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:
