Hello Mark,
Now I see. Well, we can consider implementing this for a future version of the control, based on customer feedback and task priorities. At present you can use the following approach:
<%@ Page Language="C#" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<head runat="server">
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<title>RadControls for ASP.NET AJAX</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<telerik:RadNumericTextBox ID="RadTextBox1" runat="server">
<NumberFormat DecimalDigits="3" />
<ClientEvents OnValueChanged="MyValueChanged" OnBlur="MyBlur" />
</telerik:RadNumericTextBox>
<script type="text/javascript">
function MyValueChanged(sender, args)
{
var v = args.get_newValue().toString();
ModifyValue(sender, v);
}
function MyBlur(sender, args)
{
var v = sender.get_value().toString();
ModifyValue(sender, v);
}
function ModifyValue(tb, v)
{
if (v.indexOf(".") != -1)
{
var parts = v.split(".");
if (parts[1].length < tb.get_numberFormat().DecimalDigits)
{
window.setTimeout(function(){tb._textBoxElement.value = v;}, 1);
}
}
}
</script>
</form>
</body>
</html>
Greetings,
