Disable DataGrid current cell border in FullRow selection mode

Question

I am using a DataGrid in row selection mode (i.e., SelectionUnit="FullRow"). I simply want to remove the border that is being placed around the current cell when the user highlights a row in order to have true full row selection (and no cell level selection). I don't mind the notion of the grid maintaining the current cell, I just want to remove that pesky current cell border, perhaps by changing the style of the current cell. What is the easiest way to do this?

Answer 1

You could set the BorderThickness for DataGridCell to 0

<DataGrid ...
          SelectionUnit="FullRow">
    <DataGrid.CellStyle>
        <Style TargetType="DataGridCell">
            <Setter Property="BorderThickness" Value="0"/>
            <!-- Update from comments.
                 Remove the focus indication for the selected cell -->
            <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
        </Style>
    </DataGrid.CellStyle>
    <!-- ... -->
</DataGrid>
