GridView無(wú)代碼分頁(yè)排序
GridView選中，編輯，取消，刪除
GridView正反雙向排序
GridView和下拉菜單DropDownList結(jié)合
GridView和CheckBox結(jié)合
鼠標(biāo)移到GridView某一行時(shí)改變?cè)撔械谋尘吧椒ㄒ?BR>鼠標(biāo)移到GridView某一行時(shí)改變?cè)撔械谋尘吧椒ǘ?BR>GridView實(shí)現(xiàn)刪除時(shí)彈出確認(rèn)對(duì)話(huà)框
GridView實(shí)現(xiàn)自動(dòng)編號(hào)
GridView實(shí)現(xiàn)自定義時(shí)間貨幣等字符串格式
GridView實(shí)現(xiàn)用“...”代替超長(zhǎng)字符串
GridView一般換行與強(qiáng)制換行
GridView顯示隱藏某一列
GridView彈出新頁(yè)面/彈出新窗口
GridView固定表頭(不用Javascript只用CSS，2行代碼，很好用)
GridView合并表頭多重表頭無(wú)錯(cuò)完美版（以合并3列3行舉例）
GridView突出顯示某一單元格（例如金額低于多少，分?jǐn)?shù)不及格等）
GridView加入自動(dòng)求和求平均值小計(jì)
GridView數(shù)據(jù)導(dǎo)入Excel/Excel數(shù)據(jù)讀入GridView

1.GridView無(wú)代碼分頁(yè)排序：

效果圖：

1.AllowSorting設(shè)為T(mén)rue，ASPx代碼中是AllowSorting="True"；
2.默認(rèn)1頁(yè)10條，如果要修改每頁(yè)條數(shù)，修改PageSize即可，在ASPx代碼中是PageSize="12"。
3.默認(rèn)的是單向排序的，右擊GridView彈出“屬性”，選擇AllowSorting為T(mén)rue即可。


2.GridView選中，編輯，取消，刪除：

效果圖：

后臺(tái)代碼：
你可以使用sqlhelper,本文沒(méi)用。代碼如下：

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
{

    {
        GridView1.EditIndex = e.NewEditIndex;
        bind();
    }

    {
        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();

        string sqlstr = "update 表 set 字段1='"
            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',字段2='"

        sqlcom=new SqlCommand(sqlstr,sqlcon);
        sqlcon.Open();
        sqlcom.ExecuteNonQuery();
        sqlcon.Close();
        GridView1.EditIndex = -1;
        bind();

//取消
    protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        GridView1.EditIndex = -1;

        string sqlstr = "select * from 表";
        sqlcon = new SqlConnection(strCon);
        SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
        DataSet myds = new DataSet();
        sqlcon.Open();
        myda.Fill(myds, "表");
        GridView1.DataSource = myds;
        GridView1.DataKeyNames = new string[] { "id" };//主鍵
        GridView1.DataBind();
        sqlcon.Close();
    }
}

3.GridView正反雙向排序：
效果圖：點(diǎn)姓名各2次的排序，點(diǎn)其他也一樣可以。
