Allow full row selection even if clicking on disabled cells in WPF Datagrid

Question

I have a C# WPF Datagrid with some columns disabled (by applying IsEnabled=false style to the DataGridCell), so the cells are grayed and do not allow editing.

I need to allow full row selection on the grid even if the user clicks on that disabled cell ("Descr" in the sample below). Is this possible?

<DataGrid>
    <DataGrid.Columns>
        <DataGridTextColumn Header="Name" Binding="{Binding Name}"/>
        <DataGridTextColumn Header="Descr" Binding="{Binding Descr}">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="IsEnabled" Value="False" />
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>

Answer 1

You could handle the PreviewMouseLeftButtonDown event for the DataGridRow:

<DataGrid x:Name="dg" SelectionUnit="FullRow">
    <DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
            <EventSetter Event="PreviewMouseLeftButtonDown" Handler="dg_PreviewMouseLeftButtonDown" />
        </Style>
    </DataGrid.RowStyle>
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding}" />
        <DataGridTextColumn Binding="{Binding}">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="IsEnabled" Value="False" />
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>

private void dg_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    DataGridRow row = sender as DataGridRow;
    dg.SelectedItem = row.DataContext;
}
