我想要一个水平方向的WPF DataGrid,有人知道解决方案吗?

我之前已经这样做了,因为我们希望能够对DataGridPropertyGrid使用相同的控件。很多东西都要改变(比如对齐,滚动,排序箭头的定位等)。有很多代码可以发布整个解决方案,但这应该让你开始。这是使用自动生成的TextColumns的示例,但您可以轻松地将其修改为使用其他列类型。

<ScrollViewer Name="c_dataGridScrollViewer"
              Loaded="c_dataGridScrollViewer_Loaded"
              VerticalScrollBarVisibility="Auto"
              HorizontalScrollBarVisibility="Auto">
    <DataGrid x:Name="c_dataGrid"
              HorizontalAlignment="Left"
              VerticalAlignment="Top"
              AutoGeneratedColumns="c_dataGrid_AutoGeneratedColumns"
              HorizontalScrollBarVisibility="Hidden"
              VerticalScrollBarVisibility="Hidden">
        <DataGrid.ColumnHeaderStyle>
            <Style TargetType="{x:Type DataGridColumnHeader}">
                <Setter Property="LayoutTransform">
                    <Setter.Value>
                        <TransformGroup>
                            <RotateTransform Angle="90"/>
                        </TransformGroup>
                    </Setter.Value>
                </Setter>
            </Style>
        </DataGrid.ColumnHeaderStyle>
        <DataGrid.LayoutTransform>
            <TransformGroup>
                <RotateTransform Angle="-90"/>
            </TransformGroup>
        </DataGrid.LayoutTransform>
    </DataGrid>
</ScrollViewer>

当生成列时,我们反转它们的位置并旋转TextBlocks和TextBoxes(这比在对齐,模糊等方面旋转DataGridCell更好。)

private void c_dataGridScrollViewer_Loaded(object sender, RoutedEventArgs e)
{
    // Add MouseWheel support for the datagrid scrollviewer.
    c_dataGrid.AddHandler(MouseWheelEvent, new RoutedEventHandler(DataGridMouseWheelHorizontal), true);
}

private void DataGridMouseWheelHorizontal(object sender, RoutedEventArgs e)
{
    MouseWheelEventArgs eargs = (MouseWheelEventArgs)e;
    double x = (double)eargs.Delta;
    double y = c_dataGridScrollViewer.VerticalOffset;
    c_dataGridScrollViewer.ScrollToVerticalOffset(y - x);
}

private void c_dataGrid_AutoGeneratedColumns(object sender, EventArgs e)
{
    TransformGroup transformGroup = new TransformGroup();
    transformGroup.Children.Add(new RotateTransform(90));
    foreach (DataGridColumn dataGridColumn in c_dataGrid.Columns)
    {
        if (dataGridColumn is DataGridTextColumn)
        {
            DataGridTextColumn dataGridTextColumn = dataGridColumn as DataGridTextColumn;

            Style style = new Style(dataGridTextColumn.ElementStyle.TargetType, dataGridTextColumn.ElementStyle.BasedOn);
            style.Setters.Add(new Setter(TextBlock.MarginProperty, new Thickness(0, 2, 0, 2)));
            style.Setters.Add(new Setter(TextBlock.LayoutTransformProperty, transformGroup));
            style.Setters.Add(new Setter(TextBlock.HorizontalAlignmentProperty, HorizontalAlignment.Center));

            Style editingStyle = new Style(dataGridTextColumn.EditingElementStyle.TargetType, dataGridTextColumn.EditingElementStyle.BasedOn);
            editingStyle.Setters.Add(new Setter(TextBox.MarginProperty, new Thickness(0, 2, 0, 2)));
            editingStyle.Setters.Add(new Setter(TextBox.LayoutTransformProperty, transformGroup));
            editingStyle.Setters.Add(new Setter(TextBox.HorizontalAlignmentProperty, HorizontalAlignment.Center));

            dataGridTextColumn.ElementStyle = style;
            dataGridTextColumn.EditingElementStyle = editingStyle;
        }
    }
    List<DataGridColumn> dataGridColumns = new List<DataGridColumn>();
    foreach (DataGridColumn dataGridColumn in c_dataGrid.Columns)
    {
        dataGridColumns.Add(dataGridColumn);
    }
    c_dataGrid.Columns.Clear();
    dataGridColumns.Reverse();
    foreach (DataGridColumn dataGridColumn in dataGridColumns)
    {
        c_dataGrid.Columns.Add(dataGridColumn);
    }
}

我真的站在巨人的肩膀上:-)但是,我有一个额外的增强。

@dimaKudr提出了一种转换预定义列而无需代码的方法,并且@FrankE改进了列的顺序。我要添加的是一种使用AutoGenerateColumns="True"模板转换自动生成的列(DataGrid.CellStyle)的方法。所以完整(而且相当优雅)的解决方案是:

<DataGrid ItemsSource="{Binding YourObservableCollection}"
        AutoGenerateColumns="True"
        AutoGeneratingColumn="OnAutoGeneratingColumn">
    <DataGrid.LayoutTransform>
        <TransformGroup>
            <RotateTransform Angle="90"/>
            <MatrixTransform Matrix="-1,0,0,1,0,0"/>
        </TransformGroup>
    </DataGrid.LayoutTransform>
    <DataGrid.ColumnHeaderStyle>
        <Style TargetType="{x:Type DataGridColumnHeader}"
                BasedOn="{StaticResource {x:Type DataGridColumnHeader}}">
            <Setter Property="LayoutTransform">
                <Setter.Value>
                    <TransformGroup>
                        <RotateTransform Angle="-90"/>
                        <ScaleTransform ScaleX="1" ScaleY="-1" />
                    </TransformGroup>
                </Setter.Value>
            </Setter>
        </Style>
    </DataGrid.ColumnHeaderStyle>
    <DataGrid.CellStyle>
        <Style  TargetType="DataGridCell">
            <Setter Property="LayoutTransform">
                <Setter.Value>
                    <TransformGroup>
                        <RotateTransform Angle="-90"/>
                        <ScaleTransform ScaleX="1" ScaleY="-1" />
                    </TransformGroup>
                </Setter.Value>
            </Setter>
        </Style>
    </DataGrid.CellStyle>
</DataGrid>

我简化了以前的解决方案。我不喜欢带有额外scrollviewer的黑魔法,所以我不使用它。但相反,我使用额外的比例转换。

<DataGrid.LayoutTransform>
    <TransformGroup>
        <RotateTransform Angle="-90"/>
        <ScaleTransform ScaleX="1" ScaleY="-1" />
    </TransformGroup>
</DataGrid.LayoutTransform>

<DataGrid.ColumnHeaderStyle>
    <Style TargetType="{x:Type DataGridColumnHeader}"
           BasedOn="{StaticResource {x:Type DataGridColumnHeader}}">
        <Setter Property="LayoutTransform">
            <Setter.Value>
                <TransformGroup>
                    <RotateTransform Angle="-90"/>
                    <ScaleTransform ScaleX="1" ScaleY="-1" />
                </TransformGroup>
            </Setter.Value>
        </Setter>
    </Style>
</DataGrid.ColumnHeaderStyle>

如果是预定义的列列表,则可以直接在XAML中转换单元格内容:

<Style x:Key="TextCellStyle" TargetType="{x:Type TextBlock}">
    <Setter Property="LayoutTransform">
        <Setter.Value>
            <TransformGroup>
                <RotateTransform Angle="-90"/>
                <ScaleTransform ScaleX="1" ScaleY="-1" />
            </TransformGroup>
        </Setter.Value>
    </Setter>
</Style>

这允许您完全逃避代码隐藏。

我发现这种方法非常有用,但我进行了轮换和镜像:

TransformGroup transformGroup = new TransformGroup();
transformGroup.Children.Add(new RotateTransform(90));
transformGroup.Children.Add(new MatrixTransform(-1, 0, 0, 1, 0, 0));

或在Xaml:

<!-- we rotate the whole DataGrid by -90 degree and then mirror via y-Axis so that it is docked vertically to the left side-->
<DataGrid.LayoutTransform>
    <TransformGroup>
        <RotateTransform Angle="90"/>
        <MatrixTransform Matrix="-1,0,0,1,0,0"/>
    </TransformGroup>
</DataGrid.LayoutTransform>

通过使用镜像,我在列表末尾的字段位于底部而不是顶部。

哇,很好的解决方案,谢谢!它还需要修改上/下和左/右按钮之间的行/列选择开关。我试图在 DataGrid 的 keydown 或 keyup 事件中解决这个问题,但这有点奇怪,来回翻转选择。有人有比下面更好的解决方案吗?这只是通过wat向左移动和向右移动的代码原来是行。

private void c_dataGrid_KeyUp(object sender, KeyEventArgs e)
{
    switch (e.Key)
    {
        case Key.Tab:
            if (Keyboard.IsKeyDown(Key.LeftShift))
            {
                if (c_dataGrid.SelectedIndex > 0)
                {
                    c_dataGrid.SelectedIndex--;
                }
            }
            else
            {
                if (c_dataGrid.SelectedIndex < c_dataGrid.Items.Count - 1)
                {
                    c_dataGrid.SelectedIndex++;
                }
            }
            e.Handled = true;
            break;
        }
    }
}
