=================================

8.GridView實現刪除時彈出確認對話框：

效果圖：

實現方法：
雙擊GridView的OnRowDataBound事件；
在後台的GridView1_RowDataBound()方法添加代碼，最後代碼如下所示：

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是綁定數據行
        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("onclick", "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；
在後台的GridView1_RowDataBound()方法添加代碼，最後代碼如下所示：
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是綁定數據行 //清清月兒http://blog.csdn.net/21aspnet 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ////鼠標經過時，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();
        }

    }

 

注意這時最好把前台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，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" />

主要是由於htmlencode屬性默認設置為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>
</asp>

前台代碼：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份證號碼"
            DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
            <Columns>
                <asp:BoundField DataField="身份證號碼" HeaderText="身份證號碼" ReadOnly="True" SortExpression="身份證號碼" />
                <asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />
                <asp:BoundField DataField="郵政編碼" HeaderText="郵政編碼" SortExpression="郵政編碼" />
                <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:北風貿易ConnectionString1 %>"
            SelectCommand="SELECT top 5 [出生日期], [起薪], [身份證號碼], [姓名], [家庭住址], [郵政編碼] FROM [飛狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>

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；
{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;
    }

            ////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?')");

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

    }
}

 12.GridView一般換行與強制換行：

效果圖：

首先設置<asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  ItemStyle-Width="100" />
gridview裡有一列綁定的數據很長，顯示的時候在一行裡面顯示，頁面拉得很寬。
原因是連續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();//調用數據綁定即可
        }
    }
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於頑固的南換行問題都可以解決，不局限於GridView。

 13.GridView顯示隱藏某一列：
本方案為月兒獨創，不同於網上其他方式，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;//如果不這樣後面的代碼會把他True
    }

雙擊CheckBox1，在CheckedChanged方法裡寫上代碼，最後代碼如下：
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
    {
         GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;
         Response.Write("GridView1的第4列現在的顯示隱藏狀態是："+GridView1.Columns[3].Visible.ToString());
    }

注意：CheckBox1的AutoPostBack要True！

後台全部代碼如下：

        GridView1.DataBind();
        sqlcon.Close();
        GridView1.Columns[3].Visible = false;
        CheckBox1.Checked = false;
    }

    {
         GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;
         Response.Write("GridView1的第4列現在的顯示隱藏狀態是："+GridView1.Columns[3].Visible.ToString());
    }
}

                    </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>

使用的是結合javascript的window.open方法，關於window.open的參數網上有很多帖子，本站也有許多參考
