1.GridView中使用超链接的技巧
  GridView中的超级链接，可以设置一个模版列，放入超级链接的控件，设置绑定参数即可。
数据绑定方式有两种，如下示例：
◆Eval方式     <%# Eval("id") %>
◆Bind方式    <%# Bind("id","~/info.aspx?id={0}") %>
推荐使用第一种方式，可以在一个<%# %>里放入多个绑定，而第二种只能如此绑定一个值
<%# Eval("id") + ":" + Eval("name")%>

做超级链接的控件，我们也有多种选择：
◆asp:LinkButton
示例
<asp:LinkButton ID="LinkButton2" OnClientClick=<%# "window.open('info.aspx?id=" + Eval("id") + "&name=" + Eval("name") + "')" %> runat="server"><%# "LinkButton方式绑定:" + Eval("id") %></asp:LinkButton>
◆asp:HyperLink
示例
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "~/info.aspx?id=" + Eval("id") + "&name=" + Eval("name") %>' Text='<%#"HyperLink控件:" + Eval("id") %>'></asp:HyperLink>
◆a标签
示例
<a href='<%# "info.aspx?id=" + Eval("id") + "&name=" + Eval("name") %>'>a标签:<%# Eval("id") + ":" + Eval("name")%></a>
<a href='Javascript:alert("<%# "~/info.aspx?id=" + Eval("id") + "&name=" + Eval("name") %>")'>链接js事件:<%# Eval("id") %></a>

LinkButton 不好设置，推荐使用HyperLink或者a的方式，简单实用。特别是a标签，使用Javascript的方法也比较方便。
 补充：
<asp:LinkButton ID="LinkButton3" runat="server" PostBackUrl='<%# "~/Default.aspx?id=" + Eval("FUserID") %>'
CausesValidation="False" Text="跳转编辑"></asp:LinkButton>

2.gridview模板列加htmlinputcheckbox的取值
①aspx文件：
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
            DataKeyNames="OrderID,ProductID" DataSourceID="SqlDataSource1" EmptyDataText="111">
            <Columns>
                <asp:BoundField DataField="OrderID" HeaderText="OrderID" ReadOnly="True" SortExpression="OrderID" />
                <asp:BoundField DataField="ProductID" HeaderText="ProductID" ReadOnly="True" SortExpression="ProductID" />
                <asp:BoundField DataField="UnitPrice" HeaderText="UnitPrice" SortExpression="UnitPrice" DataFormatString="{0:C}" />
                <asp:BoundField DataField="Quantity" HeaderText="Quantity" SortExpression="Quantity" />
                <asp:BoundField DataField="Discount" HeaderText="Discount" SortExpression="Discount" />
                <asp:ImageField DataImageUrlField="OrderID" DataImageUrlFormatString="/{0}.gif" HeaderText="pic">
                </asp:ImageField>
                <asp:TemplateField FooterText="id">
                    <ItemTemplate>
                        &nbsp;<input id="Checkbox1" runat="server" type="checkbox" value='<%# Eval("OrderID") %>' />                      
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
        <%=gridview1.PageIndex +1%>of<%=GridView1.PageCount%>
②cs文件：
string str1;
HtmlInputCheckBox cb;
str1="";
for(int i=0;i<GridView1.Rows.Count-1;i++)
{
  cb=GridView1.Rows(i).Cells(6).FindControl("Checkbox1");
  if(cb.Checked)
  {
    if(str1=="")
    {
      str1=cb.Value;
    }
    else
    {
      str1=str1+","+cb.Value;
    }
  }
}
Label1.Text=str1;

3.gridview模板列绑定gridview
①aspx文件：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ProductID"
            DataSourceID="SqlDataSource1">
            <Columns>
                <asp:BoundField DataField="ProductID" HeaderText="ProductID" InsertVisible="False"
                    ReadOnly="True" SortExpression="ProductID" />
                <asp:BoundField DataField="ProductName" HeaderText="ProductName" SortExpression="ProductName" />
                <asp:TemplateField HeaderText="detail">
                    <ItemTemplate>
                        &nbsp;&nbsp;&nbsp;
                        <asp:GridView ID="GridView2" runat="server">
                        </asp:GridView>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
②cs文件：
protected void GridView1_RowDataBound(object sender,System.Web.UI.WebControls.GridViewRowEventArgs e)
{
  if(e.Row.RowType==DataControlRowType.DataRow)
  {
    SqlDataSource2.SelectParameters.Clear();
    SqlDataSource2.SelectParameters.Add("id",e.Row.Cells(0).Text);
    GridView gv;
    gv=e.Row.Cells(2).FindControl("GridView2");
    gv.DataSource=this.SqlDataSource2;
    gv.DataBind();
  }
}

4.GridView更新和删除显示提示信息

1.GridView无代码分页排序 ：

效果图：

1.AllowSorting设为True，aspx代码中是AllowSorting="True"；
2.默认1页10条，如果要修改每页条数，修改PageSize即可，在aspx代码中是PageSize="12"。
3.默认的是单向排序的，右击GridView弹出“属性”，选择AllowSorting为True即可。

2.GridView选中，编辑，取消，删除：

        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");
            }
        }

    }

7 .鼠标移到GridView某一行时改变该行的背景色方法二：

效果图：

做法：和上面的一样就是代码不同
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");
        //    }
        //}
        //如果是绑定数据行
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            //鼠标经过时，行背景色变
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            //鼠标移出时，行背景色变
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
        }

    }

8 .GridView实现删除时弹出确认对话框：

效果图：

实现方法：
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)
    {
        //如果是绑定数据行
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
             if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {
                ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text + "\"吗?')");
            }
        }

    }

9 .GridView实现自动编号：

效果图：

实现方法：
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)
    {
        //如果是绑定数据行 //清清月儿http://blog.csdn.net/21aspnet 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ////鼠标经过时，行背景色变
            //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            ////鼠标移出时，行背景色变
            //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

            ////当有编辑列时，避免出错，要加的RowState判断
            //if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            //{
            //    ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text + "\"吗?')");
            //}

        }
        if (e.Row.RowIndex != -1)
        {
            int id = e.Row.RowIndex + 1;
            e.Row.Cells[0].Text = id.ToString();
        }

    }

注意这时最好把前台的第一列的表头该为“编号”，因为以前的第一列被“吃掉”了。
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
                        OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
                        <FooterStyle BackColor="White" ForeColor="#000066" />
                        <Columns>
                            <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
                            <asp:BoundField DataField="姓名" HeaderText="用户姓名" />
                            <asp:BoundField DataField="员工性别" HeaderText="性别" />
                            <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
                            <asp:CommandField HeaderText="选择" ShowSelectButton="True" />
                            <asp:CommandField HeaderText="编辑" ShowEditButton="True" />
                            <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
                        </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>

10 .GridView实现自定义时间货币等字符串格式：

效果图：
图1-未格式化前

图2-格式化后

解决方法：
在asp.net 2.0中，如果要在绑定列中显示比如日期格式等，如果用下面的方法是显示不了的

<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HeaderText="CreationDate" />

主要是由于htmlencode属性默认设置为true,已防止XSS攻击，安全起见而用的，所以，可以有以下两种方法解决

1、

<asp :GridView ID="GridView1" runat="server">
<columns>
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HtmlEncode="false"
HeaderText="CreationDate" />
</columns>
</asp>

将htmlencode设置为false即可

另外的解决方法为，使用模版列

<asp :GridView ID="GridView3" runat="server" >
<columns>
<asp :TemplateField HeaderText="CreationDate" >
<edititemtemplate>
<asp :Label ID="Label1" runat="server"
Text='<%# Eval("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</edititemtemplate>
<itemtemplate>
<asp :Label ID="Label1" runat="server"
Text=’<%# Bind("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</itemtemplate>
</asp>
</columns>
</asp>

前台代码：
<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="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
                <asp:BoundField DataField="出生日期" HeaderText="出生日期" SortExpression="出生日期" />
                <asp:BoundField DataField="起薪" HeaderText="起薪" SortExpression="起薪" />
            </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 [出生日期], [起薪], [身份证号码], [姓名], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>

附录-常用格式化公式：
{0:C}  货币；
{0:D4}由0填充的4个字符宽的字段中显示整数；
{0:000.0}四舍五入小数点保留第几位有效数字；
{0:N2}小数点保留2位有效数字；{0:N2}%   小数点保留2位有效数字加百分号；
{0:D}长日期；{0:d}短日期；{0:yy-MM-dd}   例如07-3-25；；{0:yyyy-MM-dd}  例如2007-3-25

 11 .GridView实现用“...”代替超长字符串：

效果图：

解决方法：数据绑定后过滤每一行即可
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
        {
            DataRowView mydrv;
            string gIntro;
            if (GridView1.PageIndex == 0)
            {
                mydrv = myds.Tables["飞狐工作室"].DefaultView[i];//表名
                gIntro = Convert.ToString(mydr
