I need to access a RadComboBox that is defined in one .ascx file from a different .ascx file so that I can get/set values in it.  I've read this information https://docs.telerik.com/devtools/aspnet-ajax/general-information/get-client-side-reference#using-jquery-selectors but it isn't working.  All help is greatly appreciated.  Here are the details about what I have:

 

In View.ascx the control is specified:

<telerik:RadComboBox RenderMode="Lightweight" ID="cmbReportTool" filter="Contains" runat="server"
         oWrap="false" class="cmb-report-tool"  CheckBoxes="true" EnableCheckAllItemsCheckBox="true" width="400px">
</telerik:RadComboBox>

and the following JavaScript exists in a different .ascx file:

function () {

    var combo = $telerik.$("[id$='cmbReportTool']").get(0).control;

}

I've played around with the JS and used an alert() to quickly see what I have.  The following code presents "combo: [object HTMLDivElement]"

function () {
    var combo = $telerik.$("[id$='cmbReportTool']").get(0);

alert('combo: ' + combo);
}

 

The following code presents "combo: undefined"

function () {
    var combo = $telerik.$("[id$='cmbReportTool']").get(0).control;
alert('combo: ' + combo);
}

 

Here are some specifics about my environment:

OS: Windows 7 Enterprise with service pack 1
Browser: Internet Explorer 11
Telerik Web UI version 2016.3.1027.40

Hello Matthew,

Please find attached a video demonstrating how to inspect the rendered HTML by the control, how to obtain the ID and use it in order to get reference to the control regardless of whether it is accessed from an aspx/ascx or another page.
