repeater问题？？？————为什么会这样？？？

选项删除怎么能放在item事件中，你这种方法本身就矛盾，如果每行加入删除按钮，就没有必须每行加CheckBox判断，如果加入CheckBox，就做一个删除按钮放在外面。

我就是这样但在点击button的时候，没有任何的响应？？？？另外，贴错一个属性，抱歉<th> <ASP:Button Text="del" runat="server" ID="btnDelete" />
。
<asp:CheckBox ID="ckbID" CommandName="delete" runat="server"> </asp:CheckBox>应改为：
<th> <ASP:Button Text="del" CommandName="delete" runat="server" ID="btnDelete" />
。
<asp:CheckBox ID="ckbID" runat="server"> </asp:CheckBox>

给你一个完整的.xml文件删除和编辑的例子：

回复 xrll() ：
这种情况我在DATAGRID中实现过，但是在REPEATER对XML的操作我还不是很清楚。这样的好处是在外面没有多余的东西，同时可以一次删除多个数据。另外，我想向高手请教的是：在REPEATER中加入一个控件后一些绑定问题，请赐教！！！

在编译向该请求提供服务所需资源的过程中出现错误。请检查下列特定错误详细信息并适当地修改源代码。编译器错误信息: CS0122: 不可访问“viewguest.delete_Row(object, System.Web.UI.WebControls.RepeaterCommandEventArgs)”，因为它受保护级别限制源错误:
行 17：
<asp:repeater id="MyDataList" OnItemCommand ="delete_Row" runat="server">
这是在repeaterk中加入OnItemCommand ="delete_Row"后出现的编译错误，为什么会这样呢？？？？

将viewguest.delete_Row(object, System.Web.UI.WebControls.RepeaterCommandEventArgs)声明为public viewguest.delete_Row(object, System.Web.UI.WebControls.RepeaterCommandEventArgs)试试!

你看看这个REPEATER使用CHECKBOX的效果：
http://218.84.107.5/o.aspx

void onbt(Object Sender, EventArgs e) {
for( int i = 0; i < MyRepeater.Items.Count; i++ ){
      CheckBox chk = ( CheckBox )MyRepeater.Items[i].FindControl("chk1");
if( chk.Checked )
{
          int row = (int)MyRepeater.Items[i].ItemIndex;
        dv.Delete(row);
        fin = new FileStream(Server.MapPath("key.xml"),FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite);
    ds.WriteXml(fin, XmlWriteMode.WriteSchema);
    fin.Close();
        BindRepeater();
  }
    }
           BindRepeater();
}
