Does ScrollViewer need to set MaxHeight or Height in order to work properly?

[IronEaterBeast]

I placed ScrollViewer in a grid, but the grid's height is subject to change based on the size of the entire window. Therefore, I cannot give ScrollViewer an exact height. In this case, how can I use it?

<Grid RowDefinitions="Auto,Auto" Grid.Column="1"> <ScrollViewer Grid.Row="0" MaxHeight="700" AllowAutoHide="False">

Or, is there any other way to use scroll in Grid?

<Grid 
!     RowDefinitions="*,Auto" 
      Grid.Column="1"> 
    <ScrollViewer Grid.Row="0" MaxHeight="700" AllowAutoHide="False">
...
