实现表情插入的问题

Question

问题是：
有80张图片作为表情，图片分别为1.gif~80.gif
目的是点下“显示图片”按钮，显示出表情图片的列表（这个列表我写在了一个PANEL中），并且每点击一个表情，在下面的TEXTBOX中显示出[表情代号]，如点击1.gif则在textbox中显示[1]。
为了点击一个图片不刷新网页，所以将所有表情和“显示图片”按钮写在了UPDATEPANEL中。代码如下
                   <asp:UpdatePanel ID="UpdatePanel1" runat="server" >
                    <ContentTemplate>
                         <asp:ImageButton ID="Imgbtn" runat="server" ImageUrl="/image/显示图片.jpg" onclick="Show"/>
                    <asp:Panel ID="pData" runat="server" BackColor=Black>
                        
                        <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="image/face/1.gif" OnClick="Face1"/>
                        <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="image/face/2.gif"/>
                        <asp:ImageButton ID="ImageButton3" runat="server" ImageUrl="image/face/3.gif"/>
                        <asp:ImageButton ID="ImageButton4" runat="server" ImageUrl="image/face/4.gif"/>
                        ........
                        </asp:Panel>
                    </ContentTemplate>
                    </asp:UpdatePanel>
Face1的代码是
protected void Face1(object sender, EventArgs e)
    {
        TextBox2.Text = TextBox2.Text + "[1]";
    }
但是我点击图片1的时候TEXTBOX2中没有任何变化，是否与UPDATEPANEL有关？
另外请达人帮忙简化代码这样枚举实在太麻烦了，不胜感激

Answer 1

对了，还有就是能不能在TEXTBOX的光标处插入代码，而不是TextBox2.Text = TextBox2.Text + "[1]"; 这样在最后插入

Answer 2

这个还要用 UPDATEPANEL？
楼主过于依赖这些控件了，这个用javascript完全能实现。

读取数据   protected void rpComment_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType != ListItemType.Header && e.Item.ItemType != ListItemType.Footer)
        { 
  Literal ltContetn = e.Item.FindControl("ltContent") as Literal;
            HiddenField HFcontent = e.Item.FindControl("HFcontent") as HiddenField;

            for (int i = 0; i < face.Length; i++)
            {
                content = content.Replace(face[i], "<img src='" + faceImg[i] + "' border='0'/>&nbsp;");
            }
            ltContetn.Text += content.ToString();
}
