Comment générer des colonnes personnalisées pour FrameworkElementFactory (typeof (Datagrid))?

Question

J'ai DataGrid qui doit avoir childGrid dans RowDetails mais je ne sais pas comment créer des colonnes pour la grille enfant.
Au moment j'ai grille des enfants avec des colonnes générées automatiquement que je ne avez pas besoin:

private static bool CopyWork(TextBox textBox) 
{ 
    try 
    { 
     var match = Regex.Match(textBox.Text, @"^коп раб"); 
     if (match.Success) 
     { 
      var copyWorkWindow = new Window() 
      { 
       Topmost = true, 
       WindowStartupLocation = WindowStartupLocation.CenterScreen, 
       Title = "Копирование документов", 
       SizeToContent = SizeToContent.WidthAndHeight 
      }; 
      var documents = new ObservableCollection<CopyWorkDocument>(); 
      var dataGrid = new DataGrid() 
      { 
       ItemsSource = documents, 
       AutoGenerateColumns = false 
      }; 

      var generateColumn = new Func<string, string, object[], FrameworkElementFactory>((header, bindingItem, items) => 
      { 
       var column = new FrameworkElementFactory(typeof(DataGridTemplateColumn)); 
       column.SetValue(DataGridTemplateColumn.HeaderProperty, header); 

       var binding1 = new Binding(bindingItem) 
       { 
        Mode = BindingMode.TwoWay 
       }; 

       var elementTextBlock = new FrameworkElementFactory(typeof(TextBlock)); 
       elementTextBlock.SetValue(TextBlock.TextProperty, binding1); 
       var cellTemplate = new DataTemplate 
       { 
        VisualTree = elementTextBlock 
       }; 
       column.SetValue(DataGridTemplateColumn.CellTemplateProperty, cellTemplate); 

       if (items != null) 
       { 
        var elementComboBox = new FrameworkElementFactory(typeof(ComboBox)); 
        elementComboBox.SetValue(ComboBox.BackgroundProperty, Brushes.White); 
        elementComboBox.SetValue(ComboBox.ItemsSourceProperty, items); 
        elementComboBox.SetValue(ComboBox.SelectedItemProperty, binding1); 
        var cellEditingTemplate = new DataTemplate 
        { 
         VisualTree = elementComboBox 
        }; 
        column.SetValue(DataGridTemplateColumn.CellEditingTemplateProperty, cellEditingTemplate); 
       } 

       return column; 
      }); 
      dataGrid.Columns.Add(new DataGridTextColumn() { Header = "Название документа", Binding = new Binding("Name") }); 
      dataGrid.Columns.Add(new DataGridTextColumn() { Header = "Количество копий", Binding = new Binding("Documentcount") }); 

      var rowDetailsTemplate = new DataTemplate(); 
      var pagesGrid = new FrameworkElementFactory(typeof(DataGrid)); 
      //pagesGrid.SetValue(DataGrid.AutoGenerateColumnsProperty, false); 
      pagesGrid.SetValue(DataGrid.ItemsSourceProperty, new Binding("Pages")); 
      rowDetailsTemplate.VisualTree = pagesGrid; 
      dataGrid.RowDetailsTemplate = rowDetailsTemplate; 

      copyWorkWindow.Content = dataGrid; 
      copyWorkWindow.ShowDialog(); 
      var sB = new StringBuilder(); 
      foreach (var document in documents) 
      { 
       sB.Append(document).Append(Environment.NewLine); 
      } 
      if (sB.Length > 0) 
      { 
       textBox.Text = sB.ToString(); 
      } 
     } 
     return match.Success; 
    } 
    catch (Exception ex) 
    { 
     ex.LogAndShow(); 
     return false; 
    } 
} 

Il y a columnGenerator ci-dessous.
classe de l'objet:

private class CopyWorkDocument 
{ 
    public string Name { get; set; } 
    public int Documentcount { get; set; } = 1; 
    public List<CopyPage> Pages { get; set; } = new List<CopyPage> { new CopyPage() }; 

    public override string ToString() 
    { 
     var sB = new StringBuilder().Append(Name); 
     foreach (var page in Pages) 
     { 
      sB.Append(Environment.NewLine).Append(Documentcount).Append("шт (").Append(page).Append(")"); 
     } 
     return sB.ToString(); 
    } 

    public class CopyPage 
    { 
     public int Pagecount { get; set; } = 1; 
     public string Pageformat { get; set; } = "A4"; 
     public string Worktype { get; set; } = "печать"; 
     public string Printtype { get; set; } = "односторонняя"; 
     public bool IsColored { get; set; } = false; 

     public static string[] Worktypes { get => new string[] { "печать", "копирование", "сканирование", "брошюровка", "твердый переплет" }; } 
     public static string[] Printtypes { get => new string[] { "односторонняя", "двусторонняя" }; } 
     public static string[] Formats { get => new string[] { "A4", "A3", "A2", "A1" }; } 

     public override string ToString() 
     { 
      var sB = new StringBuilder().Append(Pagecount).Append(" ").Append(Pageformat); 
      if (IsColored) 
      { 
       sB.Append(" цвет"); 
      } 
      return sB.ToString(); 
     } 
    } 
} 

Exemple pour le générateur de Colum:

DataGrid.Columns.Add(generateColumn("ColumnName", "ColumnBinding", "ColumnItemsHelper"[])); 

D'abord je l'ai fait générateur pour DataGrid (Conrol), mais je retravaille pour FrameworkElementFactory (Ce détails inutiles ajoutés en raison de StackOverflow message de codelimitation)

Comme indiqué sur MSDN, l'utilisation de la classe FrameworkElementFactory est un moyen obsolète de créer par programme des modèles: https://msdn.microsoft.com/en-us/library/system.windows.frameworkelementfactory(v=vs.110).aspx.

Vous pouvez utiliser la méthode System.Windows.Markup.XamlReader.Parse à la place:

StringBuilder sb = new StringBuilder(); 
sb.Append("<DataTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" xmlns:x =\"http://schemas.microsoft.com/winfx/2006/xaml\">"); 
sb.Append("<DataGrid ItemsSource=\"{Binding Pages}\" AutoGenerateColumns=\"False\">"); 
sb.Append("<DataGrid.Columns>"); 
//append for each column: 
sb.Append("<DataGridTextColumn Binding=\"{Binding Name}\" Header=\"Name\" />"); 
sb.Append("</DataGrid.Columns>"); 
sb.Append("</DataGrid>"); 
sb.Append("</DataTemplate>"); 
dataGrid.RowDetailsTemplate = XamlReader.Parse(sb.ToString()) as DataTemplate;
