
        {
            CultureInfo cultureInfo = System.Threading.Thread.CurrentThread.CurrentCulture;
            TextInfo textInfo = cultureInfo.TextInfo;
            textBox1.Text= textInfo.ToTitleCase(textBox1.Text);
        }

but when the first letter capitalized it set the cursor position at the beginning of the text so the text is reversed..
If I want to enter "jayanta" it shows "Atnayaj" But correct is "Jayanta"..

I want it like, when we set CharacterCasing property to UPPER then it change the text lower to upper case without changing the cursor position in the textBox...

How to fix it??
thanks in advance....

C#

char[] v=textBox1.Text.ToCharArray();
string s = v[0].ToString().ToUpper();
for (int b = 1; b < v.Length; b++)
     s += v[b].ToString().ToLower();

Yes, I know ...
I added it in my code -:
CultureInfo cultureInfo = System.Threading.Thread.CurrentThread.CurrentCulture;
TextInfo textInfo = cultureInfo.TextInfo;
textBox1.Text= textInfo.ToTitleCase(textBox1.Text.ToLower());
textBox1.Select(textBox1.Text.Length, 0);

Thanks again... :-)
