數據綁定在gridview中使用

checkbox不能直接在gridview中應用,他的值是0或1才能綁定datefiled字段，否則需用模板字段

<asp:CheckBox ID="CheckBox1" runat="server" Text='<%# eval("in_id") %>' /> 得原值
<asp:CheckBox ID="CheckBox1" runat="server" Text='<%# eval("in_id","[{0}]") %>' /> 值的兩邊加[]

格式字符串結果
{0:d}     YY-MM-DD
{0:p}     百分比00.00%
{0:N2} 12.68
{0:N0} 13
{0:c2}    $12.68
{0:d}      3/23/2003
{0:T}     12:00:00 AM
{0:男;;女}

格式字符串資料結果
"{0:C}" 12345.6789 -> $12,345.68
"{0:C}" -12345.6789 -> ($12,345.68)

{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

格式字符串
1、常用的數值格式字符串：

3、數字的圖片格式字符
0 沒有有效值則顯示0
# 數字佔位符
. 小數點
, 分隔符
% 百分比
E+0,E-0,e+0或e-0 將輸出格式爲科學或指數含義
/ 轉義字符
"或' 它們之間的任何字符都被解釋爲字符串
{和} 用於顯示單文字性花括號，如"{{"顯示爲"{"
；分隔格式字符串中正、負和零值的兩個或三個部分

今天看到一篇關於GridView使用的文章感覺很好，特來分享，關於向服務器添加事件
1、刪除前加判斷
protected void gv_productJingPing_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
         e.Row.Cells[4].Attributes.Add(" "javascript:return confirm('您真的要刪除["+e.Row.Cells[1].Text+"]嗎？')");
    }
}

2、編輯時控制文本框的寬度
protected void gv_productJingPing_RowDataBound(object sender, GridViewRowEventArgs e)
{
     if(e.Row.RowType == DataControlRowType.DataRow)
     {
          if ((e.Row.RowState & DataControlRowState.Edit) != 0)
          {
               TextBox txtUrl = (TextBox)e.Row.Cells[2].Controls[0];
               txtUrl.Width = 230;
          }
      }
}
(說明:如果使用模板列,則可自定義列長)

3、顯示圖片
<asp:ImageField DataImageUrlField="imagepath" DataImageUrlFormatString="img/{0}">
</asp:ImageField>
說明：imagepath指的是數據庫圖片字段名，img指圖片存放位置

4 、 GridView的雙擊/單擊/鍵盤按鍵/鼠標懸浮/移出等事件
<script language="javascript">
         function DbClickEvent(d)
         {
               window.alert("事件類型: DoubleClidk   作用對象: " + d);
         }
         function ClickEvent(d)
         {
               window.alert("事件類型: OnClick   作用對象: " + d);
         }
         function GridViewItemKeyDownEvent(d)
         {
               window.alert("事件類型: GridViewItemKeyDownEvent   作用對象: " + d);
         }
</script>
          (綁定事件)
if( e.Row.RowType == DataControlRowType.DataRow)
{
          //鼠標移動到每項時顏色交替效果
          e.Row.Attributes.Add ("OnMouseOut",   "this.style.backgroundColor='White';this.style.color='#003399'");
          e.Row.Attributes.Add("OnMouseOver", "this.style.backgroundColor='#6699FF';this.style.color='#8C4510'");
          //單擊/雙擊事件
          e.Row.Attributes.Add("OnDblClick", "DbClickEvent('" + e.Row.Cells[1].Text + "')");
          e.Row.Attributes.Add("OnClick", "ClickEvent('" + e.Row.Cells[1].Text + "')");
          e.Row.Attributes.Add("OnKeyDown", "GridViewItemKeyDownEvent('" + e.Row.Cells[1].Text + "')");
          //設置懸浮鼠標指針形狀爲"小手"
          e.Row.Attributes["style"] = "Cursor:hand";

}

5、將GridView的列的Visible設置爲false時,該列無法更新到數據庫

優化性能
SqlConnection con = new SqlConnection();
conn.ConnectionString = "server=(local);dataset=mydb;uid=sa;pwd=xxx";
SqlCommand cmd = new SqlCommand("select name1,name2 from name where id=1", conn);
conn.Open();
SqlDataReader dtr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
dtr.read();
Text1.text=dtr["name1"].ToString();
Text2.text=dtr["name2"].ToString();

雙擊GridView的OnRowDataBound事件；
在後臺的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?')");
}
}

}

WebConfig加密

數據庫的連接字符串標準都是放到web.config裏，因爲有API可以直接訪問並取出數據，這樣實際上非

常不安全,都是以明文形式顯示的,如果WEB服務器被黑客或木馬將其WebConfig配置文件獲取,那數據庫

將是一場災難.加密的方式有很多種,但過於繁瑣就顯得很不方便,.NET 裏有ASP.NET IIS 註冊工具

(Aspnet_regiis.exe) 這樣的一個工具，可以對站點的.config文件的節進行加密
方法：

加密：aspnet_regiis -pef "加密的web.config裏面的配置節名稱" "web.config文件所處的目錄"
解密：aspnet_regiis -pdf "加密的web.config裏面的配置節名稱" "web.config文件所處的目錄"

aspnet_regiis -pef "connectionStrings" "d:/introor/wwwroot/cp"

加密之前:
<connectionStrings>
<add name="pubsConnectionString" connectionString="Data Source=MHL/SQL2000;Initial

Catalog=pubs;User ID=sa;Password=sql2000"
   providerName="System.Data.SqlClient" />
</connectionStrings>
加密之後:
    <connectionStrings configProtectionProvider="RsaProtectedConfigurationProvider">
<EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"

加密碼後出在iis配置時出現

配置錯誤：未能使用提供程序“RsaProtectedConfigurationProvider”進行解密。提供程序返回錯誤信息爲: 打不開 RSA 密鑰容器。
源文件: C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/Config/web.config。

通過如下解決

aspnet_regiis -pa "NetFrameworkConfigurationKey" "NT AUTHORITY/NETWORK SERVICE"

文件的源文件中要引用code中的變量時，要把變量public

public user_code as string

然後在頁面中就可以用啦<%=user_code%>

Asp.Net 2.0 中實現了IButtonControl接口的控件都有一個PostBackUrl屬性，可以進行跨頁面提交，就是用的POST方法。那麼在1.x中費了一番周折的POST提交就很簡單了，只要把PostBackUrl設置爲提交頁，在那提交頁用Request.Params[]就能拿到POST的表單參數了。還能用PreviousPage.FindControl去取前一頁的控件。這裏用Request和PreviousPage去取值都和Server.Transfer很象，但CrossPagePo

asp.net調用javascrpt

中不知道爲什麼不能放在.js中,需要考到.net項目中走一下

頁面的一些變量可以放在viewstate("a")中

在gridview中的 select deleltelinkbutton 之間有一個空間，用於空格，如果選取delete 得使用e.row.cells(0).controls(2)來使用他

datalist中的使用綁定

        <asp:DataList ID="DataList1" runat="server" Font-Names="宋體">
            <ItemTemplate>
<table border="1" cellpadding="0" cellspacing="0" width="800px" bordercolorlight="#D9D9D9" bordercolordark="#FFFFFF">
<tr>
  <td height="22" bgcolor="#E8EEED">
  <p align="center">
            <asp:Label ID="Label1" runat="server" Text="<%# bind('title') %>" Font-Bold=true></asp:Label>
            　<asp:Label ID="Label2" runat="server" Text="<%# bind('adate') %>"></asp:Label>
        </td>
</tr>
<tr>
  <td valign="top">
  <p style="line-height: 150%">
            <br />
            <asp:Label ID="Label3" runat="server"><%#zhgs(Eval("content").ToString())%></asp:Label>
            　<br /><br />
        </td>
</tr>
</table>
            </ItemTemplate>
        </asp:DataList>

使用stateserver中使用session，可以用usecookies模式，不用inurl模式

在asp.net中顯示安全的錯誤信息，可以把 debut=false;
1.<compilation debug="false" strict="false" explicit="true">
2.<customErrors mode="RemoteOnly"/>

全局函數放在web.config 中

</appSettings>

調用

Response.Write(ConfigurationManager.AppSettings("Config").ToString())

直接選列名

   Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then

            dr = e.Row.DataItem

string error = ee.Message.Replace("'", " ");

return false;
}

遍歷頁面中textbox

        Dim i As Integer
        For i = 1 To 3
            Dim t As TextBox
            t = Page.FindControl("textbox" & i)
            Response.Write(t.Text)
        Next

自動選取客戶資源文件,

把頁面的uiculcure 設爲auto,系統爲根據客戶端語言選項,也可以在web.config中設置

新建一個global_resuoure文件夾

然後建立Resource.en.resx,Resource.resx 兩個文件把其中string1改爲path 值爲路徑 en.的path改爲address

在程序中直接調用

Button1.Text = Resources.Resource.path

<asp:TextBox ID="TextBox1" runat="server"
Text="<%$ Resources:resource, path %>"></asp:TextBox>

局部資源文件是local_

在站點中建立局部資源文件的時候，VS.Net2005會自動建立一個App_LocalResources文件夾專門來存放局部資源文件。所謂局部資源文件，也就是給站點中單一頁面文件使用的資源文件。它的命名方式一般是Default.aspx.resx和Default.aspx.zh-cn.resx。現在我在Default資源文件中添加三個鍵Language、lblNavigation.Text和lblNavigation.ForeColor。其中我爲Default.aspx.resx的lblNavigation.ForeColor設置blue，爲Default.aspx.zh-cn.resx的lblNavigation.ForeColor設置red。在頁面文件中Default.aspx中從局部資源文件裏獲得內容的方法如下有兩種：
(1). <asp:Label ID="lblLanguage" runat="server" Text="<%$ Resources:Language %>"></asp:Label>
(2). <asp:Label ID="lblNavigaion" runat="server" meta:resourcekey="lblNavigation"></asp:Label>
使用第一種方法時要注意使用符號$。使用第二種方法更加靈活，它可以一次性地爲控件的很多屬性設定值。

如果要編程主加入引用

Imports System.Globalization

7.動態切換語言設置

以上的介紹都是通過IE瀏覽器獲取語言設置，其實我們可以自己設置使用哪種語言。

1)通過在每個頁面裏的Page節指定
<%@ Page Culture="en-us" UICulture="en-us" %>
如上所設，該頁將使用en-us的語言設置。

注意：這只是個概要式寫法，實際的頁面中的Page一般都包含更多的屬性。

2）通過在Web.Config裏的globalization節指定
<system.web>
<globalization culture ="auto" uiCulture ="auto"/>
</system.web>
3）當然還有一種就是通過編程動態切換語言設置啦，這也是實際項目中經常用到的方式

打開Default.aspx，切換到[源]視圖，添加如下代碼
        <a href="?currentculture=zh-cn">中文(中國)</a>
         
        <a href="?currentculture=en-us">English(USA)</a>
打開Default.aspx.cs，添加如下代碼
     String s;

    protected override void InitializeCulture()
     {
         s = Request.QueryString["currentculture"];
        if (!String.IsNullOrEmpty(s))
         {
            //UICulture - 決定了採用哪一種本地化資源，也就是使用哪種語言
            //Culture - 決定各種數據類型是如何組織，如數字與日期
             Thread.CurrentThread.CurrentUICulture = new CultureInfo(s);
             Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(s);
         }
     }
記得添上這個引用
using System.Threading;

多種語言方案

web.config 中設置爲自動
<system.web>
<globalization culture ="auto" uiCulture ="auto"/>
</system.web>

登錄時增加session("lang")的選擇

在頁面中加入preint事件，在其實判斷

    Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit
        Thread.CurrentThread.CurrentUICulture = New CultureInfo("en-us")
        Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("en-us")

Button1.Text = Resources.Resource.path
End Sub

方案2 重寫InitializeCulture(

Protected Overrides Sub InitializeCulture()

Page.UICulture = "zh-cn"

'InitializeCulture()
End Sub

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
         DataRow dr = (DataRow)e.Row.DataItem;
         if(dr["Name"]== "Peter")
         {
               e.Row.Style["backgroundColor"]= "#F7F6F3";
         }

}
}

文本文件寫操作

        Dim sw As StreamWriter
        sw = File.CreateText(Server.MapPath(".") & "/1.html")
        sw.WriteLine("<html><body>hellow</body></html>")
        sw.Close()
        sw.Dispose()
