Javascript error for autocomplete functionality of RadComboBox

[Manishkumar]

HI,

I have to implement Autocomplete functionality on RadComboBox, functionality is working fine. But on page load, I am facing Javascript error. Like ‘Telerik.Webcontrols.RadComboBox’ is null or not an object.

I am currently using IE7 with VS2008. And Version 2010.3.1317.35 of Telerik.Web.UI.dll file.

 

RadComboBox Declaration:
<RadCmbBox:RadComboBox HighlightTemplatedItems="true" ID="radComboSelectBaseModule"

Skin="WindowsXP_IT" Height="100px" Width="200px" runat="server" SkinsPath="~/RadControls/Combobox/Skins"

AllowCustomText="true" MarkFirstMatch="true" AutoPostBack="true" Enabled="true"

Visible="true" TabIndex="1" OnSelectedIndexChanged="radComboSelectBaseModule_SelectedIndexChanged"

enableitemcaching="True" enableloadondemand="True" onitemsrequested="radComboSelectBaseModule_ItemsRequested" >

 Javascript added for functionality:

<script type="text/javascript">

   

    var prototype = Telerik.WebControls.RadComboBox.prototype;

    var set_text = prototype.set_text;

    var propertyChange = prototype._onInputPropertyChange;

 

    prototype.set_text = function (value) {

        this._skipEvent = 0;

        set_text.call(this, value);

    };

 

    prototype._onInputPropertyChange = function () {

        if (!event.propertyName)

            event = event.rawEvent;

        if (event.propertyName == "value") {

            this._skipEvent++;

            if (this._skipEvent == 2)

                return;

            propertyChange.call(this);

        }

    };

    </script>

Please suggest if there is any other way to complete this functionality with version 2010.3.1317.35.

Thanks.

Hi Manishkumar,

Could you clarify about the version of the controls that you use - is it for asp.net ajax or classic asp.net. In addition, if you use the ajax , you should access the prototype of the ComboBox in the following manner:

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

Kind regards,
