电子表格中的标题行

问题描述

我正在使用以下函数将 ASP.NET gridview 导出到 Excel.格式工作得非常好,除了我需要在导出时冻结 Excel 中的标题行.我真的试图避免为此使用第 3 方 Excel 插件,但除非我的 AddExcelStyling 函数中有一些陈旧的 excel 标记.

I'm exporting an ASP.NET gridview to Excel using the following function. The formatting is working really well, except I need to freeze the header row in Excel on the export. I'm really trying to avoid using a 3rd party Excel plugin for this, but unless there's some archaic excel markup in my AddExcelStyling function.

    Public Sub exportGrid(ByVal psFileName As String)

        Response.Clear()
        Response.Buffer = True
        Response.Cache.SetCacheability(HttpCacheability.NoCache)
        Response.ContentType = "application/vnd.ms-excel"
        Response.AddHeader("content-disposition", "attachment;filename=PriceSheet.xls")
        Response.Charset = ""
        Me.EnableViewState = False
        Dim sw As New StringWriter()
        Dim htw As New HtmlTextWriter(sw)
        sfggcPriceSheet.RenderControl(htw)
        Response.Write("<meta http-equiv=Content-Type content=""text/html; charset=utf-8"">" + Environment.NewLine)
        Response.Write(AddExcelStyling())
        Response.Write(sw.ToString())
        Response.Write("</body>")
        Response.Write("</html>")
        Response.End()

    End Sub

还有格式化黑魔法:

   Private Function AddExcelStyling() As String


    Dim sb As StringBuilder = New StringBuilder()
    sb.Append("<html xmlns:o='urn:schemas-microsoft-com:office:office'" + Environment.NewLine + _
    "xmlns:x='urn:schemas-microsoft-com:office:excel'" + Environment.NewLine + _
    "xmlns='http://www.w3.org/TR/REC-html40'>" + Environment.NewLine + _
    "<head>")
    sb.Append("<style>" + Environment.NewLine)

    sb.Append("@page")
    sb.Append("{margin:.25in .25in .25in .25in;" + Environment.NewLine)

    sb.Append("mso-header-margin:.025in;" + Environment.NewLine)
    sb.Append("mso-footer-margin:.025in;" + Environment.NewLine)

    sb.Append("mso-page-orientation:landscape;}" + Environment.NewLine)
    sb.Append("</style>" + Environment.NewLine)

    sb.Append("<!--[if gte mso 9]><xml>" + Environment.NewLine)
    sb.Append("<x:ExcelWorkbook>" + Environment.NewLine)

    sb.Append("<x:ExcelWorksheets>" + Environment.NewLine)
    sb.Append("<x:ExcelWorksheet>" + Environment.NewLine)

    sb.Append("<x:Name>PriceSheets</x:Name>" + Environment.NewLine)
    sb.Append("<x:WorksheetOptions>" + Environment.NewLine)

    sb.Append("<x:Print>" + Environment.NewLine)
    sb.Append("<x:ValidPrinterInfo/>" + Environment.NewLine)

    sb.Append("<x:PaperSizeIndex>9</x:PaperSizeIndex>" + Environment.NewLine)
    sb.Append("<x:HorizontalResolution>600</x:HorizontalResolution" + Environment.NewLine)

    sb.Append("<x:VerticalResolution>600</x:VerticalResolution" + Environment.NewLine)
    sb.Append("</x:Print>" + Environment.NewLine)

    sb.Append("<x:Selected/>" + Environment.NewLine)
    sb.Append("<x:DoNotDisplayGridlines/>" + Environment.NewLine)

    sb.Append("<x:ProtectContents>False</x:ProtectContents>" + Environment.NewLine)
    sb.Append("<x:ProtectObjects>False</x:ProtectObjects>" + Environment.NewLine)

    sb.Append("<x:ProtectScenarios>False</x:ProtectScenarios>" + Environment.NewLine)
    sb.Append("</x:WorksheetOptions>" + Environment.NewLine)

    sb.Append("</x:ExcelWorksheet>" + Environment.NewLine)
    sb.Append("</x:ExcelWorksheets>" + Environment.NewLine)

    sb.Append("<x:WindowHeight>12780</x:WindowHeight>" + Environment.NewLine)
    sb.Append("<x:WindowWidth>19035</x:WindowWidth>" + Environment.NewLine)

    sb.Append("<x:WindowTopX>0</x:WindowTopX>" + Environment.NewLine)
    sb.Append("<x:WindowTopY>15</x:WindowTopY>" + Environment.NewLine)

    sb.Append("<x:ProtectStructure>False</x:ProtectStructure>" + Environment.NewLine)
    sb.Append("<x:ProtectWindows>False</x:ProtectWindows>" + Environment.NewLine)

    sb.Append("</x:ExcelWorkbook>" + Environment.NewLine)
    sb.Append("</xml><![endif]-->" + Environment.NewLine)

    sb.Append("</head>" + Environment.NewLine)
    sb.Append("<body>" + Environment.NewLine)

    Return sb.ToString()

End Function

推荐答案

将 WorksheetOption 元素修改为如下所示:

Modify the WorksheetOption element to something like the following:

<x:WorksheetOptions>
     <x:Selected/>
     <x:FreezePanes/>
     <x:FrozenNoSplit/>
     <x:SplitHorizontal>1</x:SplitHorizontal>
     <x:TopRowBottomPane>1</x:TopRowBottomPane>
     <x:ActivePane>2</x:ActivePane>
     <x:Panes>
      <x:Pane>
       <x:Number>3</x:Number>
      </x:Pane>
      <x:Pane>
       <x:Number>2</x:Number>
      </x:Pane>
     </x:Panes>
     <x:ProtectContents>False</x:ProtectContents>
     <x:ProtectObjects>False</x:ProtectObjects>
     <x:ProtectScenarios>False</x:ProtectScenarios>
    </x:WorksheetOptions>

注意 FreezePanes 元素.我把它从我保存为 HTML 的电子表格中剪下来,第一行被冻结.当这个文件用 Excel 打开时,第一行被冻结.

Notice the FreezePanes element. I cut this out of a spreadsheet that I had saved as HTML with the first row frozen. When this file is opened with Excel, the first row is frozen.

要在每一页上打印标题行,您需要这样的东西:

To have the header row print on each page, you will need something like this:

<x:ExcelName>
  <x:Name>Print_Area</x:Name>
  <x:SheetIndex>1</x:SheetIndex>
  <x:Formula>=Sheet1!$A$2:$F$97</x:Formula>
 </x:ExcelName>
 <x:ExcelName>
  <x:Name>Print_Titles</x:Name>
  <x:SheetIndex>1</x:SheetIndex>
  <x:Formula>=Sheet1!$1:$1</x:Formula>
 </x:ExcelName>

您需要为您的数据动态修改公式中的值.

You will need to modify the values in the formula dynamically for your data.
