CausesValidation Property Does Not Trigger Validate Event

[Guest]

I have simple app with a textBox, a button and errorProvider. I have all the
controls CausesValidation set to true, and the following code:

private void textBox1_Validation(object sender, CancelEventArgs e)
{
string error = null;
if( textBox1.Text.Length == 0 )
{
error = "Please enter a name";
e.Cancel = true;
}
errorProvider1.SetError((Control)sender, error);
}

This event fails to fire even though I tab over to another control without
putting anything in the textbox. I've researched the internet and have come
up empty. Does anyone know whether there is something that I am failing to
do. Thanks

Have you verified that there is no space character in the TextBoc control? Do
you have the form's AutoValidate property set properly?

Good luck with your project,
