        {
            DropDownList ddl;
            if (!IsPostBack)
            {
                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");
                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;
                    }

                    {
                        ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");

                    }
                }
                sqlcon.Close();
            }
        }
        public SqlDataReader ddlbind()
        {
            string sqlstr = "select distinct 员工性别 from 飞狐工作室";

            SqlCommand sqlcom = new SqlCommand(sqlstr, sqlcon);
            sqlcon.Open();
            return sqlcom.ExecuteReader();
        }

    前台主要代码:

                            <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
                            <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
                        </asp:GridView>


    5.GridView和CheckBox结合:

    效果图:



    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
    {
    //清清月儿http://blog.csdn.net/21aspnet
        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: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>

                            <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" />


    6.鼠标移到GridView某一行时改变该行的背景色方法一:

    效果图:


    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)
        {
            int i;
            //执行循环,保证每条数据都可以更新
            for (i = 0; i < GridView1.Rows.Count; i++)
            {
                //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>
