设置AJAX Slider绑定控件号格式

Question

我有一个AJAX Slider Extender，它有一个有界控件，asp文本框工作正常，拖动滑块时值会发生变化。现在我的问题是，有没有办法在滑动时操纵限制为滑块的texbox的内容。例如，我的滑块设置为最小值1，最大值100现在我希望从1到9在有界文本框中显示为01,02,03 ...依此类推。下面是滑块控件的片段代码。

<tr>
                    <td class="label">
                        Call Start:
                    </td>
                    <td>
                        <asp:ImageButton ID="CallStart" ImageUrl="~/images/Icons/32/telephone.png" runat="server"
                            OnClientClick="show(); return false;" />
                        <asp:TextBox ID="tbxCallStart" runat="server" Enabled="false" BackColor="White" />
                        <div id="pnlCallStart" style="display: none;">
                            <table>
                                <tr>
                                    <td>
                                        <asp:TextBox ID="txtCallStartHours" runat="server" Width="20px" Enabled="false" BackColor="White"
