WPF 水平数据网格

Question

我想要一个水平方向的 WPF DataGrid，有人知道解决方案吗？

Answer 1

我之前已经这样做了，因为我们希望能够对 DataGrid 使用相同的控件。和一个 PropertyGrid .许多事情必须改变(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，但这应该可以帮助您入门。这是自动生成的 TextColumns 的示例，但您可以轻松修改它以使用其他列类型。

<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 Columns 生成时，我们反转它们的位置并旋转 TextBlocks 和 TextBoxes(这比旋转 DataGridCell 在对齐、模糊等方面更好)

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);
    }
}
