I'm trying to display a Lable.Text using a Binding with a string (Tables: ) followed by an Integer(TableCount).
I've tried using:
<Label x:Name="tableCountLable" Text="{Binding TableCount, StringFormat='Table Count: {0:N}'}"
VerticalOptions="Center"/>.
Also, I've tried:
<Label x:Name="tableCountLable">
<Label.Text DisplayMemberBinding="{Binding Path=TableCount, StringFormat=Tables: {0:N}}"
VerticalOptions="Center"/>
</Label>
In both cases, the preceding text (Tables: ) does not disply. Only the integer (TableCount) displays.
The integer cant be seen on the upper left of the button labeled "Tables"
I would appreciate someone pointing me to an answer.
Thanks in Advance
StringFormat docs
<Label Text="{Binding TableCount, StringFormat='Tables: {0}'}" />
I write a demo about it, Here is running GIF.
I used your StringFormat code like following format.
<Label Text="{Binding Count , StringFormat=' Table Count: {0:N}' } "
FontAttributes="Bold"
FontSize="Large"
HorizontalOptions="Center"
VerticalOptions="Center" />
My version of xamarin forms nuget package is 4.5.0.530 .
I update my demo to github, you can download it.

Good day fellow code ninjas!!!
Using a '< TabbedPage/ >' in Xamarin forms I can easily create a tab bar at the top of my page. I would however like to have two tab bars instead of one. For example, 3 tab buttons in the first tab bar row and another 3 in the second row and the user being able to navigate between all 6 pages.
Does anyone perhaps know if this is possible in Xamarin forms and/or if there is any documentation that might assist.
You could use the TabView from the Xamarin Community Toolkit in addition to your TabbedPage 😉. Here's how it works:
<Grid>
<xct:TabView>
<xct:TabViewItem>
<Grid>
<Label
HorizontalOptions="Center"
VerticalOptions="Center"
Text="TabContent1" />
</Grid>
</xct:TabViewItem>
<xct:TabViewItem>
<Grid>
<Label
HorizontalOptions="Center"
VerticalOptions="Center"
Text="TabContent2" />
</Grid>
</xct:TabViewItem>
</xct:TabView>
</Grid>
If you put a TabView in each of your TabBar contents you will be able to get the result you want.
In your case, it would be something like this:
<ContentPage Title="Tab 1">
<xct:TabView>
<xct:TabViewItem>
<Grid>
<Label
HorizontalOptions="Center"
VerticalOptions="Center"
Text="TabContent1" />
</Grid>
</xct:TabViewItem>
<xct:TabViewItem>
<Grid>
<Label
HorizontalOptions="Center"
VerticalOptions="Center"
Text="TabContent2" />
</Grid>
</xct:TabViewItem>
</xct:TabView>
</ContentPage>
<ContentPage Title="Tab 2">
<xct:TabView>
<xct:TabViewItem>
<Grid>
<Label
HorizontalOptions="Center"
VerticalOptions="Center"
Text="TabContent1" />
</Grid>
</xct:TabViewItem>
<xct:TabViewItem>
<Grid>
<Label
HorizontalOptions="Center"
VerticalOptions="Center"
Text="TabContent2" />
</Grid>
</xct:TabViewItem>
</xct:TabView>
</ContentPage>
If you want to see more about TabViews, there is a great article posted by Gerald Versluis, that explains it perfectly: https://devblogs.microsoft.com/xamarin/xamarin-community-toolkit-tabview/
Give it a try with James Montemagno youtube channel
EDIT
here is the official github link for the library used by that video

Any idea how to create this. I am using ProgressRingBar but it has some limitations. I want to show progress in percentage also inside the ring. Which is not possible with this
Any other way to achieve this for both Android and iOS platforms
Got this working:
<control:ProgressRing Margin = "165,0,-20,40" Grid.Row="0" Grid.Column="1" HeightRequest= "40" RingProgressColor="#ebf5e4" RingBaseColor="LightGray" RingThickness="25" AnimatedProgress="{Binding Progress}" AnimationEasing="2" />
<Label x:Name="LabelProgress" Margin = "200,0,-20,40" Grid.Row="0" Grid.Column="1" FontSize="Micro" Text="{Binding ProgressPercentage}" WidthRequest="50" HeightRequest="20" VerticalOptions="Center" HorizontalOptions="Center" />
I use a label with a ProgressRing to show the percentage of progress. This works for me.
I'm styling in Xamarin Forms. I have problem with align Vertical 2 label other size:
This is my XAML code:
<StackLayout HorizontalOptions="EndAndExpand" Grid.Row="0" Grid.Column="1">
<StackLayout Orientation="Horizontal" HorizontalOptions="FillAndExpand">
<Label Text="03" FontSize="42" FontAttributes="Bold" Style="{StaticResource LabelNormal}" HorizontalTextAlignment="End" VerticalTextAlignment="End" />
<Label Text="\20" Style="{StaticResource LabelNormal}" HorizontalTextAlignment="End" VerticalTextAlignment="End" />
</StackLayout>
<Label Text="Chưa xỠlý" Style="{StaticResource LabelNormal}" HorizontalTextAlignment="End" />
</StackLayout>
I want "30" and "/20" are straight on bottom. How I can do it?
Resovled
This is my simple solution. I added Margin-bottom is "-7" and it worked.
<Label Text="03" FontSize="42" FontAttributes="Bold" Style="{StaticResource LabelNormal}" HorizontalTextAlignment="End" VerticalTextAlignment="End" Margin="0,0,0,-7" />
While your solution is working it might be not the best, please consider the next topics:
Negative values in padding can introduce inconsistent side effects on different screens and platforms. It should be considered as a very dirty hack and should be avoided.
Performance. It seems that you overused StackLayout. Try Grid, it will reduce the amount of UI elements to render and will increase the loading time.
Good luck!
I have a listview in which I have displayed all the employee name, address, and phone number.Now my task is to click on the label of the phone to make a phone call in xamarin forms.
Please help me to get the value of the binding label into the backend of the code.
<Label FontSize="14" x:Name="BtnCall" TextColor="Black" Text="{Binding Phone}" HorizontalOptions="StartAndExpand" VerticalOptions="Center" >
<Label.GestureRecognizers>
<TapGestureRecognizer
Tapped="OnPhoneTapped">
</TapGestureRecognizer>
</Label.GestureRecognizers>
</Label>
I will really appreciate your help.
I don't how to center the icon inside the button and get it above the text, I didn't find information also about it, I'm asked to do a kind of "tabb" option menu, but below the screen, and I found that it was kind of "hard" because of the "design implications"etc, so I decided that with buttons would be easier, but the problem now is how to center the image and get the text right, If some one could help me, that would be great. This is my code so far:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
BackgroundColor="Silver"
x:Class="XamForm.View.MainPage">
<Label Text="{Binding MainText}" VerticalOptions="Center" HorizontalOptions="Center" />
<StackLayout Padding="30">
<Label x:Name="lblCuantos" Text="No #" TextColor="Gray" FontSize="20"/>
<Label x:Name="lblNombre" Text="" FontSize="20"/>
<Button x:Name="btn1" Text="Oprimir" Clicked="Accion"/>
<Button x:Name="btn2" BackgroundColor="White" Image="iconRes.png" HorizontalOptions="CenterAndExpand" Text="Gridd" TextColor="Gray" Clicked="Accion2"/>
<Button x:Name="btn3" BackgroundColor="White" Image="iconRes.png" HorizontalOptions="CenterAndExpand" TextColor="Gray" Clicked="Accion2"/>
</StackLayout>
</ContentPage>
This is the actual result of the button itself:

This is what the final result of the menu should look like kind off

Thank you!
You can use ContentLayout="Top,0" in button. For Example in your case use below code
<Button x:Name="btn2" ContentLayout="Top,0" BackgroundColor="White" Image="iconRes.png" HorizontalOptions="CenterAndExpand" Text="Gridd" TextColor="Gray" Clicked="Accion2" />
<Button x:Name="btn3" ContentLayout="Top,0" BackgroundColor="White" Image="iconRes.png" HorizontalOptions="CenterAndExpand" TextColor="Gray" Clicked="Accion2"/>
You could use a StackLayout with Orientation set to Vertical, and in it add Button and Label.
The Button.Image property is of type FileImageSource so any image that is 'local' can be used in a button. This means the following code will work:
someButton.Image = "imageName.png";
or you can write
someButton.Image = ImageSource.FromFile("imageName.png");
if imageName.png is located in each of the application projects (Resources folder in iOS, Resources/Drawable folder in Android, and application root in WinPhone; each with the appropriate build action set).
The Xaml equivalent is:
<Button Text="Has Image" Image="someImage.png" />
See the Working with Images doc for full details of what the build action should be for each platform.
