鼠標移到GridView某一行時改變該行的背景色方法一
鼠標移到GridView某一行時改變該行的背景色方法二
GridView實現刪除時彈出確認對話框
GridView實現自動編號
GridView實現自定義時間貨幣等字符串格式
GridView實現用「...」代替超長字符串
GridView通常換行與強制換行
GridView顯示隱藏某一列
GridView彈出新頁面/彈出新窗口
GridView固定表頭(不用javascript只用CSS，2行代碼，很好用)
GridView合併表頭多重表頭無錯完美版（以合併3列3行舉例）
GridView突出顯示某一單元格（例如金額低於多少，分數不及格等）
GridView加入自動求和求平均值小計
GridView數據導入Excel/Excel數據讀入GridViewjavascript
1.GridView無代碼分頁排序：html
效果圖：java
1.AllowSorting設爲True，aspx代碼中是AllowSorting="True"；
2.默認1頁10條，若是要修改每頁條數，修改PageSize便可，在aspx代碼中是PageSize="12"。
3.默認的是單向排序的，右擊GridView彈出「屬性」，選擇AllowSorting爲True便可。sql
2.GridView選中，編輯，取消，刪除：數據庫
效果圖：express

7.鼠標移到GridView某一行時改變該行的背景色方法二：
效果圖：
作法：和上面的同樣就是代碼不一樣
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//int i;
////執行循環，保證每條數據均可以更新
//for (i = 0; i < GridView1.Rows.Count; i++)
//{

// //當鼠標移開時還原背景色
// e.Row.Attributes.Add(" "this.style.backgroundColor=c");
// }
//}
//若是是綁定數據行
if (e.Row.RowType == DataControlRowType.DataRow)
{
//鼠標通過時，行背景色變
e.Row.Attributes.Add(" "this.style.backgroundColor='#E6F5FA'");
//鼠標移出時，行背景色變
e.Row.Attributes.Add(" "this.style.backgroundColor='#FFFFFF'");
}
}
8.GridView實現刪除時彈出確認對話框：
效果圖：

在後臺的GridView1_RowDataBound()方法添加代碼，最後代碼以下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//若是是綁定數據行
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(" "javascript:return confirm('你確認要刪除：\"" + e.Row.Cells[1].Text + "\"嗎?')");
}
}
}
9.GridView實現自動編號：
效果圖：
實現方法：
雙擊GridView的OnRowDataBound事件；
在後臺的GridView1_RowDataBound()方法添加代碼，最後代碼以下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//若是是綁定數據行 //清清月兒http://blog.csdn.net/21aspnet
if (e.Row.RowType == DataControlRowType.DataRow)
{
////鼠標通過時，行背景色變
//e.Row.Attributes.Add(" "this.style.backgroundColor='#E6F5FA'");
////鼠標移出時，行背景色變
//e.Row.Attributes.Add(" "this.style.backgroundColor='#FFFFFF'");
////當有編輯列時，避免出錯，要加的RowState判斷
//if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
//{
// ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add(" "javascript:return confirm('你確認要刪除：\"" + e.Row.Cells[1].Text + "\"嗎?')");
//}
}
if (e.Row.RowIndex != -1)
{
int id = e.Row.RowIndex + 1;
e.Row.Cells[0].Text = id.ToString();
}
}
注意這時最好把前臺的第一列的表頭該爲「編號」，由於之前的第一列被「吃掉」了。

10.GridView實現自定義時間貨幣等字符串格式：
效果圖：
圖1-未格式化前
圖2-格式化後
解決方法：
在asp.net 2.0中，若是要在綁定列中顯示好比日期格式等，若是用下面的方法是顯示不了的
</asp:GridView>
10.GridView實現自定義時間貨幣等字符串格式：
效果圖：
圖1-未格式化前
圖2-格式化後
解決方法：
在asp.net 2.0中，若是要在綁定列中顯示好比日期格式等，若是用下面的方法是顯示不了的
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HeaderText="CreationDate" />
主要是因爲htmlencode屬性默認設置爲true,已防止XSS***，安全起見而用的，因此，能夠有如下兩種方法解決
一、
<asp :GridView ID="GridView1" runat="server">
<columns>
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HtmlEncode="false"
HeaderText="CreationDate" />
</columns>
</asp>
將htmlencode設置爲false便可
另外的解決方法爲，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>

SelectCommand="Select top 5 [出生日期], [起薪], [×××號碼], [姓名], [家庭住址], [郵政編碼] FROM [飛狐工做室]" DataSourceMode="DataReader"></asp:SqlDataSource>
附錄-經常使用格式化公式：
{0:C} 貨幣；
{0:D4}由0填充的4個字符寬的字段中顯示整數；
{0:000.0}四捨五入小數點保留第幾位有效數字；
{0:N2}小數點保留2位有效數字；{0:N2}% 小數點保留2位有效數字加百分號；
{0:D}長日期；{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實現用「...」代替超長字符串：
效果圖：
解決方法：數據綁定後過濾每一行便可
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
DataRowView mydrv;
string gIntro;
if (GridView1.PageIndex == 0)
{
mydrv = myds.Tables["飛狐工做室"].DefaultView[i];//表名
gIntro = Convert.ToString(mydrv["家庭住址"]);//所要處理的字段
GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
}
else
{
mydrv = myds.Tables["飛狐工做室"].DefaultView[i + (5 * GridView1.PageIndex)];
gIntro = Convert.ToString(mydrv["家庭住址"]);
GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
}
}
調用的方法：
public string SubStr(string sString, int nLeng)
{
if (sString.Length <= nLeng)
{
return sString;
}
string sNewStr = sString.Substring(0, nLeng);
sNewStr = sNewStr + "...";
return sNewStr;
}

11.GridView通常換行與強制換行：
效果圖：
首先設置<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" ItemStyle-Width="100" />
gridview裏有一列綁定的數據很長，顯示的時候在一行裏面顯示，頁面拉得很寬。
緣由是連續英文段爲一個總體致使的，在RowDataBound中添加上了一句e.Row.Cells[2].Style.Add("word-break", "break-all")就能夠。
若是要給全部的列增長此屬性：
protected void Page_Load(object sender, EventArgs e)
{
//正常換行
GridView1.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");
//下面這行是自動換行
GridView1.Attributes.Add("style", "word-break:break-all;word-wrap:break-word");
if (!IsPostBack)
{
bind();//調用數據綁定便可
}
}
總之：善用CSS的word-break:break-all;word-wrap:break-word屬性便可，這個屬性是通用的對於頑固的南換行問題均可以解決，不侷限於GridView。
12.GridView顯示隱藏某一列：
本方案爲月兒首創，不一樣於網上其餘方式，我以爲用一個CheckBox更人性化，這樣能夠隱藏沒必要要的列，讓用戶本身選擇須要出現的列，在處理多列時這是一個很好的解決方案！
效果圖：
圖1-開始
圖2-點擊顯示的CheckBox後
解決方案：
public void bind()
{
string sqlstr = "select top 5 * from 飛狐工做室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飛狐工做室");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "×××號碼" };
GridView1.DataBind();
sqlcon.Close();
GridView1.Columns[3].Visible = false;//一開始隱藏
CheckBox1.Checked = false;//若是不這樣後面的代碼會把他True
}
雙擊CheckBox1，在CheckedChanged方法裏寫上代碼，最後代碼以下：
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;
Response.Write("GridView1的第4列如今的顯示隱藏狀態是："+GridView1.Columns[3].Visible.ToString());
}
注意：CheckBox1的AutoPostBack要True！
後臺所有代碼以下：

using System.Configuration;

using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

ViewState["OrderDire"] = "ASC";
bind();
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{

}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{

sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
bind();
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
sqlcon = new SqlConnection(strCon);
string sqlstr = "update 飛狐工做室 set 姓名='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',家庭住址='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + "' where ×××號碼='"
+ GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
sqlcom=new SqlCommand(sqlstr,sqlcon);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
GridView1.EditIndex = -1;
bind();
}
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
bind();
}
public void bind()
{
string sqlstr = "select top 5 * from 飛狐工做室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飛狐工做室");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "×××號碼" };
GridView1.DataBind();
sqlcon.Close();
GridView1.Columns[3].Visible = false;
CheckBox1.Checked = false;
}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;
Response.Write("GridView1的第4列如今的顯示隱藏狀態是："+GridView1.Columns[3].Visible.ToString());
}
}

13.GridView彈出新頁面/彈出制定大小位置新窗口：
效果圖：
方案一：簡單的方法，新窗口不固定大小
<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="×××號碼" HeaderText="編號" ReadOnly="True" />
<asp:BoundField DataField="郵政編碼" HeaderText="郵政編碼" SortExpression="郵政編碼" />
<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="選擇" ShowSelectButton="True" />
<asp:CommandField HeaderText="編輯" ShowEditButton="True" />
<asp:CommandField HeaderText="刪除" 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是連接的字段名，DataNavigateUrlFormatString是路徑。
方案二：精確控制彈出窗口大小位置
<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>
使用的是結合javascript的window.open方法，關於window.open的參數網上有不少帖子，本站也有許多參考

14.GridView固定表頭(不用javascript只用CSS!，很好用)：
效果圖：
代碼：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >

<style>
.Freezing
{
position:relative ;
table-layout:fixed;
top:expression(this.offsetParent.scrollTop);
z-index: 10;
}
.Freezing th{text-overflow:ellipsis;overflow:hidden;white-space: nowrap;padding:2px;}
</style>
</head>
<body style="font-size=12px">
<form id="form1" runat="server">
<div style="overflow-y: scroll; height: 200px;width:300px" id="dvBody">
<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" OnRowCreated="GridView1_RowCreated" >
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
<asp:BoundField DataField="×××號碼" HeaderText="編號" ReadOnly="True" />
<asp:BoundField DataField="郵政編碼" HeaderText="郵政編碼" SortExpression="郵政編碼" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
<asp:BoundField DataField="姓名" HeaderText="姓名" />
</Columns>
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" CssClass="ms-formlabel DataGridFixedHeader"/>
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" CssClass="Freezing"/>
</asp:GridView>
</div>
</form>
</body>
</html>
用法：CSS設如上的樣式，HeaderStyle加CssClass="Freezing，套住GridView的Div設置高度寬度 <div style="overflow-y: scroll; height: 200px;width:200px" >
