Data Binding

[hadi1370]

سلام
داخل آموزشی که آقای وحید نصیری برای data binding گذاشتن مشکل داشتم.
داخل این برنامه دو تا پوشه داریم یکی به اسم Model و یکی دیگه به اسم ViewModel. داخل Model یه کلاس دارم به اسم MyCustomer :

 
using System;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Ink;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;



namespace DataBinding.Model

{

    public class MyCustomer

    {

        public string FirstName { get; set; }

        public string LastName { get; set; }

        public int Age { get; set; }

        public string Country { get; set; }

    }

}

و کلاس CustomerViewModel رو در داخل پوشه ی ViewModel دارم:

using System;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Ink;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using DataBinding.Model;



namespace DataBinding.ViewModel

{

    public class CustomerViewModel

    {

        public MyCustomer Customer { get; set; }



        public CustomerViewModel()

        {

            this.Customer = new MyCustomer

            {

                FirstName = "Hadi",

                LastName = "Sinaee",

                Age = 21,

                Country = "Iran"

            };            

        }

    }

}

حالا داخل MainPage.xaml کد های زیر رو دارم( چند تا label و چند تا textBox دارم ):

<UserControl x:Class="DataBinding.MainPage"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"             

    mc:Ignorable="d"  Loaded="UserControl_Loaded"  

    xmlns:src="clr-namespace:DataBinding.Model"

    d:DesignHeight="300" d:DesignWidth="400" xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk">    

    <Grid x:Name="LayoutRoot" Background="White">        

        <sdk:Label Height="22" HorizontalAlignment="Left" Margin="12,26,0,0" Name="label1" VerticalAlignment="Top" Width="71" Content="First Name"/>

        <sdk:Label Height="22" HorizontalAlignment="Left" Margin="12,58,0,0" Name="label2" VerticalAlignment="Top" Width="71" Content="Last Name"/>

        <sdk:Label Height="22" HorizontalAlignment="Left" Margin="12,94,0,0" Name="label3" VerticalAlignment="Top" Width="71" Content="Age"/>

        <sdk:Label Height="22" HorizontalAlignment="Left" Margin="12,131,0,0" Name="label4" VerticalAlignment="Top" Width="71" Content="Country"/>        

        <TextBox Height="23" HorizontalAlignment="Left" Margin="107,22,0,0" Name="textBox1" VerticalAlignment="Top" Width="120"  Text="{Binding MyCustomer.FirstName}"/>        

        <TextBox Name="textBox2" Margin="108,54,173,222" HorizontalAlignment="Center" VerticalAlignment="Center" Width="119" />

        <TextBox Height="23" HorizontalAlignment="Left" Margin="107,90,0,0" Name="textBox3" VerticalAlignment="Top" Width="120" />

        <TextBox Height="23" HorizontalAlignment="Left" Margin="107,127,0,0" Name="textBox4" VerticalAlignment="Top" Width="120" />

        

    </Grid>

</UserControl>

داخل MainPage.xaml.cs هم دارم:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using DataBinding.ViewModel;

namespace DataBinding

{

    public partial class MainPage : UserControl

    {

        public MainPage()

        {

            InitializeComponent();

            

            this.DataContext = new CustomerViewModel();

        }      

    }

}
