I have the following ListView -
<StackLayout>
<ListView RowHeight="100" Margin="0,10,2,10">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<ViewCell.View>
<StackLayout Orientation="Horizontal" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" Margin="0,4,4,4" Padding="0,4,4,4">
<StackLayout Orientation="Vertical">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Image Grid.Column="0" Source="testLogo" HeightRequest="45" WidthRequest="45"/>
<StackLayout Grid.Column="1" Orientation="Vertical" >
<Label Text="test" Font="Bold" VerticalOptions="Center" />
</StackLayout>
<Button Grid.Column="2" Text="Login" HorizontalOptions="EndAndExpand" Margin="10,10,10,10"/>
</Grid>
</StackLayout>
</StackLayout>
</ViewCell.View>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
This is displaying a columned grid as expected however I cannot float the Button elements to the very right of their respective column.
So currently the display does not look neat in that the buttons position seems to be determined by the string length of the Label elements.
I tried adding VerticalOptions="EndAndExpand" to the Buttons"s however this had no effect.
How can I position the buttons neatly to the far right of their respective columns?
If use Grid as root layout , you can set the width of each Grid item proportionally.
As follow:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="5*" />
<ColumnDefinition Width="3*" />
</Grid.ColumnDefinitions>
The effect:

I'm currently styling a listview, in which I want to add a separating space between each entity in the ListView. For doing that, I use a Grid for each ViewCell with Margin="0,0,0,10".
I can get my elements to fit inside the grid row, but if I add a padding to the row, to give it some top/bottom spacing, it just scales down the text inside the grid.rowuntil eventually, it disappears.
<ListView Margin="10" HasUnevenRows="false" BackgroundColor="Fuchsia" x:Name="deviceList" ItemsSource="{Binding Devices}" CachingStrategy="RecycleElement" SeparatorVisibility="None">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<ViewCell.View>
<Grid BackgroundColor="Silver" Margin="0,0,0,10">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Grid Grid.Row="0" Grid.Column="0" VerticalOptions="Center" RowSpacing="10">
<local:IconView Source="BLE.png" Foreground="#3b5998" WidthRequest="30" HeightRequest="30" />
</Grid>
<Grid Grid.Row="0" Grid.Column="1" VerticalOptions="Center">
<Label Text="{Binding Name}" TextColor="Black" />
</Grid>
</Grid>
</ViewCell.View>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
How do I add padding to my Grid.Row without scaling down the child elements?
I have the following image below which I have tried to design in XAML- Xamarin forms.
The xaml code is as follows:
<ListView x:Name="myList" HasUnevenRows="true" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Frame Padding="0,0,0,8" BackgroundColor="#edeeef" BorderColor="#edeeef">
<Frame.Content>
<Frame OutlineColor="Transparent" BackgroundColor="White">
<Frame.Content>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="7*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="2*" />
</Grid.ColumnDefinitions>
<StackLayout Orientation="Vertical" Grid.Row="0" Grid.Column="0">
<Label Text="{Binding ItemName}"
TextColor="Black"
FontFamily="OpenSans-Light"
FontSize="16"
HorizontalOptions="FillAndExpand"/>
<Label Text="Engine coolant temperature sesnor 1 circuit intermittent (DTC Confirmed)" FontSize="11" HorizontalOptions="StartAndExpand"/>
<StackLayout Orientation="Horizontal">
<Button Text="OBD" />
<Button Text="CUS" />
</StackLayout>
</StackLayout>
<BoxView
VerticalOptions="Fill"
HorizontalOptions="End"
WidthRequest="1"
HeightRequest="5"
Color="Blue"
Grid.Row="0"
Grid.Column="1"/>
<ffsvg:SvgCachedImage
Aspect="AspectFit"
VerticalOptions="Center"
Source="Bin.png"
Grid.Column="2"
Grid.Row="0"
/>
</Grid>
</Frame.Content>
</Frame>
</Frame.Content>
</Frame>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
The issue that I am having is that I am unable to draw the vertical right line separating the content and the square red box on the right.
When I am adding the image, it is adding extra padding on the bottom.
Can someone please help me to align the components properly as in the image above in XamarinForms? Thanks.
Your design is quite messed up and should be cleaned up
Within the ViewCell, you have two nested Frames, which causes the main issue: There is a padding on the inner Frame that and on the outer one, which prevent the separator to take the full height
A nested Grid and StackLayout is most likely not necessary and definitely detrimental for your performance
Suggestions:
Remove the outer Frame and add a Margin to the inner one
Set the Padding of the inner frame to 0
Remove the StackLayout wrapped in the Grid and add the controls to the Grid
Add the Grid.RowSpan and Grid.ColumnSpan for controls that take more height/width in the Grid
Your XAML within the ViewCell will look like this:
<Frame Padding="0"
Margin="5"
BorderColor="Transparent"
BackgroundColor="White"
CornerRadius="10">
<Grid ColumnSpacing="0" RowSpacing="5" Padding="0">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label Text="ItemName"
TextColor="Black"
FontFamily="OpenSans-Light"
FontSize="16"
HorizontalOptions="FillAndExpand"
VerticalOptions="End"
Grid.Column="0"
Grid.Row="0"
Grid.ColumnSpan="2"
Margin="10,10,10,0" />
<Label Grid.Column="0"
Grid.Row="1"
Grid.ColumnSpan="2"
Text="Engine coolant temperature sesnor 1 circuit intermittent (DTC Confirmed)"
FontSize="11"
HorizontalOptions="StartAndExpand"
Margin="10,0,0,0" />
<Button Text="OBD"
VerticalOptions="End"
HorizontalOptions="Start"
Grid.Row="2"
Grid.Column="0"
Margin="10,0,5,10" />
<Button Text="CUS"
VerticalOptions="End"
HorizontalOptions="Start"
Grid.Row="2"
Grid.Column="1"
Margin="0,0,10,10" />
<BoxView VerticalOptions="Fill"
HorizontalOptions="End"
WidthRequest="1"
Color="LightPink"
Margin="0"
Grid.Row="0"
Grid.Column="2"
Grid.RowSpan="3" />
<Image Aspect="AspectFit"
VerticalOptions="Center"
HorizontalOptions="End"
Source="http://lorempixel.com/output/abstract-q-c-200-200.jpg"
Grid.Column="3"
Grid.Row="0"
Grid.RowSpan="3"
Margin="10"/>
</Grid>
</Frame>
And eventually the design looks like that (There is still space for tweaking, but basically that's it. I've changed the colors a bit for better visibility):
Follow this Code.
<Grid Grid.Row="3" Padding="{StaticResource Padding15050}">
<ListView x:Name="ListViewFood" ItemsSource="{Binding FoodList}" HasUnevenRows="True" ItemSelected="OnSelection" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid Padding="{StaticResource Padding510}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="0.5*"/>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Controls:Label x:Name="LabelName" Grid.Row="0" Text = "{Binding Name}" Font="17" TextColor="{StaticResource Black}"/>
<Controls:Label x:Name="LabelDescription" Grid.Row="1" Text = "{Binding Description}" Font="15" />
<Controls:Label x:Name="LabelPrice" Grid.Row="2" Text = "{Binding Price}" Font="15" TextColor="{StaticResource YetiBlue}"/>
</Grid>
<Grid Grid.Column="1">
<Controls:RectangleButton Text="Add" Font="Bold,15" VerticalOptions="Start" HorizontalOptions="EndAndExpand" CommandParameter="{Binding Id}" Clicked="RectangleButton_Clicked"/>
</Grid>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
Design like this.
If you want to add a separate line, you just need to add a BoxView in your xaml with WidthRequest=1.
I always use this solution for separating content.
In your case I would suggest to delete HeightRequest in your BoxView.
So I have this xaml file on my end, what I want is that I want the entry's text not to be behind/overlap with the icon itself.
In order to achieve the icon on the right, I had two columns: One for the entry and one for the icon
I set the Grid.ColumnSpan="2" of the entry and set the icon HorizontalOptions="End" but the text of the entry was behind my icon, how do I prevent this? If more info is needed, do not hesitate to ask me so. Thanks!
EDIT1: Here's the Code
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Entry Grid.Column="0" Grid.ColumnSpan="2" IsPassword="True"/>
<Image Source="eye.png" Grid.Column="1" Grid.ColumnSpan="1"/>
</Grid>
Change your grid width * to Auto
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Entry Grid.Column="0" IsPassword="True"/>
<Image Grid.Column="1" Source="eye.png" WidthRequest="50" HeightRequest="50" />
</Grid>
OR
Try stack layout instead of grid
<StackLayout Orientation="Horizontal" Spacing="0">
<Entry IsPassword="True" HorizontalOptions="FillAndExpand"/>
<Image Source="eye.png" WidthRequest="50" HeightRequest="50"/>
</StackLayout>
Try this:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Entry Grid.Column="0" IsPassword="True"/>
<Image Source="eye.png" Grid.Column="1" />
</Grid>
So here's what I did:
Cross-platform xaml file:
<StackLayout Orientation="Horizontal" Spacing="0">
<Entry HorizontalOptions="FillAndExpand" IsPassword="True"/>
<Image Source="{Binding ImageSource}"
HorizontalOptions="End" Margin="5,0,0,0"
HeightRequest="20"
WidthRequest="20">
<Image.GestureRecognizers>
<TapGestureRecognizer Command="{Binding MaskCommand}"/>
</Image.GestureRecognizers>
</Image>
<StackLayout>
Android Renderer:
Control?.SetBackgroundColor(Android.Graphics.Color.Transparent);
I'll update this after I have tried it on iOS and UWP.
I am facing problem to add Entry inside Grid View Control. I have a list view which will have data with checkbox and entry. If user selects certain item, he can also add quantity of the item in entry. I am facing issue adding entry in grid view. Entry is only displayed half. Text is not displayed correctly. I am adding Entry in xaml as.
<StackLayout>
<Label Text="Items"></Label>
<ListView x:Name="ItemsListView" RowHeight="60">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<ViewCell.View>
<Grid Padding="5,0" RowSpacing="1" ColumnSpacing="1" >
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Label Text="{Binding Title}" Grid.ColumnSpan="2" Grid.Row="1" Margin="2" BackgroundColor="Green"></Label>
<common:CheckBox Grid.Column="3" Grid.Row="1" HeightRequest="20" WidthRequest="20"
VerticalOptions="Center" Checked="{Binding isChecked ,Mode=TwoWay}"
CheckedImage="checkbox_checked" UnCheckedImage="checkbox_unchecked"
CommandParameter="{Binding .}" BackgroundColor="Brown"/>
<Entry Grid.Column="3" Grid.Row="1" IsEnabled="False" Text="CountStr" FontSize="Small" VerticalOptions="End" BackgroundColor="Purple" />
</Grid>
</ViewCell.View>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<Button Text="Done" HorizontalOptions="CenterAndExpand"
CommandParameter="{Binding .}" Clicked="Button_Clicked"/>
</StackLayout>
I am getting following output.
Control with purple background is my Entry. Text is not displayed correctly. Any help will be appreciated. Thanks in advance.
I have already posted question in Xamarin Forums here.
<Grid Padding="5,0" RowSpacing="1" ColumnSpacing="1">
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="auto" />
</Grid.ColumnDefinitions>
<Label Text="Apple" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Margin="2" VerticalTextAlignment="Center" BackgroundColor="Green" />
<Switch Grid.Row="0" Grid.Column="2" VerticalOptions="Center" HorizontalOptions="Center" BackgroundColor="Brown" />
<Entry Text="CountStr" Grid.Row="0" Grid.Column="3" IsEnabled="false" HorizontalOptions="Center" FontSize="Small" BackgroundColor="Purple"/>
</Grid>
Note: I sub'd in a Switch vs. your 3rd-party Checkbox
use StackLayout like this
<StackLayout Padding="5,0" Orientation="Horizontal">
<Label Text="{Binding Title}" WidthRequest="120" Margin="2" BackgroundColor="Green"/>
<common:CheckBox HeightRequest="20" WidthRequest="20" Checked="{Binding isChecked, Mode=TwoWay}" CheckedImage="checkbox_checked" UnCheckedImage="checkbox_unchecked" CommandParameter="{Binding .}" BackgroundColor="Brown"/>
<Entry WidthRequest="120" IsEnabled="False" Text="CountStr" FontSize="Small" VerticalOptions="End" BackgroundColor="Purple" />
</StackLayout>
you can change the Size using the WidthRequest property and HorizontalOption="FillAndExpand"
My XAML looks like this:
<StackLayout Orientation="Vertical" HorizontalOptions="Center">
<controls:BindablePicker HorizontalOptions="Center" />
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<ListView Grid.Row="0" Grid.Column="1" HorizontalOptions="Center" SeparatorVisibility="None">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<ViewCell.View>
<Grid BackgroundColor="Aqua">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<controls:BindablePicker Title="Length" Grid.Row="0" Grid.Column="0" BackgroundColor="White" />
<controls:BindablePicker Title="Units" Grid.Row="0" Grid.Column="1" BackgroundColor="White" />
</Grid>
</ViewCell.View>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
</StackLayout>
Here's what I'm getting: Attempt
This is pretty much what I want, except I want the content centered within the aqua area so everything is centered horizontally. I don't mind if the left cell is right justified and the right cell is left justified.
Note that I'm wanting to add other content beneath this, like labels and other grids, all centered on the page.
Any help would be greatly appreciated. Thanks.
First of all I do not think that you need a row definition in your inner grid since you have only one row.
Secondly for performance sake,do not user "Auto" , just remove the width property from the column definitions.
By doing this both columns will have the same width... I hope ;)
I think if you made your list view like below then it would fix it, but also try it without HorizontalOptions for the controls.
<ListView Grid.Row="0" Grid.Column="1" HorizontalOptions="Center" SeparatorVisibility="None">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<ViewCell.View>
<Grid BackgroundColor="Aqua">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<controls:BindablePicker Title="Length" Grid.Column="0" BackgroundColor="White" HorizontalOptions = "End" />
<controls:BindablePicker Title="Units" Grid.Column="1" BackgroundColor="White" HorizontalOptions = "Start" />
</Grid>
</ViewCell.View>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Hint: The next release of Xamarin.Forms, which is in the alpha channel now, contains a bindable picker so you do not have to user a 3rd party now.
