I have a Xamarin Forms project and I have a Content Page with a ListView in which I have two buttons to add or remove items from a Cart.
When I click on the remove button it works just fine but when I click on the add button it only works if I click it on the left corner. If I click somewhere else on the button it will register as if I click the entire item on the listView.
Also, I don't know why but the buttons change its size when clicked.
Here is how it is performing
And here is the code. The button that is not working properly is called btnAdd

Please help because I have no idea of why this is happening. Thanks.
EDIT
If I remove the label in between the two buttons it will work, don't know why
You may get more reliable behavior if you:
Add the missing RowDefinition, so Grid.Row="3" has height 35.
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
<!-- ADD BELOW LINE -->
<RowDefinition Height="auto"/>
<RowDefinition Height="35"/>
</Grid.RowDefinitions>```
Remove the unneeded StackLayout. Change:
<StackLayout Grid.Column="0" Grid.Row="3" HorizontalOptions="StartAndExpand">
<Grid>
...
</Grid>
</StackLayout>
to:
<Grid Grid.Column="0" Grid.Row="3" HorizontalOptions="StartAndExpand">
...
</Grid>
IF the above are not sufficient, you might need to add a HeightRequest or hardcoded RowDefinition Height somewhere. I realize this is not ideal - Auto heights are preferable, because they adapt as needed - but sometimes Xamarin Forms needs that extra hint.
The first place to try is to give the whole ItemTemplate a HeightRequest:
<ViewCell>
<Frame ... HeightRequest="300" ...
If that works, then you might try instead putting that on one of the nested elements, to allow most of the content to be automatically sized.
ALTERNATIVE (If the first two items aren't enough)
Its possible to collapse any complex ItemTemplate layout to a SINGLE Grid. Then use StackLayout within cells as needed (but NO NESTED Grids). This is done by use of ColumnSpan and RowSpan to describe areas of the overall grid. You can see this visually if you DIAGRAM the entire layout on a piece of paper, drawing vertical and horizontal lines around each section. Extend those lines all the way to edges of the outer grid.
Xamarin Forms should do a better job of figuring out the layout of this single Grid.
The page might also appear faster.
Try to change the order of the Label , like this .
<Button
x:Name="btnRemove"
Grid.Column="0"
Padding="0"
BackgroundColor="#E5D3C2"
BorderColor="#353A47"
BorderWidth="0.3"
Clicked="BtnRemove_Clicked"
CommandParameter="{Binding .}"
CornerRadius="15"
HeightRequest="35"
Text="-"
TextColor="#353A47"
WidthRequest="50" />
<Label
x:Name="lblQuantity"
Grid.Column="1"
FontAttributes="Bold"
FontSize="15"
HeightRequest="20"
HorizontalTextAlignment="Center"
Text="{Binding Quantity}"
VerticalOptions="Center"
VerticalTextAlignment="Center"
WidthRequest="30" />
<Button
x:Name="btnAdd"
Grid.Column="2"
Padding="0"
BackgroundColor="#E5D3C2"
BorderColor="#353A47"
BorderWidth="0.3"
Clicked="BtnAdd_Clicked"
CommandParameter="{Binding .}"
CornerRadius="15"
HeightRequest="35"
Text="+"
TextColor="#353A47"
WidthRequest="50" />
I did a test based on your code,I found that the middle Label lblQuantity(Label x:Name="lblQuantity") has covered button (Button x:Name="btnAdd" ), so you can just remove property WidthRequest="30" of the middle label (lblQuantity), just as follows:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<Button x:Name="btnRemove"
Grid.Column="0"
CornerRadius="15"
BackgroundColor="#E5D3C2"
WidthRequest="50"
HeightRequest="35"
Padding="0"
Text="-"
Clicked="btnRemove_Clicked"
BorderWidth="0.3"
TextColor="#353A47"
BorderColor="#353A47"/>
<Button x:Name="btnAdd"
Grid.Column="2"
CornerRadius="15"
BackgroundColor="#E5D3C2"
WidthRequest="50"
HeightRequest="35"
Padding="0"
Text="+"
Clicked="btnAdd_Clicked"
BorderWidth="0.3"
TextColor="#353A47"
BorderColor="#353A47"/>
<Label x:Name="lblQuantity"
Grid.Column="1"
VerticalOptions="Center"
Text="{Binding Name}"
FontAttributes="Bold"
FontSize="15"
HorizontalTextAlignment="Center"
VerticalTextAlignment="Center"
HeightRequest="20"

An item template that includes a SkiaSharp control displaying svg, a SwipeView and some labels,
is taking forever to load when navigating to the page.
I am using StackLayout with BindableLayout.ItemSource and ItemTemplate.
Using CollectionView will let the page load much faster, but then every attempt to scroll down will slow the app for a moment, while the CollectionView generate the next batch of items.
I have moved all the code generating the items source to background, so the only thing happening on the ui thread is the binding to the ObservableCollection from the viewmodel, and drawing it.
I have also tried reducing the layouts in the item template, but it did not improve loading speed.

For comparison, replacing the item template with a simple Label makes the page load extremely fast.
Is there a way to load lists of items faster in Xamarin Forms?
Too many StackLayouts. Even worse, you stacked them into each other. Don't do that.
StackLayouts need a lot of layout cycles, as they have to calculate their size based on the children you have put in. If one of those children is a StackLayout as well, that will more than double the layout passes necessary to get to the final result.
And now guess what happens, when you have 50 or more items in your list. Those layout passes will have to run for each single item in your list.
My advice based on my experience would be to replace the StackLayouts with a grid and place your elements using their Grid.Row, Grid.Colum, Grid.RowSpan and Grid.Columnspan properties. Also set your grid sizes to either fixed values or use star based sizes. Don't use "Auto" as this needs more layout passes as well.
I have a TableView containing a number of ViewCells. Each ViewCell is a StackLayout of a Label and Entry field. Everything looks fine rendering on Android. On iOS, any ViewCell that has an field has the Field Value cutoff (ie. shows only the first character then a few dots). Pickers work just fine BTW.
I've tried different MinimumWidthRequest to a high value, the different HorizontalOptions, ForceLayout() in OnAppearing(), etc..
How can I have these fields expand to the necessary minimums, to show the full value?
<TableView>
<TableSection x:Name="tblSingleCourse">
<ViewCell IsEnabled="True">
<StackLayout Orientation="Horizontal" HorizontalOptions="Center">
<Label Text="Course Name:" />
<Entry x:Name="txtCourseTitle" HorizontalOptions="Center"/>
</StackLayout>
</ViewCell>
<ViewCell IsEnabled="True">
<StackLayout Orientation="Horizontal" HorizontalOptions="Center">
<Label Text="Start Date:" />
<DatePicker x:Name="dpStartDate" Format="D"></DatePicker>
</StackLayout>

Just as a suggestion, considering that we are talking about Xamarin Forms it's better to explain if you have this issue just on Android, iOS or both (or UWP in case).
Anyway, I think that at the following link you can find all the help that you need
https://xamarinhelp.com/accommodate-on-screen-keyboard-xamarin-forms/
Let me know if it solve your problems. In case it won't solve your problem I think it is better if you explain the problem in a more detailed way.
I have Xamarin page which has a grid with two rows and a column. In the first row/column I have a label and the second row/column I have a frame where it does not take the full height of the row. Could you help, please?

There is default spacing in Row and Column .
Grid has properties to control spacing between rows and columns. The following properties are available for customizing the Grid:
ColumnSpacing – the amount of space between columns. The default value of this property is 6.
RowSpacing – the amount of space between rows. The default value of this property is 6.
Here you can set RowSpacing= "0" to get full height of the row.
<Grid BackgroundColor="Accent" RowSpacing="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="330"/>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Label BackgroundColor="Wheat" Grid.Column="0"

<Frame

BackgroundColor="White"
HasShadow="True"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand"
Margin="12,0,12,0" />
</Grid>
By the way Margin="12,20,12,0" also can affect the top space, if not necessary ,can set this : Margin="12,0,12,0"
Works fine with frames ?
