对于gridview学NET的同学再熟悉不过，但是其中功能事件是否能编码熟练实现？前不久看点博文，以及资料，综合自己的一些想法，汇总如下：

数据库设计如下，以便更好理解：

设计：

实现：

GridView无代码分页排序

小实例：

AllowSorting设为True，aspx代码中是AllowSorting="True"；

运行结果：

GridView选中，编辑，取消，删除

小实例：

GridView.aspx

复制代码代码如下:
<asp:GridView ID="GridView1" runat="server" Height="138px" Width="1117px"
AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"
onpageindexchanging="GridView1_PageIndexChanging"
onrowcancelingedit="GridView1_RowCancelingEdit"
onrowdeleting="GridView1_RowDeleting" onrowediting="GridView1_RowEditing"
onrowupdating="GridView1_RowUpdating">
<Columns>

<asp:TemplateField HeaderText="身份证号" SortExpression="pid">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("pid") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<%-- <asp:BoundField DataField="pid" HeaderText="身份证号" SortExpression="pid" />--%>
<asp:BoundField DataField="pname" HeaderText="姓名" SortExpression="pname" />
<asp:BoundField DataField="psex" HeaderText="性别" SortExpression="psex" />
<asp:BoundField DataField="padress" HeaderText="地址" SortExpression="padress" />
<asp:BoundField DataField="pyoubiao" HeaderText="邮编" SortExpression="pyoubiao" />
<asp:BoundField DataField="pprice" HeaderText="工资起价" SortExpression="pprice" />
<asp:CommandField HeaderText="选择" ShowSelectButton="True" />
<asp:CommandField HeaderText="编辑" ShowEditButton="True" />
<asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
</Columns>
<EmptyDataRowStyle BackColor="Red" />
<HeaderStyle BackColor="#0000CC" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#864" HorizontalAlign="Center" ForeColor="White"/>
</asp:GridView>

GridView.aspx.cs
复制代码代码如下:
//公有数据
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlcon"].ConnectionString);
SqlCommand cmd;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind(); //正常绑定
}
}

/// <summary>
/// 主题：绑定数据，查询显示个人信息
/// 时间：2012年11月21日14:54:13
/// 描述：通过简单的方法绑定，实现数据显示
/// 作者：小伙
/// </summary>
public void bind()
{
//数据连接web.config中已配置的数据
SqlDataAdapter da = new SqlDataAdapter("select top 5 * from person", con);//使用数据适配器内置查询，自动开闭数据库
DataSet ds = new DataSet();//使用数据集，采取断开式访问数据
da.Fill(ds, "person");
GridView1.DataSource = ds;
GridView1.DataKeyNames=new string[]{"pid"};//设置主键
GridView1.DataBind();
}

//实现分页
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
this.bind();
}
//删除
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string sqlstr = "delete from person where pid='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
con.Open();
cmd = new SqlCommand(sqlstr, con);
cmd.ExecuteNonQuery();
con.Close();
bind();

}
//取消编辑
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
bind();
}
//编辑
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
bind();
}

//更新
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string sqlstr = "update person set pname='"
+((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',psex='"
+((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim()+"',padress='"
+((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim()+"',pyoubiao='"
+((TextBox)(GridView1.Rows[e.RowIndex].Cells[4].Controls[0])).Text.ToString().Trim()+"',pprice='"
+((TextBox)(GridView1.Rows[e.RowIndex].Cells[5].Controls[0])).Text.ToString().Trim()+"' where pid='"
+GridView1.DataKeys[e.RowIndex].Value.ToString()+"'";
cmd = new SqlCommand(sqlstr, con);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
GridView1.EditIndex = -1;
bind();

}

运行结果：

运行初始页：

点击编辑：

更新后：

GridView正反双向排序

小实例：

运行结果：

排序前：

排序后：

GridView和下拉菜单DropDownList结合

小实例：

GridView.aspx

GridView.aspx.cs

复制代码代码如下:
//公有数据
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlcon"].ConnectionString);
SqlCommand cmd;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Drpbind();//dropdown绑定

}
}

//DropDownList绑定数据
DropDownList ddl;
public void Drpbind()
{
string sqlstr = "select top 5 * from person";
con.Open();
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, con);
DataSet ds = new DataSet();
myda.Fill(ds, "person");
GridView1.DataSource = ds;
GridView1.DataBind();
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
DataRowView mydrv = ds.Tables["person"].DefaultView[i];
if (Convert.ToString(mydrv["psex"]).Trim() == "男")
{
ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");
ddl.SelectedIndex = 0;

}
else if (Convert.ToString(mydrv["psex"]).Trim() == "女")
{
ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");
ddl.SelectedIndex = 1;
}
}
con.Close();

}

//GridView和下拉菜单DropDownList结合，前台性别列datasouce调用
public SqlDataReader ddlbind()
{

string sqlstr = "select distinct psex from person";//distinct只显示一次性别
using (cmd = new SqlCommand(sqlstr, con))
{
con.Close();
con.Open();
return cmd.ExecuteReader();
}
}

运行结果：

GridView1.DataSource = ds;
GridView1.DataKeyNames=new string[]{"pid"};//设置主键
GridView1.DataBind();
}

//利用CheckBox选中信息
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

鼠标移到GridView某一行时改变该行的背景色方法一

小实例：

GridView.aspx

复制代码代码如下:
//公有数据

{
//当鼠标停留时更改背景色
e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#999'");
//当鼠标移开时还原背景色

GridView.aspx.cs

复制代码代码如下:
//鼠标移动到某一行，改变改行颜色
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

//鼠标移出时，行背景色变
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#087'");
}
}

运行结果：

前台代码如上

GridView.aspx.cs

绑定显示数据代码如上，不再总结，以下只做主要代码：

复制代码代码如下:
//实现自动编号

{
#region
//如果是绑定数据行
if (e.Row.RowType == DataControlRowType.DataRow)

}
}
#endregion
if (e.Row.RowIndex != -1)
{
