GridView 使用方法总结 （一）
下载全部代码 http://www.sufeinet.com/thread-431-1-1.html
今天到csdn发现一篇让我忍不住要转的文章，虽然作者写的都是基础，但是对于初学者来说帮助还是很大的，原文件作者是：csdn.net的清清月儿 她的主页 http://blog.csdn.net/21aspnet/ 。
看了文章我感觉特别不错，但是也发现了一些问题，首先是代码没有放到代码标记里，看起来不是很好看，还有一些代码没有注释新手看起来会很不方便，所以我想给他规范化一下，赵哥昨天才讲过博客的版面美观于否是很重要的，让大家看着方便，也算是为刚加入的微软社区精英计划出把力吧，为了保留作者的权力，我没有改动代码的实现 方法，只是把代码规范化了一下下，呵呵，在这里再次感谢作者清清月儿
快速预览：
GridView无代码分页排序
GridView选中，编辑，取消，删除
GridView正反双向排序
GridView和下拉菜单DropDownList结合
GridView和CheckBox结合
鼠标移到GridView某一行时改变该行的背景色方法一
鼠标移到GridView某一行时改变该行的背景色方法二
GridView实现删除时弹出确认对话框
GridView实现自动编号
GridView实现自定义时间货币等字符串格式
GridView实现用“...”代替超长字符串
GridView一般换行与强制换行
GridView显示隐藏某一列
GridView弹出新页面/弹出新窗口
GridView固定表头(不用javascript只用CSS，2行代码，很好用)
GridView合并表头多重表头无错完美版（以合并3列3行举例）
GridView突出显示某一单元格（例如金额低于多少，分数不及格等）
GridView加入自动求和求平均值小计
GridView数据导入Excel/Excel数据读入GridView
1.GridView无代码分页排序：
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：

6.鼠标移到GridView某一行时改变该行的背景色方法一：
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：
代码
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)
{

7.鼠标移到GridView某一行时改变该行的背景色方法二：
做法：和上面的一样就是代码不同
代码
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' " );
}
}
{
// 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：
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：
代码
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?') " );
}
}
}
{
// 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：
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：
代码
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();
}
}
{
// 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。

10.GridView实现自定义时间货币等字符串格式：
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" />
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、
代码
<
asp
:GridView ID
="GridView1"
runat
="server"
>
< columns >
< asp :BoundField DataField ="CreationDate"
DataFormatString ="{0:M-dd-yyyy}"
HtmlEncode ="false"
HeaderText ="CreationDate" />
</ columns >
</ asp >
< 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
代码
<
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 >
< 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 >

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：
解决方法：数据绑定后过滤每一行即可
代码
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(mydrv[ " 家庭住址 " ]); // 所要处理的字段
GridView1.Rows[i].Cells[ 3 ].Text = SubStr(gIntro, 2 );
}
else
{
mydrv = myds.Tables[ " 飞狐工作室 " ].DefaultView[i + ( 5 * GridView1.PageIndex)];
gIntro = Convert.ToString(mydrv[ " 家庭住址 " ]);
GridView1.Rows[i].Cells[ 3 ].Text = SubStr(gIntro, 2 );
}
}
{
DataRowView mydrv;
string gIntro;
if (GridView1.PageIndex == 0 )
{
mydrv = myds.Tables[ " 飞狐工作室 " ].DefaultView[i]; // 表名
gIntro = Convert.ToString(mydrv[ " 家庭住址 " ]); // 所要处理的字段
GridView1.Rows[i].Cells[ 3 ].Text = SubStr(gIntro, 2 );
}
else
{
mydrv = myds.Tables[ " 飞狐工作室 " ].DefaultView[i + ( 5 * GridView1.PageIndex)];
gIntro = Convert.ToString(mydrv[ " 家庭住址 " ]);
GridView1.Rows[i].Cells[ 3 ].Text = SubStr(gIntro, 2 );
}
}
调用的方法：
代码
public
string
SubStr(
string
sString,
int
nLeng)
{
if (sString.Length <= nLeng)
{
return sString;
}
string sNewStr = sString.Substring( 0 , nLeng);
sNewStr = sNewStr + " ... " ;
return sNewStr;
}
{
if (sString.Length <= nLeng)
{
return sString;
}
string sNewStr = sString.Substring( 0 , nLeng);
sNewStr = sNewStr + " ... " ;
return sNewStr;
}

if (GridView1.PageIndex == 0 )
{
mydrv = myds.Tables[ " 飞狐工作室 " ].DefaultView[i];
gIntro = Convert.ToString(mydrv[ " 家庭住址 " ]);
GridView1.Rows[i].Cells[ 3 ].Text = SubStr(gIntro, 2 );
}
else
{

11.GridView一般换行与强制换行：
首先设置<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" ItemStyle-Width="100" />
gridview里有一列绑定的数据很长，显示的时候在一行里面显示，页面拉得很宽。
原因是连续英文段为一个整体导致的，在RowDataBound中添加上了一句e.Row.Cells[2].Style.Add("word-break", "break-all")就可以。
如果要给所有的列增加此属性：
代码
protected
void
Page_Load(
object
sender, EventArgs e)
{
// 正常换行
GridView1.Attributes.Add( " style " , " word-break:keep-all;word-wrap:normal " );
// 下面这行是自动换行
GridView1.Attributes.Add( " style " , " word-break:break-all;word-wrap:break-word " );
if ( ! IsPostBack)
{
bind(); // 调用数据绑定即可
}
}
{
// 正常换行
GridView1.Attributes.Add( " style " , " word-break:keep-all;word-wrap:normal " );
// 下面这行是自动换行
GridView1.Attributes.Add( " style " , " word-break:break-all;word-wrap:break-word " );
if ( ! IsPostBack)
{
bind(); // 调用数据绑定即可
}
}
总之：善用CSS的word-break:break-all;word-wrap:break-word属性即可，这个属性是通用的对于顽固的南换行问题都可以解决，不局限于GridView。
12.GridView显示隐藏某一列：
本方案为月儿独创，不同于网上其他方式，我觉得用一个CheckBox更人性化，这样可以隐藏不必要的列，让用户自己选择需要出现的列，在处理多列时这是一个很好的解决方案！
效果图：
图1-开始
图2-点击显示的CheckBox后
解决方案
代码
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, " 飞狐工作室 " );
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string [] { " 身份证号码 " };
GridView1.DataBind();
sqlcon.Close();
GridView1.Columns[ 3 ].Visible = false ; // 一开始隐藏
CheckBox1.Checked = false ; // 如果不这样后面的代码会把他True
}
{
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.DataKeyNames = new string [] { " 身份证号码 " };
GridView1.DataBind();
sqlcon.Close();
GridView1.Columns[ 3 ].Visible = false ; // 一开始隐藏
CheckBox1.Checked = false ; // 如果不这样后面的代码会把他True
}
双击CheckBox1，在CheckedChanged方法里写上代码，最后代码如下：
代码
protected
void
CheckBox1_CheckedChanged(
object
sender, EventArgs e)
{
GridView1.Columns[ 3 ].Visible =! GridView1.Columns[ 3 ].Visible;
Response.Write( " GridView1的第4列现在的显示隐藏状态是： " + GridView1.Columns[ 3 ].Visible.ToString());
}
{
GridView1.Columns[ 3 ].Visible =! GridView1.Columns[ 3 ].Visible;
Response.Write( " GridView1的第4列现在的显示隐藏状态是： " + GridView1.Columns[ 3 ].Visible.ToString());
}
注意：CheckBox1的AutoPostBack要True！

13.GridView弹出新页面/弹出制定大小位置新窗口：
方案一：简单的方法，新窗口不固定大小
代码
<
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" >
< FooterStyle BackColor ="White" ForeColor ="#000066" />
< Columns >
< asp:BoundField DataField ="身份证号码" HeaderText ="编号" ReadOnly ="True" />
< asp:BoundField DataField ="邮政编码" HeaderText ="邮政编码" SortExpression ="邮政编码" />
< asp:BoundField DataField ="家庭住址" HeaderText ="家庭住址" />
< asp:HyperLinkField HeaderText ="姓名" Text ="姓名" DataNavigateUrlFields ="姓名" DataNavigateUrlFormatString ="Default6.aspx?GoodsID={0}" Target ="mainframe" NavigateUrl ="~/Default6.aspx" DataTextField ="姓名" >
</ asp:HyperLinkField >
< 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 >
OnRowUpdating ="GridView1_RowUpdating" OnRowCancelingEdit ="GridView1_RowCancelingEdit" BackColor ="White" BorderColor ="#CCCCCC" BorderStyle ="None" BorderWidth ="1px" Font-Size ="12px" >
< FooterStyle BackColor ="White" ForeColor ="#000066" />
< Columns >
< asp:BoundField DataField ="身份证号码" HeaderText ="编号" ReadOnly ="True" />
< asp:BoundField DataField ="邮政编码" HeaderText ="邮政编码" SortExpression ="邮政编码" />
< asp:BoundField DataField ="家庭住址" HeaderText ="家庭住址" />
< asp:HyperLinkField HeaderText ="姓名" Text ="姓名" DataNavigateUrlFields ="姓名" DataNavigateUrlFormatString ="Default6.aspx?GoodsID={0}" Target ="mainframe" NavigateUrl ="~/Default6.aspx" DataTextField ="姓名" >
</ asp:HyperLinkField >
< 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 >
DataNavigateUrlFields是链接的字段名，DataNavigateUrlFormatString是路径。
方案二：精确控制弹出窗口大小位置
代码
<
asp:HyperLinkColumn
DataNavigateUrlField
="EmployeeID"
DataNavigateUrlFormatString
="javascript:varwin=window.open('detail.aspx?ID={0}',null,'width=300,height=200');window.Close();"
DataTextField ="LastName" HeaderText ="LastName" ></ asp:HyperLinkColumn >
DataTextField ="LastName" HeaderText ="LastName" ></ asp:HyperLinkColumn >
使用的是结合javascript的window.open方法，关于window.open的参数网上有很多帖子，本站也有许多参考
弹出窗口大全 http://blog.csdn.net/21aspnet/archive/2004/10/25/150231.aspx 即可！
清清月儿的文章太长了这篇我先写到这里，明天写一下面的几个，然后再说说自己的解决方案，因为这里没有用Sqlhepler类，我的方法里都 改成了Sqlhelper类来实现
