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

    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();
    }
}
