Hi Robert,
One Suggestion is that you can programmatically find a range for RadNumericTextBox and assign those values in HiddenField, then compare those values with the RadNumericTextBox value in
OnValueChanged event. Please have a look into the sample code snippet which works fine at my end.
ASPX:
<telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" ClientEvents- OnValueChanged="OnValueChanged">
</telerik:RadNumericTextBox>
<asp:HiddenField ID="MinValue" runat="server" />
<asp:HiddenField ID="MaxValue" runat="server" />
JavaScript:
<script type="text/javascript">
function OnValueChanged(sender, args) {
//programatically set a maximum value and minimum value to the hidden fields
var max = document.getElementById("MaxValue").value;
var min = document.getElementById("MinValue").value;
if (args.get_newValue() < min && args.get_newValue() > max)
sender.set_value("");
}
</script>
Let me know if you have any concern.
Thanks,
Princy.
