Hi!

Can I force a RadDateInput to use the first month / the first day or the last month / the last day as auto-complete values instead of the month/day och today? E.g. I want to have two inputs where in the user can type "1980" in the first, and I always want that to auto-complete as 1980-01-01 no matter the date. In the second input the user can type "1984" and that should auto-complete as 1984-12-31.

Possible?

From this it also follows that if the user in the second input types "1984-02" the auto-complete should be 1984-02-29, and "1983-02" should be 1983-02-28.

Hi Christoffer,

The described behavior is not supported out-of-the-box, but can be implemented with a couple of Javascript functions. Here is a simple demo, which shows how to set January 1 or December 31 as day and month, if the user enters a year only. Use it as a starting point for any custom autocomplete behaviors that you may need.

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
 
<script runat="server">
 
</script>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 
<head id="Head1" runat="server">
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<title>RadControls</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
 
<telerik:RadDateInput ID="RadDateInput1" runat="server" Label="Start">
    <ClientEvents OnValueChanging="autoComplete1" />
</telerik:RadDateInput>
 
<br /><br />
 
<telerik:RadDateInput ID="RadDateInput2" runat="server" Label="End">
    <ClientEvents OnValueChanging="autoComplete2" />
</telerik:RadDateInput>
 
<script type="text/javascript">
 
function autoComplete1(sender, args)
{
    var tbValue = sender.get_textBoxValue();
    if (tbValue.length == 4)
    {
        args.set_cancel(true);
        var newDate = new Date(tbValue, 0, 1);
        window.setTimeout(function(){sender.set_selectedDate(newDate);}, 1);
    }
}
 
function autoComplete2(sender, args)
{
    var tbValue = sender.get_textBoxValue();
    if (tbValue.length == 4)
    {
        args.set_cancel(true);
        var newDate = new Date(tbValue, 11, 31);
        window.setTimeout(function(){sender.set_selectedDate(newDate);}, 1);
    }
}
 
</script>
 
</form>
</body>
</html>

Hi!

I'm using your exact example, but the RadDateInput does not get the new value of the newDate variable. It just gets no value at all and the Input warns me.

What's wrong?

Hi Christoffer,

The example works as expected on my side. Which RadControls version are you testing with?

Kind regards,

I'm using version 2010.2.826.35 and I'm running Visual Studio 2008. It doesn't update the textbox with a new value from the newDate variable. When I do an alert(newDate) I can see that the date value is correct, but the textbox doesn't get it.

Hi Christoffer,

I am afraid I can't see anything wrong with the provided example. Please send us a formal support ticket with a non-working example attached.
