I must capitalize first letter of every word but with keypress event using C#. Right now every letter in the textbox gets capitalized, I added the code I use. I cant figure out how to capitalize just the first letter, or what am I doing wrong. Can you help me?
private void txt_name_KeyPress(object sender, KeyPressEventArgs e)
{
e.KeyChar = (e.KeyChar.ToString()).ToUpper().ToCharArray()[0];
}
I got by using Keydown
private void tbxName_KeyDown(object sender, KeyEventArgs e)
{
if (tbxName.Text.Length == 0 || tbxName.SelectedText.Length == tbxName.Text.Length)
{
if ((e.Key >= Key.A) && (e.Key <= Key.Z))
{
tbxName.Text = e.Key.ToString().ToUpper();
tbxName.SelectionStart = tbxName.Text.Length;
e.Handled = true;
}
}
if (tbxName.Text.Length > 0)
{
int selectionStart = tbxName.SelectionStart;
string character = tbxName.Text.Substring(selectionStart - 1, 1);
if (character.Trim() == string.Empty)
{
if ((e.Key >= Key.A) && (e.Key <= Key.Z))
{
tbxName.Text = tbxName.Text.Insert(selectionStart, e.Key.ToString().ToUpper());
tbxName.SelectionStart = selectionStart + 1;
e.Handled = true;
}
}
}
if (e.Key == Key.Enter || e.Key == Key.Tab)
{
if (tbxName.Text.Length > 2)
{
tbxDegree.Focus();
if (e.Key == Key.Tab)
e.Handled = true;
}
else
{
MessageBox.Show("Kindly verify the Name Entered");
tbxName.Focus();
}
}
}
You will need to keep track of previous key presses if you must go this route:
private char PreviousChar;
private void txt_name_KeyPress(object sender, KeyPressEventArgs e)
{
if (Char.IsWhiteSpace(PreviousChar) || PreviousChar == '\0')
{
e.KeyChar = Char.ToUpper(e.KeyChar);
}
PreviousChar = e.KeyChar;
}
