[转]GridView 72般绝技
快速預(yù)覽：
GridView無(wú)代碼分頁(yè)排序
GridView選中，編輯，取消，刪除
GridView正反雙向排序
GridView和下拉菜單DropDownList結(jié)合
GridView和CheckBox結(jié)合
鼠標(biāo)移到GridView某一行時(shí)改變?cè)撔械谋尘吧椒ㄒ?br />鼠標(biāo)移到GridView某一行時(shí)改變?cè)撔械谋尘吧椒ǘ?br />GridView實(shí)現(xiàn)刪除時(shí)彈出確認(rèn)對(duì)話框
GridView實(shí)現(xiàn)自動(dòng)編號(hào)
GridView實(shí)現(xiàn)自定義時(shí)間貨幣等字符串格式
GridView實(shí)現(xiàn)用“...”代替超長(zhǎng)字符串
GridView一般換行與強(qiáng)制換行
GridView顯示隱藏某一列
GridView彈出新頁(yè)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合并表頭多重表頭無(wú)錯(cuò)完美版（以合并3列3行舉例）
GridView突出顯示某一單元格（例如金額低于多少，分?jǐn)?shù)不及格等）
GridView加入自動(dòng)求和求平均值小計(jì)
GridView數(shù)據(jù)導(dǎo)入Excel/Excel數(shù)據(jù)讀入GridView
1.GridView無(wú)代碼分頁(yè)排序：
效果圖：
1.AllowSorting設(shè)為T(mén)rue，aspx代碼中是AllowSorting="True"；
2.默認(rèn)1頁(yè)10條，如果要修改每頁(yè)條數(shù)，修改PageSize即可，在aspx代碼中是PageSize="12"。
3.默認(rèn)的是單向排序的，右擊GridView彈出“屬性”，選擇AllowSorting為T(mén)rue即可。
2.GridView選中，編輯，取消，刪除：
效果圖：

10.GridView實(shí)現(xiàn)自定義時(shí)間貨幣等字符串格式：
效果圖：
圖1-未格式化前
圖2-格式化后
解決方法：
在asp.net 2.0中，如果要在綁定列中顯示比如日期格式等，如果用下面的方法是顯示不了的
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HeaderText="CreationDate" />
主要是由于htmlencode屬性默認(rèn)設(shè)置為true,已防止XSS攻擊，安全起見(jiàn)而用的，所以，可以有以下兩種方法解決
1、
<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(shè)置為false即可
另外的解決方法為，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>

{0:C}? 貨幣；
{0:D4}由0填充的4個(gè)字符寬的字段中顯示整數(shù)；
{0:000.0}四舍五入小數(shù)點(diǎn)保留第幾位有效數(shù)字；

?11.GridView一般換行與強(qiáng)制換行：
效果圖：
首先設(shè)置<asp:BoundField DataField="家庭住址" HeaderText="家庭住址"? ItemStyle-Width="100" />
gridview里有一列綁定的數(shù)據(jù)很長(zhǎng)，顯示的時(shí)候在一行里面顯示，頁(yè)面拉得很寬。
原因是連續(xù)英文段為一個(gè)整體導(dǎo)致的，在RowDataBound中添加上了一句e.Row.Cells[2].Style.Add("word-break", "break-all")就可以。
如果要給所有的列增加此屬性：
?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(dòng)換行
??????? GridView1.Attributes.Add("style", "word-break:break-all;word-wrap:break-word");
??????? if (!IsPostBack)
??????? {
?????????????bind();//調(diào)用數(shù)據(jù)綁定即可
??????? }
??? }
總之：善用CSS的word-break:break-all;word-wrap:break-word屬性即可，這個(gè)屬性是通用的對(duì)于頑固的南換行問(wèn)題都可以解決，不局限于GridView。
?12.GridView顯示隱藏某一列：
本方案為月兒獨(dú)創(chuàng)，不同于網(wǎng)上其他方式，我覺(jué)得用一個(gè)CheckBox更人性化，這樣可以隱藏不必要的列，讓用戶自己選擇需要出現(xiàn)的列，在處理多列時(shí)這是一個(gè)很好的解決方案！
效果圖：
圖1-開(kāi)始
圖2-點(diǎn)擊顯示的CheckBox后
解決方案：
public void bind()
??? {
??????? string sqlstr = "select top 5 * from 飛狐工作室";
??????? sqlcon = new SqlConnection(strCon);
??????? SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
??????? DataSet myds = new DataSet();
??????? sqlcon.Open();
??????? myda.Fill(myds, "飛狐工作室");
??????? GridView1.DataSource = myds;
??????? GridView1.DataKeyNames = new string[] { "身份證號(hào)碼" };
??????? GridView1.DataBind();
??????? sqlcon.Close();
??????? GridView1.Columns[3].Visible = false;//一開(kāi)始隱藏
??????? CheckBox1.Checked = false;//如果不這樣后面的代碼會(huì)把他True
??? }
雙擊CheckBox1，在CheckedChanged方法里寫(xiě)上代碼，最后代碼如下：
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
??? {
???????? GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;
???????? Response.Write("GridView1的第4列現(xiàn)在的顯示隱藏狀態(tài)是："+GridView1.Columns[3].Visible.ToString());
??? }
注意：CheckBox1的AutoPostBack要True！

??????????????????????? <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
??????????????????? </asp:GridView>
DataNavigateUrlFields是鏈接的字段名，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(jié)合javascript的window.open方法，關(guān)于window.open的參數(shù)網(wǎng)上有很多帖子，本站也有許多參考
彈出窗口大全 http://blog.csdn.net/21aspnet/archive/2004/10/25/150231.aspx?? 即可！
