    Hi all,

    Can anyone tell me why the following javascript is not working?

            document.body.onload = function() {

                var txtDOB = document.getElementById("<%= txtDOB.ClientID %>");
                txtDOB.set_maxDate(new Date('2009/04/15'));

            }

    The error I get is "Object doesn't support the property or method" on the set_maxDate line.


    My aspx markup is

                        <telerik:RadDateInput ID="txtDOB" runat="server" DateFormat="dd/MM/yyyy">
                        </telerik:RadDateInput>

    I am using Telerik Q2 2009 (2009.2.826.35)

    Thanks
  2.

    Hello Andrew,

    In order to access the client object you should use the $find shortcut method:
    ASP.NET AJAX > Client Reference > Global Namespace > $find ...
    function pageLoad()
    {
       var txtDOB = $find("<%= txtDOB.ClientID %>");
       txtDOB.set_maxDate(new Date('2009/04/15'));
    }

    Kind regards,

    FYI I have also tried this in my markup

    <ClientEvents OnFocus="SetMaxDate()" />

    and then placed above code in a SetMaxDate() function but still txtDOB is null

    Hello Andrew,

    I updated my code-snippet to use the findControl (part of our static client-side library) method. Also you can find below a modified version of the "OnFocus" approach:
    Telerik static client library

    OnFocus approach:
    <script type="text/javascript">
        function SetMaxDate(sender, args)
        {
            sender.set_maxDate(new Date('2009/04/15'));
        }
    </script>
     
     
    <telerik:RadDateInput ID="txtDOB" runat="server" DateFormat="dd/MM/yyyy">
        <ClientEvents OnFocus="SetMaxDate" />
    </telerik:RadDateInput>

    pageLoad approach:
    <script type="text/javascript">
       function pageLoad()
       {
          var txtDOB = $telerik.findControl(document, "txtDOB");
          txtDOB.set_maxDate(new Date('2009/04/15'));
       }
    </script>

    I hope this helps.
