    I would not advise to use the above code, because for every adding and removing of an item programatically from the client-side, an automatic ASYNC postback is made, in order to syncronize the server-side collection as well. 

    What exactly is your use case? Why do you need to add (or remove, as it is shown above) items on the client, when the dropdown is opening? 

    Thanks,

    Angel
