How do I set the name of a Label in Xamarin Forms

xamarin forms label formattedtext
xamarin forms multiline label
xamarin forms label ellipsis
xamarin.forms label text binding
xamarin forms label number of lines
xamarin change label text on button click
xamarin label style
xaml label

I'm trying to add a name to a label so I can find it using the Content.FindByName<>() method

as far as I can tell the Xamarin.Forms.Label() class doesn't have a Name property

Here is my page class

public class HelloWordCodePage : ContentPage
{
    public Label HelloWorldLabel;

    public HelloWordCodePage()
    {
        HelloWorldLabel = new Label{Text = "Hello World", };
        ConstructView();
    }

    public void ConstructView()
    {
        Content = new StackLayout
        {
            Children =
            {
                HelloWorldLabel
            }
        };
    }
}

If you define your label in Xaml, you can use this syntex:

<Label x:Name="YourLableName" Text="A simple Label" />

And then access it in the code behind like this

YourLableName.Text = "bla bla"

However, if you don't use Xaml, and all your page definition is found in the code behind, you should keep a reference to that label in order to access it instead of finding it using Content.FindByName<>() as @Sten Petrov commented

Xamarin.Forms Label, None; Underline; Strikethrough. The following XAML example demonstrates setting the Label.TextDecorations property: XAML If you define your label in Xaml, you can use this syntex: <Label x:Name="YourLableName" Text="A simple Label" />. And then access it in the code behind like this. YourLableName.Text = "bla bla".

I believe the name is only meant to be used when creating the element in XAML. If you look at the inheritance you will find Element at the bottom and it implements INameScope explicitly. You cannot cast Label to INameScope as that is an internal interface:

namespace Xamarin.Forms
{
    internal interface INameScope
    {
        object FindByName(string name);

        void RegisterName(string name, object scopedElement);

        void UnregisterName(string name);
    }
}

Is It Possible To Give A Name Or Id To Element , Forms. Hey everyone. I want to name a picker, or give it a name. element within the xaml page and it will create a member with that name in the code behind file. foreach(Label someLabel in myLabelList) { if (someLabel. VS 2019 with all updates. I install Xamarin.Forms.Map using nuget. Using Xamarin Android to display a map with a pin point. Front end XAML is <ContentPage.Content>; &lt;maps:Map x:Name=&qu

The Name is assigned at the Render processing stage. There is no need to know the rendered name at this time as you are working on a cross-platform ContentPage.

There is a GUID, but like you say there is no ID. You wouldn't in my opinion ever want to get a platform-specific ID for the generated control at this high a level of page design. If you do then perhaps you need to create a platform-specific PageRenderer instead?

When you start to write CustomRenderers and create platform specific controls you can then assign IDs if you so wish any custom control platform specific implementations you want.

Remember on the current ContentPage - you have a class-scoped object reference already to your label named HelloWorldLabel, that you can use to change its appearance etc on the page when in execution.

How do I set the name of a Label in Xamarin Forms, I'm trying to add a name to a label so I can find it using the Content.FindByName<​>() method as far as I can tell the Xamarin.Forms.Label() class doesn't have a  Remarks. A Label is used to display single-line text elements as well as multi-line blocks of text. The following example, adapted from the default Xamarin.Forms solution, shows a basic use:

StyleId

Use the StyleId property to identify individual elements in your application for identification in ui testing and in theme engines.

Code-behind x:Name not linking properly · Issue #2574 · xamarin , Steps to Reproduce. Create a new blank Xamarin Forms project. Add 'x:Name="myTextLabel" ' to the default "Welcome to Xamarin.Forms" label, and 'x:Name="myContentPage" ' to the default ContentPage. Try and reference them in the code-behind. According to Github, FreshMvvm is a super light Mvvm Framework designed specifically for Xamarin.Forms. It's designed to be simple and flexible. It has many built-in features, for example automatic wiring up of Binding Context and PageModel to PageModel Navigation, just to name a few. I hope I do not need to mention about Xamarin.Forms J.

As IdoT says, if you define an object at runtime, you need to keep a reference to that in order to access it as it is not possible to assign a name. I use a dictionary like this:

Dictionary<Guid, String> ControlsDictionary = new Dictionary<Guid, string>(); 

Then when I create an object:

Button bt = new Button {Text="Yay!"};

        bt.Clicked += OnButtonClicked;
        StackLayout.Children.Add(bt);

        ControlsDictionary.Add(bt.Id, "myname");

In the Click event handler I can identify the sender "name":

async void OnButtonClicked(object sender, EventArgs args)
    {

        Button btn = (Button)sender;
        String NameofButton = ControlsDictionary[btn.Id];

    }

also you can obtain the Id from the "name":

Guid IdfromName = ControlsDictionary.First(x => x.Value == "myname").Key;

Xamarin.Forms: How to create a Labeled Switch as custom control , Xamarin.Forms has an control included which is called Switch. We want to extend this control by adding a title and a detail label to it and if you  you could always change your objects using code-behind. x:name generates a field and you can use it in code behind. but it's not a smart way of implementing . As I said it's highly recommended to use databinding insted. using a pattern like MVVM is a plus – esiprogrammer Jan 20 '17 at 12:13
