Solution 1

You need to use RegularExpressionValidator for this purpose.See this solution:

Solution 3

you may use this...

C#

void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
     if ((sender as TextBox).SelectionStart == 0)
          e.Handled = (e.KeyChar == (char)Keys.Space);
     else
          e.Handled = false;
}
