You are implementing an ASP.NET Web page. You need to add a text box that allows only values
between 1 and 10, inclusive, to be submitted. Which two code segments should you use? (Each
correct answer presents part of the solution. Choose two.)

A.
<script type=”text/javascript”>
function validate_value(obj, args) {
return
(args.Value >= 1 && args.Value <= 10);
}
</script>

B.
<script type=”text/javascript”>
function validate_value(obj, args) {
args.IsValid =
(args.Value >= 1 && args.Value <= 10);
}
</script>

C.
<asp:TextBox ID=”txt1″ runat=”server” />
<asp:CustomValidator ID=”val1″ runat=”server”
ControlToValidate=”txt1″
ClientValidationFunction=”validate_value”
ErrorMessage=”Value invalid” />

D.
<asp:TextBox ID=”txt1″ runat=”server” onChange=”validate_value(this, args)” />
