Grid in Grid not showing Scrollbar in C# WPF

Question

I have a Grid in another Grid and add the second Grid into ScrollViewer but don't see scrollbar for it. The grid i add ScrollViewer has the name InfoGrid. I dont understand why ScrollViewer is not working. Is there any alternative way you can suggest me ? My xaml code for the all window :

                    Content="{lex:LocText Key=clear_killcard, Dict=language, Assembly=FfdcLocalization}"
                    VerticalContentAlignment="Center" MinHeight="30" VerticalAlignment="Center" HorizontalAlignment="Right" Click="ClearKillCardClick"/>
    </Grid>

</Window>

You should move `Grid.Row="3" Grid.Column="1"` to the ScrollViewer instead of declaring it at the inner Grid. — Clemens, Sep 23 '19 at 13:51

The ScrollViewer that you made has no grid.Row set, instead you put it on the grid inside it. That does not make much sense since the grid ("Info Grid") is inside the ScrollViewer so it's parent is the ScrollViewer. You might want to try setting the ScrollViewer row and column.
