1.GridView简单代码分页排序：
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。
4.添加代码:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
Bind();
}
2.GridView选中，编辑，取消，删除：
后台代码：
using System;

public partial class _Default : System.Web.UI.Page
{

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);

+ ((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);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
GridView1.EditIndex = -1;
bind();
}
//取消

GridView1.DataKeyNames = new string[] { "id" };//主键
GridView1.DataBind();
sqlcon.Close();
}
}

</asp:GridView>
3.GridView正反双向排序：
后台代码：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Data.SqlClient;
public partial class Default3 : System.Web.UI.Page
{ SqlConnection sqlcon;
string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ViewState["SortOrder"] = "身份证号码";
ViewState["OrderDire"] = "ASC";
bind();
}
}
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
string sPage = e.SortExpression;
if (ViewState["SortOrder"].ToString() == sPage)
{
if (ViewState["OrderDire"].ToString() == "Desc")
ViewState["OrderDire"] = "ASC";
else
ViewState["OrderDire"] = "Desc";
}
else
{
ViewState["SortOrder"] = e.SortExpression;
}
bind();
}
public void bind()
{
string sqlstr = "select top 5 * from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飞狐工作室");
DataView view = myds.Tables["飞狐工作室"].DefaultView;
string sort = (string)ViewState["SortOrder"] + " " + (string)ViewState["OrderDire"];
view.Sort = sort;
GridView1.DataSource = view;
GridView1.DataBind();
sqlcon.Close();
}
}

4.GridView和下拉菜单DropDownList结合：
后台代码：

using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飞狐工作室");
GridView1.DataSource = myds;
GridView1.DataBind();
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
DataRowView mydrv = myds.Tables["飞狐工作室"].DefaultView[i];
if (Convert.ToString(mydrv["员工性别"]).Trim() == "True")
{
ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");
ddl.SelectedIndex = 0;
}
if (Convert.ToString(mydrv["员工性别"]).Trim() == "False")
{
ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");
ddl.SelectedIndex = 1;
}
}
sqlcon.Close();
}
}
public SqlDataReader ddlbind()
{
string sqlstr = "select distinct 员工性别 from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlCommand sqlcom = new SqlCommand(sqlstr, sqlcon);
sqlcon.Open();
return sqlcom.ExecuteReader();
}
前台主要代码：

5.GridView和CheckBox结合：
后台代码：
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 Default5 : System.Web.UI.Page
{
SqlConnection sqlcon;
string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();
}
}
protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (CheckBox2.Checked == true)
{
cbox.Checked = true;
}
else
{
cbox.Checked = false;
}
}
}
protected void Button2_Click(object sender, EventArgs e)
{
sqlcon = new SqlConnection(strCon);
SqlCommand sqlcom;
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (cbox.Checked == true)
{
string sqlstr = "delete from 飞狐工作室 where 身份证号码='" + GridView1.DataKeys[i].Value + "'";
sqlcom = new SqlCommand(sqlstr, sqlcon);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
}
}
bind();
}
protected void Button1_Click(object sender, EventArgs e)
{
CheckBox2.Checked = false;
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
cbox.Checked = false;
}
}
public void bind()
{
string sqlstr = "select top 5 * from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "tb_Member");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "身份证号码" };
GridView1.DataBind();
sqlcon.Close();
}
}
前台主要代码：
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False"
CellPadding="3" Font-Size="9pt" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px">
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="身份证号码" HeaderText="用户ID" SortExpression="身份证号码" />

<asp:Button ID="Button2" runat="server" Font-Size="9pt" Text="删除" OnClick="Button2_Click" />
6.鼠标移到GridView某一行时改变该行的背景色方法一：
做法：
双击GridView的OnRowDataBound事件；
在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//首先判断是否是数据行
if (e.Row.RowType == DataControlRowType.DataRow)
{
//当鼠标停留时更改背景色
e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");
//当鼠标移开时还原背景色
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
}
}
前台代码：
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>实现鼠标划过改变GridView的行背景色清清月儿http://blog.csdn.net/21aspnet </title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"
DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="身份证号码" ReadOnly="True" SortExpression="身份证号码" />
<asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" SortExpression="家庭住址" />
<asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
</Columns>
<FooterStyle BackColor="White" ForeColor="#000066" />
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"
SelectCommand="SELECT top 5 [身份证号码], [姓名], [员工性别], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>
</div>
</form>
</body>
</html>
7.鼠标移到GridView某一行时改变该行的背景色方法二：
做法：和上面的一样就是代码不同
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//如果是绑定数据行
if (e.Row.RowType == DataControlRowType.DataRow)
{
//鼠标经过时，行背景色变
e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
//鼠标移出时，行背景色变
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
}
}
8.GridView实现删除时弹出确认对话框：
实现方法：
双击GridView的OnRowDataBound事件；
在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//如果是绑定数据行
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
{
((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：/"" + e.Row.Cells[1].Text + "/"吗?')");
}
}
}
9.GridView实现自动编号：
实现方法：
双击GridView的OnRowDataBound事件；
在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex != -1)
{
int id = e.Row.RowIndex + 1;
e.Row.Cells[0].Text = id.ToString();
}
}
注意这时最好把前台的第一列的表头该为“编号”，因为以前的第一列被“吃掉”了。
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
<asp:BoundField DataField="姓名" HeaderText="用户姓名" />
<asp:BoundField DataField="员工性别" HeaderText="性别" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
<asp:CommandField HeaderText="选择" ShowSelectButton="True" />
<asp:CommandField HeaderText="编辑" ShowEditButton="True" />
<asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
</Columns>
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
10.GridView实现自定义时间货币等字符串格式：
解决方法：
在asp.NET 2.0中，如果要在绑定列中显示比如日期格式等，如果用下面的方法是显示不了的
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HeaderText="CreationDate" />
主要是由于htmlencode属性默认设置为true,已防止XSS攻击，安全起见而用的，所以，可以有以下两种方法解决
1、
<asp :GridView ID="GridView1" runat="server">
<columns>
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HtmlEncode="false"
HeaderText="CreationDate" />
</columns>
</asp>
将htmlencode设置为false即可
另外的解决方法为，使用模版列
<asp :GridView ID="GridView3" runat="server" >
<columns>
<asp :TemplateField HeaderText="CreationDate" >
<edititemtemplate>
<asp :Label ID="Label1" runat="server"
Text='<%# Eval("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</edititemtemplate>
<itemtemplate>
<asp :Label ID="Label1" runat="server"
Text=’<%# Bind("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</itemtemplate>
</asp>
</columns>
</asp>
前台代码：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"
DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="身份证号码" ReadOnly="True" SortExpression="身份证号码" />
<asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />
<asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
<asp:BoundField DataField="出生日期" HeaderText="出生日期" SortExpression="出生日期" />
<asp:BoundField DataField="起薪" HeaderText="起薪" SortExpression="起薪" />
</Columns>
<FooterStyle BackColor="White" ForeColor="#000066" />
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"
SelectCommand="SELECT top 5 [出生日期], [起薪], [身份证号码], [姓名], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>
附录-常用格式化公式：
{0:C} 货币；
{0:D4}由0填充的4个字符宽的字段中显示整数；
{0:000.0}四舍五入小数点保留第几位有效数字；
{0:N2}小数点保留2位有效数字；{0:N2}% 小数点保留2位有效数字加百分号；
{0:D}长日期；{0:d}短日期；{0:yy-MM-dd} 例如07-3-25；；{0:yyyy-MM-dd} 例如2007-3-25
