客戶化FreeTextBox；漢化ImageGallery

1：客戶化FTB的工具列：
AutoGenerateToolbarsFromString="false"
Toolbars/FTB:Toolbar/FTB:ToolbarButton都不可以有id，vs好事，會自動給加上
舉例：
<FTB:FREETEXTBOX language="zh_cn" id="txt_Content" runat="server" AutoGenerateToolbarsFromString="false" Height="400px">
  <Toolbars>
          <FTB:Toolbar runat="server">
           <FTB:ToolbarButton Title="Insert Some Text" ScriptBlock="this.ftb.InsertHtml('FreeTextBox is great!!');" ButtonImage="mybuttonimage" runat="server" />    
          </FTB:Toolbar>
  </Toolbars>         
</FTB:FREETEXTBOX>

2：呼叫指令碼
  ScriptBlock="this.ftb.InsertHtml('FreeTextBox is great!!');"
  可以寫在 <FTB:ToolbarButton 裡面
  可以放在一個類裡面
    public class UploadImg: ToolbarButton
 {
  public UploadImg() : base("UploadImg","FTB_UploadImg","insertimage")
  {}
 }
 
3：在外部調用FTB的函數
  FTB_API[ftbId].InsertHtml(textToInsert);
 
4：在其他頁面調用本地頁面的函數
   a：通過傳遞參數的方式
       首頁：ScriptBlock="this.ftb.InsertHtml(window.showModalDialog('xx.aspx?id=xxx'));"
       子視窗：window.returnValue=xxx; window.close();
   b：直接提供函數調用  
       首頁：提供外部可以調用的js函數
       子視窗：opener.top.Insert2FtbText('','');  window.close();    //調用之

5：漢化ImageGallery

  protected override void Render(HtmlTextWriter writer)
  {
   writer.Write(this.ChineseGallery());
  }
        /// <summary>
        /// 擷取控制項，漢化之
        /// </summary>
        /// <returns></returns>
  private string ChineseGallery()
  {
   StringWriter writer = new StringWriter(); //提供一個可以寫的文本地區
   HtmlTextWriter buffer = new HtmlTextWriter(writer); //讓htmlWriter操作這個地區，我們就可以獲得這個地區裡的內容
   base.Render(buffer); //先讓頁面畫一遍，讓我們得到初始的頁面html代碼
   string html = writer.ToString(); //找到這段代碼，我們來處理它，把英文變成漢字
   //
   html=html.Replace("There are no images:","現在還沒有圖片");
   html=html.Replace("Upload File","上傳圖片");
   html=html.Replace("Status</div>","狀態</div>");
   html=html.Replace("Selected Image","選中的圖片");
   html=html.Replace("Create Folder","建立目錄");
   html=html.Replace("Delete Image","刪除該圖片");
   html=html.Replace("\"Upload\"","'上傳'");
   html=html.Replace("<legend>Preview","<legend>預覽圖片");
   html=html.Replace("<legend>Dimensions","<legend>設定顯示尺寸");
   html=html.Replace("Original Size","原圖大小");
   html=html.Replace("Custom Size","設定為");
   html=html.Replace("Lock image ratio","鎖定尺寸比例");
   html=html.Replace("Percentage","百分比");
   html=html.Replace("Image Gallery","我的像冊");
   html=html.Replace("<legend>Properties","<legend>圖片屬性");
   html=html.Replace("Align","橫向排列");
   html=html.Replace("Border","邊框");
   html=html.Replace("VSpace","左邊距");
   html=html.Replace("HSpace","上邊距");
   html=html.Replace("Alt","轉換文字");
   html=html.Replace("Title","圖片標題");
   html=html.Replace("value=\"Insert\"","value='插入到編輯器中'");
   //
   return html;
  }
