Asp.net GridView使用大全(分页实现)

GridView自带的分页功能实现：

要实现GrdView分页的功能
操作如下：
1、更改GrdView控件的AllowPaging属性为true。
2、更改GrdView控件的PageSize属性为 任意数值（默认为10）
3、更改GrdView控件的PageSetting->Mode为Numeric等（默认为Numeric）该属性为分页样式。
GridView属性设置好了，从页面上也能看到分页样式。

现在开始实现分页的功能：

1、在<<asp:GridView ID=......>后添加，OnPageIndexChanging="GridView1_PageIndexChanging"
2、在对应的aspx.cs中添加：
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
InitPage(); //重新绑定GridView数据的函数
}
3、
GridView1.PageIndex = e.NewPageIndex;
完了之后再重新绑定一下GridView。

GridView添加CheckBox列实现全选/全部取消功能

首先GridView编辑模版，在模板上添加CheckBox控件，之后将新添加列字段转换为TemplateFiled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();
 }
}

<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:BoundField DataField="姓名" HeaderText="用户姓名" SortExpression="姓名"/> <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" SortExpression="家庭住址"/> </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>
 <asp:CheckBox ID="CheckBox2" runat="server" AutoPostBack="True" Font-Size="9pt" OnCheckedChanged="CheckBox2_CheckedChanged"
 Text="全选" />
 <asp:Button ID="Button1" runat="server" Font-Size="9pt" Text="取消" onClick="Button1_Click" />
 <asp:Button ID="Button2" runat="server" Font-Size="9pt" Text="删除" onClick="Button2_Click" />
