I have a website that uses the AjaxControlToolkit. I’m making some parallel iPhone-friendly pages for the site, and since Ajax isn’t very good-looking in a mobile browser, I’m trying to phase it out. One such Ajax tool is the CalendarExtender, which I replaced with the iPhone’s Date Picker using this method.

The second tool I need to replace is the AutoCompleteExtender. It functions as a simple dropdown menu when the user types text into a text box. The purpose is for searching functionality; I have a large list of contacts, and when the user starts to type in a name or company name the extender appears with a list of suggestions based on what the user typed in so far.

Here’s what it looks like in Ajax:

<asp:TextBox ID="NameTextBox" runat="server" AutoComplete="off" AutoPostBack="True"
                                        OnTextChanged="NameTextBox_TextChanged" Width="95%" Font-Size="Medium"></asp:TextBox>
                                    <cc1:AutoCompleteExtender ID="NameTextBox_AutoCompleteExtender" runat="server" CompletionInterval="250"
                                        CompletionListCssClass="autocomplete_completionListElement" CompletionListHighlightedItemCssClass="autocomplete_highlightedListItem"
                                        CompletionListItemCssClass="autocomplete_listItem" DelimiterCharacters="" Enabled="True"
                                        MinimumPrefixLength="2" ServiceMethod="GetCompletionList" ServicePath="" TargetControlID="NameTextBox"
                                        UseContextKey="True">
                                    </cc1:AutoCompleteExtender>

What is a good way to replace this with either a common piece of iPhone UI (such as the UIPickerView), or a more general mobile-friendly piece of HTML?

    I would use a standard HTML element to maintain user experience.
    For the autocomplete part I would use some javascript or an jQuery plugin. You could also choose to use Autocomplete from jQuery UI: http://jqueryui.com/demos/autocomplete/.
