Hi Dinusha I don't know if this would be of any help to you? It capitalizes the first letter in the sentence. here's the dll to reference then to use place this in your code behind private void textBox1_TextChanged( object sender TextChangedEventArgs e) { ControlInput controlInput = new ControlInput (); sender = controlInput.Capitalise(sender); } and this in your XAML TextBox TextChanged =textBox1_TextChanged />

This should work OK: private void txtCustName_KeyPress( object sender KeyPressEventArgs e) { e.KeyChar = Char .ToUpper(e.KeyChar); }

This line of code is working and should do the same :) e . KeyChar = ( e . KeyChar . ToString ()). ToUpper (). ToCharArray ()[ 0 ];

Hi This is the TextBox Validation Take a KeyPressEvent 1. Numeric Only e.Handled =!Char.IsDigit(e.KeyChar) && e.KeyChar != '\b'; 2. Character Only e.KeyChar = Char.ToUpper(e.KeyChar); // Char.ToLower(e.KeyChar); e.Handled = Char.IsDigit(e.keyChar) && e.KeyChar != '\b';

Thanks Alan..... So Ryan How do you do that? That is a property which you want to change in each control. Is it?

Ryan Alford · Answer

instead of converting it to an upper case letter why not just only allow upper case letters? all textboxes have a character casing property. set it to upper and you won't have to do any of this.
