    I have an user control in an aspx page. I had find a sample that can be use as autocomplete function at listbox.
    In user control i had 3 search textboxes, and 3 listboxes. And the javascript code as follows:
    <script type="text/javascript">
        function filterListBox(sender, e) {
            var list = $find("<%= RadListBox1.ClientID %>");
            var searchText = sender.get_value() + e.get_keyCharacter();
            var items = list.get_items();
            for (var i = 0; i < items.get_count(); i++) {
                var item = items.getItem(i);
                if (item.get_text().toLowerCase().startsWith(searchText.toLowerCase())) {
    I don't want to write 2 more same javascript code block. And i decide to send the controls names to the javascript too. But as i see the sender and e arguments generating by telerik. And i can't add more arguments.
    How can i add two more arguments into this javascript?

    Hi Alperozgur,

    You cannot send more arguments to the function, but you have the textbox which fires the event, so you can find which listbox to update according to it.
