Not less than zero or zero

Answer 1

You can set up a CompareValidator with those conditions.
Add a RequiredFiedlValidator if you don't want it to be left empty.

The aspx looks like this:

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:CompareValidator ID="CompareValidator1" runat="server"
      ControlToValidate="TextBox1" ErrorMessage="Must be &gt; 0"
      Operator="GreaterThan" Type="Integer"
      ValueToCompare="0" />
