WPF DataGrid AutoSize Sayı

Question

Yakın bir zamanda bir WPF (C/4.0) DataGrid içinde çalışan bir metin kaydırma işlemi yapmaya çalışıyorum ve hangi çözümü uyguladığım önemli değil (Tümü, bir şablonun içindeki bir TextBlock biçimi). Kılavuzun otomatik yüksekliği ve ızgaranın alt kısmında aşırı beyaz boşluk (Görünürlük uğruna Sarı olarak ayarla) ile sonuçlanır.

Benim Kod: (Yorumlananlar kod metin kaydırma alternatif çözüm, ama yine de aşırı uzayda sonuçlanır)

<Grid> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="Auto"/> 
     <RowDefinition Height="Auto"/> 
    </Grid.RowDefinitions>

Answer 1

Evet, ben de bir hata olması gerektiğini karşılaştık. Sorun, gerçekten Sarma işleminin kendisi değil, bir hücrenin daha kısa bir sürede küçülmesinden sonra, DataGrid Yüksekliği ne sebepten ötürü yeniden boyutlandırılana kadar (Pencere boyutu ne olursa olsun) güncellenmeyecektir. Bu sorun için iyi bir çözümüm yok, ama burada bir çeşit çözüm var. DataGridColumn Onun yerine TextBlocks kullanarak

Güncelleme

Optimize versiyonu. Sarma Sütunları bilmek için Ekli Özellik WrapColumn (varsayılan olarak false) kullanır.

Xaml. Yerel olarak ekle: MainWindow.WrapColumn = Her kaydırma Sütunu için "Doğru".

<DataGridTemplateColumn Header="Health" 
         local:MainWindow.WrapColumn="True"> 
    <DataGridTemplateColumn.CellTemplate> 
     <DataTemplate> 
      <TextBlock TextTrimming="CharacterEllipsis" 
         TextWrapping="Wrap" 
         Text="{Binding Path=Health}"/> 
     </DataTemplate> 
    </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn> 

ActualWidth gerçek

public MainWindow() 
{ 
    InitializeComponent(); 

    DependencyPropertyDescriptor dependencyPropertyDescriptor = 
     DependencyPropertyDescriptor.FromProperty(DataGridColumn.ActualWidthProperty, typeof(DataGridColumn)); 

    if (dependencyPropertyDescriptor != null) 
    { 
     foreach (DataGridColumn column in c_dataGrid.Columns) 
     { 
      if (GetWrapColumn(column) == true) 
      { 
       dependencyPropertyDescriptor.AddValueChanged(column, DataGridColumn_ActualWidthChanged); 
      } 
     } 
    } 

    void DataGridColumn_ActualWidthChanged(object sender, EventArgs e) 
    { 
     c_dataGrid.Width = c_dataGrid.ActualWidth - 1; 
     EventHandler eventHandler = null; 
     eventHandler = new EventHandler(delegate 
     { 
      c_dataGrid.Width = double.NaN; 
      c_dataGrid.LayoutUpdated -= eventHandler; 
     }); 
     c_dataGrid.LayoutUpdated += eventHandler; 
    } 
    //... 
}

Use this way, to expand your datagrid with proper height and width 
    <my:DataGridTemplateColumn Header="{DynamicResource name}" Width="*" 
                  CanUserSort="True" SortMemberPath="Name" 
                  HeaderStyle="{StaticResource StaffDgColoumnHeaderStyle}"> 
           <my:DataGridTemplateColumn.CellTemplate> 
            <DataTemplate> 
             <TextBlock Style="{StaticResource RowTextblockStyle}" >`enter code here` 
               <Hyperlink> 
                <TextBlock Text="{Binding Path=Name}" ToolTip="{Binding Name}" 
                   TextWrapping="NoWrap" TextTrimming="CharacterEllipsis"/> 
               </Hyperlink> 
              </TextBlock> 
            </DataTemplate> 
           </my:DataGridTemplateColumn.CellTemplate> 
          </my:DataGridTemplateColumn> 

          <my:DataGridTemplateColumn Header="{DynamicResource sft}" Width="*" 
                  CanUserSort="True" SortMemberPath="ShiftName" 
                  HeaderStyle="{StaticResource StaffDgColoumnHeaderStyle}"> 
           <my:DataGridTemplateColumn.CellTemplate> 
            <DataTemplate> 
             <TextBlock Text="{Binding ShiftName}" ToolTip="{Binding ShiftName}" 
                 Style="{StaticResource RowTextblockStyle}"/> 
            </DataTemplate> 
           </my:DataGridTemplateColumn.CellTemplate> 
          </my:DataGridTemplateColumn> 

See Width ="*" Or Use Width ="Auto" or Width = "20*" as per as your requirement.
