Linq to XML的動態WPF生成

Question

我一直在嘗試創建一些動態Xaml。

我有下面的C＃

private void LoadUI() 
{ 
    XNamespace xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"; 

    dynamic UI = new XElement(xmlns + "Grid", 
           new XAttribute(XNamespace.Xmlns + "x", "http://schemas.microsoft.com/winfx/2006/xaml"), 
           new XAttribute("Name", "Grid1"), 
           new XElement(xmlns + "Grid.ColumnDefinitions", 
              new XElement(xmlns + "ColumnDefinition", new XAttribute("Width", "100*")), 
              new XElement(xmlns + "ColumnDefinition", new XAttribute("Width", "200*"))), 
           new XElement(xmlns + "StackPanel", new XAttribute("Name", "StackLabels"), 
              new XAttribute("Margin", "3"), 
              from column in this.TableSchema 
              where column.IsPrimaryKey == 0 && column.DataType != "timestamp" 
              select 
               new XElement(xmlns + "Label", new XAttribute("Height", "28"), 
                  new XAttribute("Name", column.ColumnName + "Label"), 
                  new XAttribute("HorizontalContentAlignment", "Right"), 
                  column.ColumnName)), 
           new XElement(xmlns + "StackPanel", 
              new XAttribute("Grid.Column", "1"), 
              new XAttribute("Name", "StackFields"), 
              new XAttribute("Margin", "3") 
            , 

       from column in this.TableSchema 
       where column.IsPrimaryKey == 0 && column.DataType != "timestamp" 
       select 
       GetUIElement(column))); 

    this.DynamicContent.Content = XamlReader.Load(UI.CreateReader()); 

} 

我的錯誤是在試圖創建Grid.Column。確切的錯誤是 { 「明鏡unbekannte會員\」 Grid.Column \ 「卡恩nicht festgelegt werden。」}

所以它不知道Grid.Column ...

任何人任何想法？

它與新的XAttribute（「Grid.Column」，「1」）正常工作，行註釋只是不顯示我想要的自然！

生成網格如下所示：

<Grid xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="Grid1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> 
    <Grid.ColumnDefinitions> 
    <ColumnDefinition Width="100*" /> 
    <ColumnDefinition Width="200*" /> 
    </Grid.ColumnDefinitions> 
    <StackPanel Name="StackLabels" Margin="3"> 
    <Label Height="28" Name="NummerLabel" HorizontalContentAlignment="Right">Nummer</Label>  
    </StackPanel> 
    <StackPanel Grid.Column="1" Name="StackFields" Margin="3"> 
    <TextBox Height="28" Name="txtNummer" Text="{Binding Path=Nummer}" /> 
    </StackPanel> 
    </Grid>

編輯：

這是重複的。看來XamlReader.Load與提供的XmlReader的交互中存在一些問題。它引發XamlParseException 「無法設置未知成員'Grid.Column'。」

字符串轉換和加載XAML從它的工作原理，奇怪的是：

var xml = UI.ToString(); 
var reader = XmlReader.Create(new StringReader(xml)); 
var content = XamlReader.Load(reader); // works now. 

我看到你創建的XML標記只能將其轉換爲UI對象。爲什麼不簡單地從查詢中創建UI對象？
