textbox restricting spaces using c# code

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);

}

You can try like that(bind the event to textbox):

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if ((e.KeyChar >= 65 && e.KeyChar <= 91) || (e.KeyChar >= 97 && e.KeyChar <= 123))
{
if (i && e.KeyChar == 69)
{
i = false;
}
else if (e.KeyChar!=69)
{
e.Handled = true;
}
}
}
