You can try like that(bind the event to textbox): private void textBox1_KeyPress( object sender KeyPressEventArgs e) { if ((e.KeyChar >= 65 && e.KeyChar = 97 && e.KeyChar { if (i && e.KeyChar == 69) { i = false ; } else if (e.KeyChar!=69) { e.Handled = true ; } } }

Better to use the TextBox.TextChanged Event. private void myTextBox_TextChanged(object sender EventArgs e) { TextBox tb = sender as TextBox; if (tb != null) { YourButton.Enabled = !string.IsNullOrWhiteSpace(tb.Text); } }
