Problems using changeGroupOperator

[Robin]

I found this page: http://www.telerik.com/help/aspnet-ajax/filter-getting-familiar-with-client-side-api.html 

I tried to replicate the sample regarding changeGroupOperator but it's not working. I see the 1st alert but never see the second alert. I had to use $get as $find kept returning null.

    <telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">
<script type="text/javascript" language="javascript">
    var tmp1 = $get("<%= rfPortfolios.ClientID %>");
    alert(tmp1);
    tmp1.changeGroupOperator("0", "Or");
    alert('123');
</script>
</telerik:RadCodeBlock>

This is my scriptmanager:

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server"
        LoadScriptsBeforeUI="false"
        EnableScriptGlobalization="true"
         EnableScriptLocalization="true"
         EnablePartialRendering="true"
         EnablePageMethods="true"
         ScriptMode="release" >
                 <Scripts >
            <ajax:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js">
            </ajax:ScriptReference>
            <ajax:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js">
            </ajax:ScriptReference>
            <ajax:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js">
            </ajax:ScriptReference>
        </Scripts>
</telerik:RadScriptManager>

Any ideas what's going wrong?

Thanks.

Hello Robin,

Note that the sample code in this page uses $find, not $get to access the RadFilter control. $get returns only its DOM representation but not the actual client object. So, try with:

<telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">
    <script type="text/javascript" language="javascript">
       var tmp1 = $find("<%= rfPortfolios.ClientID %>");
       alert(tmp1);
       tmp1.changeGroupOperator("0", "Or");
       alert('123');
    </script>
</telerik:RadCodeBlock>

More information on the difference between $find and $get is available here:

Thank you for responding to my question, you did not address my problem. I stated that I was having issues with $find.
"I tried to replicate the sample regarding changeGroupOperator but it's not working. I see the 1st alert but never see the second alert. I had to use $get as $find kept returning null."

Since tmp1 is null, changeGroupOperator fails and I never see the second alert. If I am supposed to use $find, then is there any way you can figure out why $find is not working?

Thank you.

Never mind, I figured out what was wrong. I needed to wrap my javascript inside a pageLoad.
