InfoPath 2010：通過以編程方式將行添加到嵌套在重複表中的重複表/節中

Question

我有一個嵌套在重複表中的重複表。嵌套表格包含5列，1年爲1年，4年爲不同季度（財務）。如果項目持續時間超過一年，我需要動態地將行添加到嵌套表中。所以如果項目持續2年，我需要在嵌套表中添加2行並填充數據，如果它持續3年，我需要添加3等。

我看起來不像讓嵌套表填充任何數據。我爲第一個表使用了一個帶有外部XmlWriter的循環，而嵌套表使用了一個嵌套的XmlWriter。這裏是一個代碼示例：

public void BuildHwSwForecastRow(string vendor, string description, string totalCost, XPathNavigator root) 
    { 
     string myNameSpace = NamespaceManager.LookupNamespace("my"); 

     using (XmlWriter writer = root.SelectSingleNode ("/my:myFields/my:HW_SW_Other_Forecast/my:Forecasts",NamespaceManager).AppendChild()) 
     { 
      writer.WriteStartElement("Forecast", myNameSpace); 
      writer.WriteElementString("HSOF-VendorName", myNameSpace, vendor); 
      writer.WriteElementString("HSOF-Description", myNameSpace, description); 
      writer.WriteElementString("HSOF-TotalCost", myNameSpace, totalCost); 

      using (XmlWriter insideWriter = root.SelectSingleNode("//my:HW_SW_Other_Forecast/my:Forecasts/my:Forecast/my:Quarterly_Breakdowns", NamespaceManager).AppendChild()) 
      { 
       insideWriter.WriteStartElement("Quarterly_Breakdown", myNameSpace); 
       insideWriter.WriteElementString("HSOF-Year", myNameSpace, "2011"); 
       insideWriter.WriteElementString("HSOF-Q1", myNameSpace, ""); 
       insideWriter.WriteElementString("HSOF-Q2", myNameSpace, ""); 
       insideWriter.WriteElementString("HSOF-Q3", myNameSpace, ""); 
       insideWriter.WriteElementString("HSOF-Q4", myNameSpace, ""); 
       insideWriter.WriteEndElement(); 
       insideWriter.Close(); 
      } 
      writer.WriteElementString("HSOF-Total", myNameSpace, "0.0"); 
      writer.WriteEndElement(); 
      writer.Close(); 
     } 
    }

試試這個。唯一的區別是，第二個使用塊在第一個使用塊之外。

public void BuildHwSwForecastRow(string vendor, string description, string totalCost, XPathNavigator root) 
{ 
    string myNameSpace = NamespaceManager.LookupNamespace("my"); 

    using (XmlWriter writer = root.SelectSingleNode ("/my:myFields/my:HW_SW_Other_Forecast/my:Forecasts",NamespaceManager).AppendChild()) 
    { 
     writer.WriteStartElement("Forecast", myNameSpace); 
     writer.WriteElementString("HSOF-VendorName", myNameSpace, vendor); 
     writer.WriteElementString("HSOF-Description", myNameSpace, description); 
     writer.WriteElementString("HSOF-TotalCost", myNameSpace, totalCost); 


     writer.WriteElementString("HSOF-Total", myNameSpace, "0.0"); 
     writer.WriteEndElement(); 
     writer.Close(); 
    } 

    using (XmlWriter insideWriter = root.SelectSingleNode("//my:HW_SW_Other_Forecast/my:Forecasts/my:Forecast/my:Quarterly_Breakdowns", NamespaceManager).AppendChild()) 
     { 
      insideWriter.WriteStartElement("Quarterly_Breakdown", myNameSpace); 
      insideWriter.WriteElementString("HSOF-Year", myNameSpace, "2011"); 
      insideWriter.WriteElementString("HSOF-Q1", myNameSpace, ""); 
      insideWriter.WriteElementString("HSOF-Q2", myNameSpace, ""); 
      insideWriter.WriteElementString("HSOF-Q3", myNameSpace, ""); 
      insideWriter.WriteElementString("HSOF-Q4", myNameSpace, ""); 
      insideWriter.WriteEndElement(); 
      insideWriter.Close(); 
     } 
}
