C#のxpsドキュメントで高さの自動を設定できますか? 高さを設定し、内容がそれ以上の場合、空白のページが表示されます。

そのテンプレートの私のコードは以下のとおりです

私のコードは以下のようなものです。

 ReportDocument reportDocument = new ReportDocument();
 StreamReader reader = new StreamReader(new FileStream(@"Template\SalesReport.xaml", FileMode.Open, FileAccess.Read));
 string readerString = reader.ReadToEnd();
 reportDocument.XamlData = readerString;
 reportDocument.XamlImagePath = System.IO.Path.Combine(Environment.CurrentDirectory,                                      @"Templates\");

 reader.Close();
 ReportData reportData = new ReportData();
 DataTable table = new DataTable("Products");
 table.Columns.Add("Code", typeof (string));
 table.Columns.Add("QTY", typeof (int));
 table.Columns.Add("SellPrice", typeof (double));
 List<string> uniqueProductCode = new List<string>();
 for (int i = 1; i <= 5; i++)
 {
table.Rows.Add(new object[]
                   {
                       "Test " + i.ToString(),
                       i,
                       i*52
                   });
uniqueProductCode.Add("gdsfgdsgs");
 }
 reportData.DataTables.Add(table);
 XpsDocument xps =  reportDocument.CreateXpsDocument(reportData);
 DocumentViewer documentViewer = new DocumentViewer();
 documentViewer.Name = "documnetViewer";
 documentViewer.Document = xps.GetFixedDocumentSequence();
 documentViewer.Print();

Sachin、これは私のコードです。ファイルからコンテンツを含むスタック パネルを動的に読み込み、バインディング値を更新し、サイズを計算します。その後、そのページに要素を追加するか、他のページに移動するかを決定します。ここに私のコードサンプル：

    public bool ApplyVisualBlock(FrameworkElement visulaBlock)
    {
        //update binding values
        UpdateAllBindingTargets(visulaBlock);

        _contentContainer.Children.Add(visulaBlock);

        //calculate size
        visulaBlock.Measure(new Size(ContentWidth, ContentHeight));

        double visualBlockHeight = Math.Ceiling(visulaBlock.DesiredSize.Height);
        if ((visualBlockHeight + _currentContentHeight) > ContentHeight)
        {
            //if current cocntent height more than page height go to other page 
            _contentContainer.Children.Remove(visulaBlock);
            return false;
        }
        _currentContentHeight = _currentContentHeight + visualBlockHeight;
        return true;

    }



 public  void UpdateAllBindingTargets( DependencyObject obj)
    {
            FrameworkElement visualBlock = obj as FrameworkElement;
        if (visualBlock==null)
            return;
        if (visualBlock.DataContext==null)
            return;
        Object objDataContext = visualBlock.DataContext;

        IEnumerable<KeyValuePair<DependencyProperty, BindingExpression>> allElementBinding = GetAllBindings(obj);
        foreach (KeyValuePair<DependencyProperty, BindingExpression> bindingInfo in allElementBinding)
        {
            BindingOperations.ClearBinding(obj, bindingInfo.Key);

            Binding myBinding = new Binding(bindingInfo.Value.ParentBinding.Path.Path);
            myBinding.Source = objDataContext;
            visualBlock.SetBinding(bindingInfo.Key, myBinding);
            BindingOperations.GetBindingExpression(visualBlock, bindingInfo.Key).UpdateTarget();
        }
    }

    public  IEnumerable<KeyValuePair<DependencyProperty, BindingExpression>> GetAllBindings( DependencyObject obj)
    {
        var stack = new Stack<DependencyObject>();

        stack.Push(obj);

        while (stack.Count > 0)
        {
            var cur = stack.Pop();
            var lve = cur.GetLocalValueEnumerator();

            while (lve.MoveNext())
                if (BindingOperations.IsDataBound(cur, lve.Current.Property))
                {
                    KeyValuePair<DependencyProperty,BindingExpression> result=new KeyValuePair<DependencyProperty, BindingExpression>(lve.Current.Property,lve.Current.Value as BindingExpression);
                    yield return result;
                }

            int count = VisualTreeHelper.GetChildrenCount(cur);
            for (int i = 0; i < count; ++i)
            {
                var child = VisualTreeHelper.GetChild(cur, i);
                if (child is FrameworkElement)
                    stack.Push(child);
            }
        }
    }
