Add a CellEditingTemplate. This requires the user to click twice - once to select the cell and again to go into CellEditing mode

            <DataGridTemplateColumn Header="Latest Victory Date" SortMemberPath="LatestVictory">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding LatestVictory, Mode=TwoWay}" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
                <DataGridTemplateColumn.CellEditingTemplate>
                    <DataTemplate>
                        <DatePicker SelectedDate="{Binding LatestVictory, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ConverterCulture='en-GB', StringFormat=d}" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellEditingTemplate>
            </DataGridTemplateColumn>
