    I have a combobox with the following:
        AllowCustomText = False
        Filter = Contains
        IsCaseSensitive = False
        MarkFirstMatch = True
        OpenDropDownOnLoad = True

    When I type something into the text area, the list of items shrinks to what matches what I've typed in so far.  I can then select from a smaller list the item I want.  This all works fine.

    My problem is that I need to somehow erase what I typed in but not what I selected.  I need to do this so that when I click on the drop-down again, all items are shown and not only the ones that had what I typed in them.

    I cannot seem to find cbox.filterExpression or cbox.currentFilterValue to reset to "".

    I am using version 2010.3.1317.35.

    Any help would be very appreciated!!!

    Hello Susan,

    In order to achieve the desired behavior you could subscribe on the client-side OnClientDropDownOpening event and use the following implementation of the event handler function:
    function OnClientDropDownOpening(sender, args) {
               $telerik.$("li", sender.get_dropDownElement()).each(function () {
                   if ($telerik.$(this).css("display") == "none") {
                       $telerik.$(this).css("display", "");

    All the best,
