how do i use jQuery get the parent radcombobox control object from the checkbox click event?

Question

I have a radcombobox with checkboxes turned on. I wrote a jQuery script to add a click event to all of them. What I need to move on to the next step is a way to get the combobox in which that item/checkbox resides. Something like this:

$(."comboBoxTag.find(":checkbox").click(
        function(){
            var cboObject = $(this).???
        });

this way I can do things like access the telerik api methods like cboObject.get_items();

I have the control tagged with a CSS class called "AssigneeTag", but doing a .closest(".AssigneeTag") isn't returning anything...

any ideas?

UPDATE: As requested:

                        </rad:RadListView>

            </div>
        </ItemTemplate>
    </rad:RadListView>

This is a listview with another listview nested in the itemtemplate. in the itemtemplate of the inner list resides the controls. The combobox im referring to is named cboAssignTo. It is a Telerik combobox, so it does not work like a traditionial DropDown menu, which I think is what is really complicating this on top of the fact that the comboboxes are dynamically generated. I was able to do things like $(this).closest(".rcbTag") to get the values of the other combobox called cboStatus, but this other combobox involves a bit more as it has checkboxes.

EDIT:

Here is a watered down easier to read version of what stage I'm at. This is the HTML generated by a single instance of this combobox:

<div id="lsvTest" class="RadComboBox RadComboBox_Default RcbTag" style="width:160px;">
    <table summary="combobox" style="border-width:0;border-collapse:collapse;table-layout:fixed;width:100%">
        <tr class="rcbReadOnly">
            <td style="margin-top:-1px;margin-bottom:-1px;width:100%;" class="rcbInputCell rcbInputCellLeft">
                <input name="lsvTest" type="text" class="rcbInput" id="lsvTest_Input" value="" style="display: block;" readonly="readonly" />
            </td>
            <td style="margin-top:-1px;margin-bottom:-1px;" class="rcbArrowCell rcbArrowCellRight">
                <a id="lsvTest_Arrow" style="overflow: hidden;display: block;position: relative;outline: none;">select</a>
            </td>
        </tr>
    </table>

    <!-- 2012.1.215.40 -->
    <div class="rcbSlide" style="z-index:6000;">
        <div id="lsvTest_DropDown" class="RadComboBoxDropDown RadComboBoxDropDown_Default " style="float:left;display:none;">
            <div class="rcbScroll rcbWidth" style="width:100%;">
                <ul class="rcbList" style="list-style:none;margin:0;padding:0;zoom:1;">
                    <li class="rcbItem "><input type="checkbox" class="rcbCheckBox" />One</li>
                    <li class="rcbItem "><input type="checkbox" class="rcbCheckBox" />Two</li>
                    <li class="rcbItem "><input type="checkbox" class="rcbCheckBox" />Three</li>
                </ul>
            </div>
        </div>
    </div>
    <input id="lsvTest_ClientState" name="lsvTest_ClientState" type="hidden" />
</div>

Just looking at this, I feel like clicking a checkbox and then using $(this).closest(".RcbTag") should traverse all the way to the top and grab the outer div, but it is not.

我使用jQuery parent（）调用解决了类似的问题，您尝试过吗？

As with the other question, I think your life will be easier if you stick with the Telerik-sanctioned methods. Here is how you could do it using them:

<script language="javascript" type="text/javascript">
    function OnClientItemChecked(sender, eventArgs) {
        var item = eventArgs.get_item();
        var combo = item.get_comboBox(); // Now you have a reference to the parent ComboBox
    }
</script>

And the RadComboBox itself:

<telerik:RadComboBox ID="RadComboBox1" runat="server" 
    OnClientItemChecked="OnClientItemChecked" CheckBoxes="true">
</telerik:RadComboBox>
