RadNumericTextBox Amount

[WebGeek]

I would like to show a message if someone inputs an Amount larger than my MaxValue.  For example, if they inputted $300 and my max value was $299, I would like to show them a link that says something like "Click here for help".  

Any suggestions?

Hello,

You can use the ValueChanging event for that purpose:

<script type="text/javascript">
    function valueChanging(sender, args)
    {
        if (args.get_newValue() > sender.get_maxValue())
            alert("Ooops.");
    }
</script>

<telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" MaxValue="299">
    <ClientEvents OnValueChanging="valueChanging" />
</telerik:RadNumericTextBox>

Thanks - based on what you sent me I was able to show/hide panels based on the following code:

<script type="text/javascript">
    function valueChanging(sender, args)
    {
        if (args.get_newValue() > sender.get_maxValue())
        {
            var problempnl = document.getElementById('<%=pnlProblem.ClientID%>');
            var contactinformationpnl = document.getElementById('<%=pnlContactInformation.ClientID%>');

            if (problempnl != null)
            {
                problempnl.style.visibility = "visible";
                contactinformationpnl.style.display = "none";
            }

        }

    }
</script>
