Select all or Unselect all in listbox using jquery?

I have asp.net listbox. first item of the listbox is "--All--". If user selected 1st item of the list then automatically select all items. If user unselect 1st item of list then automatically unselect all items. How can I do that using jquery?

    <asp:ListBox ID="lstDatabases" runat="server" Height="134px" Width="396px" SelectionMode="Multiple" >
</asp:ListBox>

jQuery: Select all options in a Multiple Select Listbox

$("#multipleselect option").prop("selected",true);

A multiple select listbox with everything already selected for you!

You can try something like this:

$("#selectId").on('change', function() {
    if ($(this).val() == "all") {
        $("select > option").prop("selected", true);
    }
});
