I am attempting to create a grid in Xamarin forms with two columns that each take up half of the screen. I have implemented my XAML as follows
<Grid VerticalOptions="End" HorizontalOptions="CenterAndExpand" BackgroundColor="#3F4045" Margin="0,0,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="5*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Rectangle Grid.Row="0" Grid.ColumnSpan="2" VerticalOptions="Center" HorizontalOptions="CenterAndExpand" BackgroundColor="#3F4045"/>
<Grid Grid.Row="1">
<Grid Grid.Column="0" HorizontalOptions="Start">
<Frame BackgroundColor="#FCFCFC" CornerRadius="0" Margin="0" Padding="0">
<Entry TextColor="#3F4045" BackgroundColor="#FCFCFC" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand" PlaceholderColor="#3F4045" Placeholder="Last Name, First Name"/>
</Frame>
</Grid>
<Grid Grid.Column="1" HorizontalOptions="Start">
<Frame BackgroundColor="#FCFCFC" CornerRadius="0" Margin="0" Padding="0">
<Button TextColor="#3F4045" BackgroundColor="#FCFCFC" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand" Text="Upload Records"/>
</Frame>
</Grid>
</Grid>
</Grid>
The two frames are supposed to each take up half of the second row with a small amount of space between them. However, when the app loads, they each take up half of the first column with a small amount of space between them. I experimented by changing the width of the second column from 5* to 8* and, as I expected, both of the frames shrunk so together they took up 5/13 of the screen, meaning that they are actually both in the first column. Here are pictures of the problem and the test I did with widths 5* and 8* for reference:
Is there something I'm missing in setting Horizontal/VerticalOptions in the frames or grid tags? Thank you for the help!
The solution was removing the frames from the Grid tags and making them children of the parent grid directly, using Grid.Row and Grid.Column to assign them to the proper locations.
<Grid VerticalOptions="End" HorizontalOptions="CenterAndExpand" BackgroundColor="#3F4045" Margin="0,0,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="5*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Rectangle Grid.Row="0" Grid.ColumnSpan="2" VerticalOptions="Center" HorizontalOptions="CenterAndExpand" BackgroundColor="#3F4045"/>
<Frame Grid.Row="1" Grid.Column="0" BackgroundColor="#FCFCFC" CornerRadius="0" Margin="0" Padding="0">
<Entry TextColor="#3F4045" BackgroundColor="#FCFCFC" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand" PlaceholderColor="#3F4045" Placeholder="Last Name, First Name"/>
</Frame>
<Frame Grid.Row="1" Grid.Column="1" BackgroundColor="#FCFCFC" CornerRadius="0" Margin="0" Padding="0">
<Button TextColor="#3F4045" BackgroundColor="#FCFCFC" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand" Text="Upload Records"/>
</Frame>
</Grid>
Here is the updated code.
I want to make a UI like this:
This UI should correspond to different phone screen sizes.
I started to write this XAML code:
<StackLayout>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Frame BackgroundColor="Transparent"/>
</Grid>
<Grid Margin="20">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10"/>
</Grid>
<Grid Grid.Row="1" Padding="0,40,0,0">
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10"/>
</Grid>
</Grid>
<Entry Grid.Row="0" Grid.Column="1" MaxLength="30" Placeholder="User Name:" ClearButtonVisibility="WhileEditing"/>
<Entry Grid.Row="1" Grid.Column="1" MaxLength="30" Placeholder="Password:" ClearButtonVisibility="WhileEditing" IsPassword="True"/>
<Image Source="User.png" Scale="0.6"/>
<Image Source="Lock.png" Scale="0.6"/>
<Button Text="Login"/>
</StackLayout>
I know that Those images must be in the Grid node above. But I cannot set those Entry and user/pass logos correctly. Those buttons are images in the resource folder.
Please help me to set a UI similar to this image.
One grid is enough, you can remove one.
You can refer to the following code:
<StackLayout BackgroundColor="#1E90FF" Orientation="Vertical">
<Grid Margin="20" >
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10" Grid.Row="0" Grid.ColumnSpan="2" />
<Entry Grid.Row="0" Grid.Column="0" MaxLength="30" Placeholder="User Name:" ClearButtonVisibility="WhileEditing" />
<Image Source="head.png" Scale="0.6" Grid.Row="0" Grid.Column="1"/>
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10" Grid.Row="1" Grid.ColumnSpan="2"/>
<Entry Grid.Row="1" Grid.Column="0" MaxLength="30" Placeholder="Password:" ClearButtonVisibility="WhileEditing" IsPassword="True"/>
<Image Source="Lock.png" Scale="0.6" Grid.Row="1" Grid.Column="1"/>
</Grid>
<Button Text="Login"/>
</StackLayout>
The result is:
I have a Grid with two rows in Auto within a CollectionView. In one I have a FlexLayout, in the other a Label. For some strange problem, with these two controls the Label is not displayed and the only way I have found so far is to replace the FlexLayout with a StackLayout.
<DataTemplate>
<yummy:PancakeView CornerRadius="15">

</DataTemplate>
</BindableLayout.ItemTemplate>
</FlexLayout>
<Label Grid.Row="3" Grid.Column="1" FontFamily="FontM" TextColor="{DynamicResource TextColor}" FontSize="16" Text="{Binding Nota}"/>
Result
Is there any way to turn this FlexLayout into a StackLayout and be able to visualize in the same way?
Use * instead of Auto for your FlexLayout row.
<Grid BackgroundColor="{DynamicResource SfondoElemDiario}" RowSpacing="0.2">
<Grid.RowDefinitions>
<RowDefinition Height="27" />
<RowDefinition Height="27" />
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<!-- elements -->
</Grid>
I have a problem. I am trying to achieve the following Grid:
To do that, I thought that I should set both the ColumnWidth to Auto and set the HorizontalOptions of the Grid to Center, so the Grid is centred in the middle of the screen creating equal spaces at the left and right side, but no matter what I try, I can't seem to move the columns from the right side. Here is what I have now:
And here is my code:
<Frame BorderColor="#00D8FF" Padding="0" HorizontalOptions="FillAndExpand" BackgroundColor="Transparent">
<StackLayout Orientation="Vertical">
<CarouselView ItemsSource="{Binding coinDataList}" HeightRequest="50">
<CarouselView.ItemTemplate>
<DataTemplate>
<Grid RowSpacing="0" HorizontalOptions="Center">
<Grid.RowDefinitions>
<RowDefinition Height="25" />
<RowDefinition Height="25" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="1" Text="BTC-USDT" FontAttributes="Bold" TextColor="#00D8FF" FontSize="18"/>
<Label Grid.Row="1" Grid.Column="1" Text="9762.33" TextColor="White" FontSize="18"/>
<Label Grid.RowSpan="2" Grid.Column="2" Text="-$476.22 (-4.77%)" VerticalOptions="CenterAndExpand" FontAttributes="Bold" TextColor="Red" FontSize="18" Margin="15,0,0,0"/>
</Grid>
</DataTemplate>
</CarouselView.ItemTemplate>
</CarouselView>
</StackLayout>
</Frame>
How can I create my wanted result?
Can you try this?

the previous code generate the next screen but is height is a lot bigger than the height of the tablet emulator and I don't know why.
The only way that I solved it was declaring the grid with fix height, but even when the window is big and I checked its height value, turns out to be small. Thank you for your help
You can put your scroll view into absolute layout and set bounds and flags - it should work
