ASP.NET中Gridview读取数据表列表页面常用操作-序号,编辑,删除,删除确认
ASP.NET中Gridview读取数据表列表页面常用操作-序号,编辑,删除,删除确认
前台ASPX代码 :
实现功能：自动增加的序号列,编辑删除按钮
GridView1_RowDataBound事件：初始化时候新增删除按钮时候的删除确认对话框,详见CS代码.
GridView1_RowCommand事件：点击列表中的编辑和删除按钮后的事件操作,详见CS代码.
关键设置0.设置好GridView1序号列:Text='<%# this.GridView1.PageIndex * this.GridView1.PageSize + this.GridView1.Rows.Count + 1%>
关键设置1.设置好GridView1的DataKeyNames属性为商业逻辑层的数据表中的主键
关键设置2.设置好GridView1的CommandName属性为"Edit"编辑或者"Delete"删除
关键设置3.设置好GridView1的CommandArgument='<%# DataBinder.Eval(Container,"RowIndex") %>'(获取行号)或者
CommandArgument='<%# Eval("ID") %>' (ID为数据表主键)
