Default Validation of TextBox Input

I need to validate the input to TextBox. Values allowed are either 0.00 or bteween 0-9. I wrote follwing function:
private bool isNumeric(string val)
{
    foreach (char c in val.ToCharArray())
      {
    if (!Char.IsDigit(c))
    {
    return false; }
      }
    return true;
}

but this does not accept 0.00 as numeric value or it does not accept . as numeric value. What is the best solution? I am not well versed with JavaScript.

Tank you

May I suggest using an ASP.NET Range Validator?

Here is an example:

<asp:RangeValidator Type=Double MinimumValue=0.0 MaximumValue=9.0 ControlToValidate="CONTROL ID" Runat=server />
