WPF横向DataGrid

Question

我想有一个水平方向的WPF DataGrid,有没有人知道解决方案？

Answer 1

我之前已经这样做了,因为我们希望能够为a DataGrid和a 使用相同的控件PropertyGrid.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(这比旋转DataGridCell对齐,模糊等更好)

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);
    }
}

Answer 2

我真的站在巨人的肩膀上:-)但是,我有一个额外的增强.

@dimaKudr提出了一种方法来转换预定义的列而不需要代码,并且@FrankE改进了列的顺序.我要添加的是一种AutoGenerateColumns="True"通过使用DataGrid.CellStyle模板转换自动生成的列()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>

Answer 3

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>

在预定义的列列表的情况下,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.
