1.GridView無代碼分頁排序：

效果圖：

1.AllowSorting設(shè)為True，aspx代碼中是AllowSorting="True"；
2.默認1頁10條，如果要修改每頁條數(shù)，修改PageSize即可，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為True即可。

2.GridView選中，編輯，取消，刪除：

7.鼠標移到GridView某一行時改變該行的背景色方法二：

效果圖：

做法：和上面的一樣就是代碼不同
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
??? {
??????? //int i;
??????? 執(zhí)行循環(huán)，保證每條數(shù)據(jù)都可以更新
??????? //for (i = 0; i < GridView1.Rows.Count; i++)
??????? //{
??????? //??? //首先判斷是否是數(shù)據(jù)行
??????? //??? if (e.Row.RowType == DataControlRowType.DataRow)
??????? //??? {
??????? //??????? //當鼠標停留時更改背景色
??????? //??????? e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");
??????? //??????? //當鼠標移開時還原背景色
??????? //??????? e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
??????? //??? }
??????? //}
??????? //如果是綁定數(shù)據(jù)行
??????? if (e.Row.RowType == DataControlRowType.DataRow)
??????? {
??????????? //鼠標經(jīng)過時，行背景色變
??????????? e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
??????????? //鼠標移出時，行背景色變
??????????? e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
??????? }

??? }

8.GridView實現(xiàn)刪除時彈出確認對話框：

效果圖：

實現(xiàn)方法：
雙擊GridView的OnRowDataBound事件；
在后臺的GridView1_RowDataBound()方法添加代碼，最后代碼如下所示：

??? protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
??? {
??????? //如果是綁定數(shù)據(jù)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('你確認要刪除：/"" + e.Row.Cells[1].Text + "/"嗎?')");
??????????? }
??????? }

??? }

9.GridView實現(xiàn)自動編號：

效果圖：

實現(xiàn)方法：
雙擊GridView的OnRowDataBound事件；
在后臺的GridView1_RowDataBound()方法添加代碼，最后代碼如下所示：
??? protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
??? {
??????? //如果是綁定數(shù)據(jù)行 //清清月兒http://blog.csdn.net/21aspnet?
??????? if (e.Row.RowType == DataControlRowType.DataRow)
??????? {
??????????? 鼠標經(jīng)過時，行背景色變
??????????? //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
??????????? 鼠標移出時，行背景色變
??????????? //e.Row.Attributes.Add("onmouseout", "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("onclick", "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為“編號”，因為以前的第一列被“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="身份證號碼" HeaderText="編號" ReadOnly="True" />
??????????????????????????? <asp:BoundField DataField="姓名" HeaderText="用戶姓名" />
??????????????????????????? <asp:BoundField DataField="員工性別" HeaderText="性別" />
??????????????????????????? <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
??????????????????????????? <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>

10.GridView實現(xiàn)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屬性默認設(shè)置為true,已防止XSS攻擊，安全起見而用的，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>

附錄-常用格式化公式：
{0:C}? 貨幣；
{0:D4}由0填充的4個字符寬的字段中顯示整數(shù)；
{0:000.0}四舍五入小數(shù)點保留第幾位有效數(shù)字；
{0:N2}小數(shù)點保留2位有效數(shù)字；{0:N2}%?? 小數(shù)點保留2位有效數(shù)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(xiàn)用“...”代替超長字符串：

效果圖：

解決方法：數(shù)據(jù)綁定后過濾每一行即可
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
??????? {
??????????? DataRowView mydrv;
??????????? string gIntro;
??????????? if (GridView1.PageIndex == 0)
??????????? {
??????????????? mydrv = myds.Tables["飛狐工作室"].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["飛狐工作室"].DefaultView[i + (5 * GridView1.PageIndex)];
??????????????? gIntro = Convert.ToString(mydrv["家庭住址"]);
??????????????? GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
??????????? }
??????? }?

調(diào)用的方法：

??????? if (sString.Length <= nLeng)
??????? {
??????????? return sString;
??????? }
??????? string sNewStr = sString.Substring(0, nLeng);

?11.GridView一般換行與強制換行：

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，顯示的時候在一行里面顯示，頁面拉得很寬。
原因是連續(xù)英文段為一個整體導致的，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，這個屬性是通用的對于頑固的南換行問題都可以解決，不局限于GridView。

?12.GridView顯示隱藏某一列：
本方案為月兒獨創(chuàng)，不同于網(wǎng)上其他方式，我覺得用一個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[] { "身份證號碼" };
??????? GridView1.DataBind();
??????? sqlcon.Close();
??????? GridView1.Columns[3].Visible = false;//一開始隱藏
??????? CheckBox1.Checked = false;//如果不這樣后面的代碼會把他True
??? }

雙擊CheckBox1，在CheckedChanged方法里寫上代碼，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！

?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="身份證號碼" 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！

??????????????????????? <FooterStyle BackColor="White" ForeColor="#000066" />
??????????????????????? <Columns>
??????????????????????????? <asp:BoundField DataField="身份證號碼" HeaderText="編號" ReadOnly="True" />
??????????????????????????? <asp:BoundField DataField="郵政編碼" HeaderText="郵政編碼" SortExpression="郵政編碼" />

??????????????????????? </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(shè)如上的樣式，HeaderStyle加CssClass="Freezing，套住GridView的Div設(shè)置高度寬度 <div style="overflow-y: scroll; height: 200px;width:200px" >

16.GridView突出顯示某一單元格（例如金額低于多少，分數(shù)不及格等）

效果圖：

解決方案：主要是綁定后過濾
?GridView1.DataBind();

??????? {
??????????? DataRowView mydrv = myds.Tables["飛狐工作室"].DefaultView[i];

??????????? if (Convert.ToDouble(score) < 34297.00)//大家這里根據(jù)具體情況設(shè)置可能ToInt32等等
??????????? {

?18.GridView數(shù)據(jù)導入Excel/Excel數(shù)據(jù)讀入GridView

效果圖：

解決方案：
頁面增加一個按鈕，單擊事件添加如下方法：
protected void Button1_Click(object sender, EventArgs e)
??? {
??????? Export("application/ms-excel", "學生成績報表.xls");
??? }

??? private void Export(string FileType, string FileName)
??? {
??????? Response.Charset = "GB2312";
??????? Response.ContentEncoding = System.Text.Encoding.UTF7;
??????? Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
??????? Response.ContentType = FileType;
??????? this.EnableViewState = false;
??????? StringWriter tw = new StringWriter();
??????? HtmlTextWriter hw = new HtmlTextWriter(tw);
??????? GridView1.RenderControl(hw);
??????? Response.Write(tw.ToString());
??????? Response.End();
??? }
//如果沒有下面方法會報錯類型“GridView”的控件“GridView1”必須放在具有 runat=server 的窗體標記內(nèi)
??? public override void VerifyRenderingInServerForm(Control control)
??? {
??? }

讀取Excel數(shù)據(jù)的代碼：這個很簡單的
private DataSet CreateDataSource()
??? {
??????? string strCon;
??????? strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("excel.xls") + "; Extended Properties=Excel 8.0;";
??????? OleDbConnection olecon = new OleDbConnection(strCon);
??????? OleDbDataAdapter myda = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strCon);
??????? DataSet myds = new DataSet();
??????? myda.Fill(myds);
??????? return myds;
??? }
??? protected void Button1_Click(object sender, EventArgs e)
??? {
??????? GridView1.DataSource = CreateDataSource();
??????? GridView1.DataBind();
??? }

由于時間關(guān)系，這個文章先到此。有時間再寫，其實還有很多技巧，不過我覺得如果能融匯貫通應該可以舉一反三。
