GridView 72般绝技(申精).docVIP

C#精髓 GridView 72般绝技 1.GridView无代码分页排序： 1.AllowSorting设为True，aspx代码中是AllowSorting=True； 2.默认1页10条，如果要修改每页条数，修改PageSize即可，在aspx代码中是PageSize=12。 3.默认的是单向排序的，右击GridView弹出“属性”，选择AllowSorting为True即可。 2.GridView选中，编辑，取消，删除： 效果图： 后台代码： 你可以使用sqlhelper,本文没用。代码如下： using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { //清清月儿/21aspnet SqlConnection sqlcon; SqlCommand sqlcom; string strCon = Data Source=(local);Database=数据库名;Uid=帐号;Pwd=密码; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { bind(); } } protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { GridView1.EditIndex = e.NewEditIndex; bind(); } //删除 protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) { string sqlstr = delete from 表 where id= + GridView1.DataKeys[e.RowIndex].Value.ToString() + ; sqlcon = new SqlConnection(strCon); sqlcom = new SqlCommand(sqlstr,sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); bind(); } //更新 protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { sqlcon = new SqlConnection(strCon); string sqlstr = update 表 set 字段1= + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + ,字段2= + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + ,字段3= + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + where id= + GridView1.DataKeys[e.RowIndex].Value.ToString() + ; sqlcom=new SqlCommand(sqlstr,sqlcon
