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"
onclick="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();
}
