如何获取Repeater以绑定的字段的某一行的值？

<asp:Repeater ID="rp1" runat="server" onitemdatabound="rp1_ItemDataBound">
<ItemTemplate>
<tr onmouseover="this.style.backgroundColor='#eafcd5'" onmouseout="this.style.backgroundColor='#ffffff'" bgcolor="#ffffff">
<td height="22" ><div align="center" class="STYLE1"><%#Eval("YongHuMing")%></div></td>
<td><div align="center" class="STYLE1"><%# Eval("QuanXian")%></div></td>
<td><div align="center" class="STYLE1"><%# Eval("WenTi")%></div></td>
<td><div align="center" class="STYLE1"><asp:LinkButton ID="LinkButton1" runat="server" OnClientClick="return confirm('确认要删除此行信息吗？')" OnClick="LinkButton1_Click">删除</asp:LinkButton></div></td>
</tr>
</ItemTemplate>
</asp:Repeater>
数据是以表格的形式显示在页面上的。
我想在LinkButton1_Click事件中实现某一行的删除，要获取这一行的YongHuMing字段的值，请问在后台怎么实现？

                    </asp:Repeater>
                </table>

    protected void rptLink_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        if (e.CommandName == "Delete")
        {
            if (lkBLL.Delete(e.CommandArgument.ToString()))
            {
                MessageBox.Show(this.Page, "删除成功！");
                BindData();
            }
            else
            {
                MessageBox.Show(this.Page, "删除失败！");
                return;
            }
        }
    }

注意要绑定事件: OnItemCommand="rptLink_ItemCommand"

前台绑定CommArgs在后台的Comm事件中获取e.CommArgs

追问

大神能不能详细点，前台绑定CommArgs怎么做，后台又怎么做？我没做过，是在不知道……

追答

CommandArgument=''前台在你的LinkButton上面绑定下这个,如果有2个LinkButton还需要绑定CommandName,方便识别是那个按钮点击
后台:
protected void btn_Cancel(object sender, CommandEventArgs e)绑定事件
获取e.CommandArgument,这个就是获取你绑定的值
