Entry height not working on xamarin forms - xamarin

Question

I want to set the height of the Entries showed on the next peace of code of a Xamarin.Forms project but it just doesn't work..
If I set the height of the row to something like: Height="1.3*", the Entry takes the whole height of the row but the placeholder won't be vertical aligned so I would like to use HieghtRequest instead.
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage BackgroundColor="White">
<Grid BackgroundColor="Transparent" RowSpacing="0" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<Grid.RowDefinitions>
<RowDefinition Height="5*" />
<RowDefinition Height="4*" />
</Grid.RowDefinitions>
<Grid Grid.Row="0" VerticalOptions="FillAndExpand" HorizontalOptions="CenterAndExpand" Padding="0, 30, 0 ,0" RowSpacing="15">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<Entry Grid.Row="0" Placeholder="{Binding emailAddress}" VerticalOptions="Center" HeightRequest="70" WidthRequest="330" BackgroundColor="Gray" TextColor="Black" HorizontalOptions="CenterAndExpand"/>
<Entry Grid.Row="1" Placeholder="{Binding password}" HeightRequest="300" VerticalOptions="Center" WidthRequest="330" IsPassword="true" BackgroundColor="Gray" TextColor="Black" HorizontalOptions="CenterAndExpand"/>
<StackLayout Grid.Row="2">
</StackLayout>
<Button Grid.Row="4" BackgroundColor="Red" TextColor="White" HorizontalOptions="CenterAndExpand" Text="{Binding signIn}" HeightRequest="70" WidthRequest="330"/>
</Grid>
<Grid Grid.Row="1">
</Grid>
</Grid>

Entry Height is not working because you have given 1* as RowDefinition. You can set RowDefinition as Auto and set HeightRequest againt each controls as prefered.
Also Use YAlign="Center" to vertically align the text. I hope this will help
