WPF horizontal DataGrid

Question

I would like to have a WPF DataGrid with a horizontal orientation, does anyone know a solution?

Answer 1

I am truly standing on the shoulders of giants here :-) but, I have an additional enhancement.

@dimaKudr suggested a way to transform predefined columns without code behind, and @FrankE refined the order of the columns. What i am adding is a way to transform, automatically generated columns (AutoGenerateColumns="True"), by using the DataGrid.CellStyle template. So the complete (and quite elegant) solution is:

<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>
