TextBox Validation

How make validatin that whitespace are not allowed in textbox? How i get the key code of press key?

There are two different things you can do: 1. Handle Validating event for the TextBox, and use regular expressions to validate that no spaces are in the string the user entered, and if yes, don't allow the user to go to another control before correcting it. 2. In the KeyDown event, if the key is a space, set e.Handled = true, so the TextBox doesn't handle it, effectively eating the keystroke. -- LuisR

i tried using this but it does not work i tried using this sample code. private void textBox1_KeyDown(object sender,System.Windows.Forms.KeyEventArgs e) { if(e.KeyValue==65) { e.Handled=true; } } it still prints the character 'a' in the text box
