在girdview中加入

<asp:Button ID="btnDelete" runat="server" CausesValidation="false" Text="删除" CommandName="Delete"
                            CommandArgument='<%# DataBinder.Eval(Container.DataItem, "ID").ToString()%>'
                            OnClientClick="return closeme()" />

之后在后台的uxGrid_RowCommand事件中

protected void uxGrid_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName != "Page")
            {
                 if (e.CommandName == "Delete")
                {
                    //需要删除的操作

                    ScriptHelper.MsgBox(this.Page, "删除成功！");
                    this.BindGridData(ID);
                }
            }
        }

就是这么简单

首先获取GridView你要删除行的索引 有了索引，你就只需要写SQL语句了 http://blog.csdn.net/yangmingxing980/article/details/22091741

[小蜗牛1]

protected void lbtn_UnconfirmedQuotes_delete(object sender, GridViewDeleteEventArgs e) { ////获得此条数据的id string id= GridView_UnconfirmedQuotes.Rows[e.RowIndex].Cells[0].Text; string sqlstr="delete from table1 where id="+id; CommonMySql.MySql_Delete(sqlstr); } 前台加入onrowdeleting="lbtn_UnconfirmedQuotes_delete"绑定事件，后台编写处理函数，获得id，然后删除。

Rows[i].Cells[j].Text获取gridvew中的记录ID，然后就可以删除了

楼上太坑了，一个删除而已，20行搞定

点按钮删除gridview选中行。
