Is this what you are reffering to?

Also note, it renders lots of individual controls which is why your approach above will not work. If that is what you are using please read its documentation.

do you want to return the value from C# or javascript

The checkbox items mainly rendered as checkbox type input element and labels for it would be next to it. I have added one solution for it please have a look. You can just refer it as per your need.

1 solution

I have crested one test application for your scenario and its working great, please have a look into the below example :-

Controls in my page :
i) A 'asp:DropDownCheckBoxes' control

Ex :-

<asp:dropdowncheckboxes id="ddllanguage" xmlns:asp="#unknown">
        <style selectboxwidth="200" dropdownboxboxwidth="200" dropdownboxboxheight="130" />
        <texts selectboxcaption="Select Values" />
            <asp:listitem text="Test1" value="1"></asp:listitem>
            <asp:listitem text="Test2" value="2"></asp:listitem>
            <asp:listitem text="Test3" value="3"></asp:listitem>
            <asp:listitem text="Test4" value="4"></asp:listitem>

ii) A textbox to display the selected values
Ex :-
<asp:textbox runat="server" id="txtValue" clientidmode="Static" xmlns:asp="#unknown"></asp:textbox>

Now the jQuery code to populate the selected checkbox texts into the textbox as comma separated values :-

function onSelectionChange() {
            var selectedVals = '';
            $.each($('#ddllanguage input[type=checkbox]:checked'), function () {
                selectedVals += $("label[for='" + + "']").html() + ",";

NOTE : For getting selected values simply you can concat the 'this.value' to textbox rather than using the above snippet '$("label[for='" + + "']").html()'

The jQuery version used for the example is 1.7.1, you can use accordingly.

Hope this will definitely give you hint how to proceed.

It doesn't work if Select All option is selected.
