Hi all,

I am having the problem with the radCombobox where the ItemsRequested server side function is not firing after I type in more than a few letters. I am trying to apply the fix by adding the fix from this post.

However, when I place the code in and run, I am getting the error "Microsoft JScript runtime error: 'Telerik' is undefined"

The declarations at the top of my page look like this:

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">

Telerik.Web.UI.RadComboBox.prototype.get_endOfItems = function() { return false; };

</script>

Any suggestions on where I should enter this? I tried placing it as well in my master page after the declaration of the script manager, but I go tthe same result.

Thanks,

Joshua Wise

Hi,

Is there any way you can post a sample? Here's the code I have, but I'm still getting an error:

                    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>         
            <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>         
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

                    <style type="text/css">         
                        </style>         
                </asp:ContentPlaceHolder>         
            </head>         
            <body>         
                <form id="form1" runat="server">         
                <div>         
                    <h1 class="header1">         
                        &nbsp;

                        <asp:Label ID="Label1" runat="server">Chart of Accounts Utility</asp:Label>         
                        <asp:ScriptManager ID="ScriptManager1" runat="server">         
                        </asp:ScriptManager>         
                     
                        <script type="text/javascript">         
                            Telerik.Web.UI.RadComboBox.prototype.get_endOfItems = function() { return false; };          
                        </script>         
                     
                    </h1>         

The Error I'm getting is this:

Microsoft JScript runtime error: 'Telerik.Web.UI.RadComboBox.prototype' is null or not an object

Thanks

HI,
Thanks for this fix and i was able to get results after pressing more than one character. But this solution raised me another issue.

I Used Property ShowMoreResultsBox="true" in combo box because I have about 16000 reocords in Combo Box, and I display 500 records on a page. The Button to get next 500 records works fine till i dont type any character and when I press two or more characters the my webservice return 2000 records, and I display 500 but I am not able to get Next 500 records, becuase the button does not clickable ot just return false; (I guess becuase of this fix).
The issue is on production and We dont want to update with new Telerik dlls.
Please help me to fix this issue.

Thanks
Aviii

Hello Aviii,

You can try resolving this (without updating the dll) by replacing the fix suggested in the forum sticky with this one:

var requestItems = Telerik.Web.UI.RadComboBox.prototype.requestItems;

Telerik.Web.UI.RadComboBox.prototype.requestItems = function (text, appendItems) {

if (appendItems && this.get_endOfItems())

return;

this.set_endOfItems(false);

requestItems.apply(this, arguments);

};

Please let me know how it goes on your side after applying this fix.
