Answer 1

should be look like

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="TextBox1"
        ValidationExpression="^[A-Za-z ]+$" runat="server" ErrorMessage="RegularExpressionValidator"></asp:RegularExpressionValidator>
^[A-Za-z ]+$

As if you will see in the expression , there is space after small z, and this would allow space
