Binding Control to Control in Xamarin Forms

Databinding is a mechanism in Xamarin Forms Application. Binding is common context, is the process of mapping a property on a Page, to a property in a view or ViewModel. In this Article I will show how bind Control property to Control property binding in xamarin Forms.

Create New Xamarin. Forms Application:

Let's start with creating a new Xamarin Forms Project in Visual Studio.

Open Run - Type Devenev.Exe and enter - New Project (Ctrl+Shift+N) - select Blank Xaml App (Xamarin.Forms Portable) template.

You can refer my previous article for create new xamarin forms application from here -

Binding Control to Control using xaml :

Data bindings can be defined to link properties of two Controls on the same page. In this case, you set the BindingContext of the target object using the x: Reference markup extension.

In the following sample added one Entry control and Label control for print text

<Entry x:Name ="txtname"></Entry>
<Label Text="Welcome Mr.." VerticalOptions="Center" HorizontalOptions="Center" />
<Label BindingContext="{x:Reference Name=txtname}" Text="{Binding Path=Text}"
VerticalOptions="Center" HorizontalOptions="Center" />
Entry Control Name : txtname

Label control adding Binding Context and Binding the value.

While assign binding Context, we can use following two way

BindingContext="{x:Reference Name=txtname} OR BindingContext="{x:Reference txtname} // Name attribute is not required

Same like while assign value to property, we can use following two way

Text="{Binding Path=Text}" OR Text="{Binding Text}" // Path attribute is not required

Binding Control with String Builder:

All the database data or other srorage data is not formatted data so you Can bind Property with string or any type like below

<Label BindingContext="{x:Reference Name=txtname}" Text="{Binding Path=Text, StringFormat='Welcome Mr {0}'}"/>
<Entry x:Name ="txtname"></Entry>
<Label BindingContext="{x:Reference Name=txtname}" Text="{Binding Path=Text, StringFormat='Welcome Mr {0}'}"
HorizontalOptions="Center" />

Binding Control in C#:

You can do it effectively the same way as the XAML example simply by setting your view's BindingContext or Source to the other view.

label.SetBinding(Label.TextProperty, new Binding("<Property Name>", stringFormat: "Welcome Mr {0}", source: <BindingContext Control name>));


var label = new Label{ BindingContext = <Control Name> };
label.SetBinding(Label.TextProperty, new Binding("<Property Name>", stringFormat: "Welcome Mr {0}"));
StackLayout layout = new StackLayout();
var editor = new Editor();
var label = new Label();
label.SetBinding(Label.TextProperty, new Binding("Text", stringFormat: "Welcome Mr {0}", source: editor));
this.Content = layout;

Binding User Control:

Xamarin Forms doesn’t have a control called a User Control. However, we can make any VisualElement, or combination of Visual Element’s into a reusable control, to use on different pages, just like a User Control.

Create User Control:

Right Click PCL project > Select” Forms XAML View” and click on Add

In xaml and C# file, change content View to any layout control like Grid, Stack layout

In Xaml Page:

<?xml version="1.0" encoding="UTF-8"?>
<Grid xmlns="" xmlns:x="" x:Class="MVVMXamarin.MyControl">
<Label Text="{Binding Text, Source={x:Reference this}}" />

In Code behind file, you might want to make your control, have a bindable property to pass data through to it, on each page it is used. First, create a Bindable Property in your UserControl. It doesn’t have to be bindable if you just want to pass a static value through, however if you want to bind to it, you must make it bindable.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Xamarin.Forms;
namespace MVVMXamarin
public partial class MyControl : Grid
public MyControl()

public static readonly BindableProperty TextProperty = BindableProperty.Create(nameof(Text), typeof(string), typeof(MyControl));
public string Text
return (string)GetValue(TextProperty);
SetValue(TextProperty, value);

Going to your MainPage, you can now assign a value to the Text property. You can also use {Binding PropertyName} if you want, as this is a bindable property.

<Entry x:Name ="txtname"></Entry>
<local:MyControl BindingContext="{x:Reference Name=txtname}" Text="{Binding Path=Text, StringFormat='Welcome Mr {0}'}">
