Combobox doesnt fire OnClientItemsRequested

[Roberto]

I have an application in VS2008, I control the code with Team foundation, I I had to change my equipment and after installing all the components and software necessary and to again put the code in the new computer, the code no longer works of the same form.
the event OnClientItemsRequested= " UpdateItemCountField " no longer goes off. I have put alert and not even that sends, that is to say, it does not happen that way.

<telerik:RadComboBox ID="rcmdProgra" runat="server" Height="120px" Width="250px"
                                                        EmptyMessage="Programas" DataTextField="Nombre" DataValueField="Clave"
                                                        DropDownWidth="370px" EnableLoadOnDemand="true" EnableEmbeddedScripts="true"
                                                        Font-Size="XX-Small"
                                                        OnClientKeyPressing="ChangeValueRCB"
                                                        OnClientItemsRequested="UpdateItemCountField"
                                                        OnClientSelectedIndexChanged="selectedProgram"
                                                        OnItemsRequested="rcmbProgra_ItemsRequested">

it is possible to mention that in the other equipment, which does not install I, he himself code worked correctly; single it changes to me of equipment, needs to me to install something. 

I hope can help me please. thank you very much.

Hello Roberto,

We are not exactly sure what is causing the problem. See our test code which works as expected:

<script type="text/javascript">
       function ChangeValueRCB()
       { }

       function UpdateItemCountField() {
       alert(1)
        }

       function selectedProgram()
       { }

   </script>
   <div>
       <telerik:RadComboBox ID="rcmdProgra" runat="server" Height="120px" Width="250px"
           EmptyMessage="Programas"
           DataTextField="Text"
           DataValueField="Value"
           DropDownWidth="370px"
           EnableLoadOnDemand="true"
           EnableEmbeddedScripts="true"
           Font-Size="XX-Small"
           OnClientKeyPressing="ChangeValueRCB"
           OnClientItemsRequested="UpdateItemCountField"
           OnClientSelectedIndexChanged="selectedProgram"
           OnItemsRequested="rcmbProgra_ItemsRequested">
     </telerik:RadComboBox>

Does it work at your side?
