repeater 的另外一种用法，不一定需要在databound加载事件

<asp:Button ID="btnDel" Text="删除" CssClass="btnCommon" runat="server"      οnclick="btnDel_Click" OnClientClick="return confirm('是否真的要删除?');" />

 protected void btnDel_Click(object sender, EventArgs e) {  Asset_BrandTableLogic logic=new Asset_BrandTableLogic();  foreach (RepeaterItem item in DataView.Items)  {   if (item.ItemType == ListItemType.Item)   {    if (((CheckBox)item.FindControl("Check")).Checked)    {     int id = objTool.ConvertToInt(((Label)item.FindControl("BD_ID")).Text.Trim());     if (id > 0)      logic.DeleteByKey(null, id);    }   }  }  DataViewBind(); }
