DataList

DataList 可以一行读取数据源中的一行记录 而gridview,Repeater 一行就能读取数据源中的一行记录 DataListItem dli in DataList1.Items 得到所有控件的项 CheckBox cb = e.Item.FindControl("CheckBox1") as CheckBox; 触发command事件时，e.Item为该行的实例 string s= cb.Text; CommandArgument='<%# Eval("id") %>' 绑定字段 protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e) { if (e.CommandName == "del") { CheckBox cb = e.Item.FindControl("CheckBox1") as CheckBox; string s= cb.Text; showmessagebox(s); } } protected void Button1_Click1(object sender, EventArgs e) { foreach (DataListItem dli in DataList1.Items) { CheckBox cb = dli.FindControl("CheckBox1") as CheckBox; if (cb != null) { if (cb.Checked) { File.Delete(MapPath(@"img/" + cb.Text)); } } } setbind(); }
