    {

        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;

            }

        }

    }

    {

        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: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" />

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="" >

<head runat="server">

    <title>实现鼠标划过改变GridView的行背景色 清清月儿 </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>
