                                </ListView>
    </Grid>  

I have this code in WPF App.

Problem - scroll never appears. Instead of adding scroll ListView make Height bigger.

The same with ListBox .

When I don't need scroll it looks like and When I need scroll it looks like

---

In what wrapped ListBox : Page > Grid (

<Grid.RowDefinitions>
            <RowDefinition Height="90"  />
            <RowDefinition Height="780" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>

) > Grid ( Grid.RowSpan="3" )> Border > Grid ( <RowDefinition Height="*" /> ) > ListView

Answer 1

You've probably got the grid inside a stack panel or some other control that's unbound in size.

Stack panels grow to what ever size their content needs.

You need to either restrict the maximum size of the stack panel or remove it altogether.

Once you've done that the scrollbar should appear.
