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<
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：复制代码 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 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：复制代码 代码如下:
