            Click on this ListBox and start typing to search for an entry:

            <br />
        <p>

            It works for a DropDownList too:

            The ListSearchExtender lets you search for items in a ListBox or DropDownList
            by typing.&nbsp; The extender performs an incremental search within the ListBox
            based on what has been typed so far.&nbsp; The prompt message that gets displayed
            when you click the list can be customized along with its CSS class and position.</p>

            The controls above are initialized with code like this.&nbsp; The <em>italic</em>
            properties are optional:</p>
        <pre>&lt;ajaxToolkit:ListSearchExtender id="LSE" runat="server"
    TargetControlID="ListBox1"
<em>    PromptText="Type to search"</em>
<em>    PromptCssClass="ListSearchExtenderPrompt"
    PromptPosition="Top"</em> /&gt; <em>
</em></pre>
        <ul>
            <li><strong>PromptText</strong> - Message to display when the ListBox or DropDownList
                is given focus.&nbsp; Default is 'Type to search'.&nbsp; The PromptText is replaced
                by the search text typed by the user.</li>
            <li><strong>PromptCssClass</strong> - The name of the CSS class to apply to the prompt
                message.&nbsp;</li>
            <li><strong>PromptPosition</strong> - Indicates whether the message should appear at
                the Top or Bottom of the ListBox.&nbsp; The default
                is Top. </li>
            <li><strong>Animations</strong> - Generic animations for the ListSearch extender.  See the
                <a href="../Walkthrough/UsingAnimations.aspx">Using Animations</a> walkthrough and
                <a href="../Walkthrough/AnimationReference.aspx">Animation Reference</a> for more details.
                <ul>
                    <li><strong>OnShow</strong> - The OnShow animation will be played each time the extender's
                        prompt is displayed.  The prompt will be positioned correctly but hidden.
                        The animation can use <span class="codeReference">&lt;HideAction Visible="true" /&gt;</span>
                        to display the prompt along with any other visual effects.</li>
                    <li><strong>OnHide</strong> - The OnHide animation will be played each time the extender's
                        prompt is hidden.</li>
                </ul>

            In Safari the ListSearchExtender only works with ListBoxes, not DropDownLists.

            In Opera the backspace key moves back a page in the browser history by default when
            it is pressed on a ListBox or DropDownList.&nbsp; To change this behavior you can
            go to Tools|Preferences|Shortcuts, edit the Keyboard setup, search for 揵ack
