Is there a way to set auto height for StackLayout in Xamarin?

Hi,
I'm having issue of content being "cut" when I'm using StackLayout (inside of a ScrollView). As my contents are dynamic, some of the contents are long, thus the height of the StackLayout will be extended. However, the issue can be solved by setting the physical height (2000 in my case).

<ScrollView HorizontalOptions="FillAndExpand">
<StackLayout Padding="5" Spacing="5" VerticalOptions="Start" HeightRequest="2000">

However this solution is not "friendly" as for a short content, it will leave a big gap at the bottom.

If you guys have any workaround or a better idea how to do this, it would be greatly appreciated.

You may set -1 instead, it will automatically determine its own height.

HeightRequest="-1"

@David. It doesn't work. By setting the HeightRequest="-1",the StackLayout was "cut" even prematurely, most of the bottom part of the content is cut.

<ScrollView HorizontalOptions="FillAndExpand">
<StackLayout Padding="5" Spacing="5" VerticalOptions="Start" HeightRequest="-1">

Noted. Try make the following changes to resolve your white gap matter:

 <StackLayout Padding="5" Spacing="5" VerticalOptions="StartAndExpand" Orientiation="Vertical">

Open in new window

Note: use "FillAndExpand" for vertificaloptions if you have declared multiple stacklayout setting for ongoing content.

If that not resolve, maybe you have complicated/nested stack layout arrangement.
Otherwise, share more code about your existing XAML settings here.

Hi David,
Here you go my xaml code. I'd also screenshot for you the "cut off" bottom portion (my lblDescription has a long contents)

The bottom is still cutoff using your latest suggestion.

It suppose to be like this (where the last button shown at the bottom).
