    text
    copied!<p>I want to use MVVM in my WPF application. I currently have a Model and a view which has DataGrid and some other controls. I created a ViewModel based on my model and don't know if I did it correctly. The view is just a simple dialog box. I want to fill the DataGrid view.</p> <p>How can I tell the DataGrid to bind with the ViewModel?</p> <p><strong>I would like to bind properties(inside viewmodel like ID and Date) to the datagrid</strong>.</p> <p><strong>SO like if there is two objects inside the list I would like to see two rows in datagrid with the specific ID's and Date's.</strong></p> <p>Im setting the datacontext inside the class instead xaml.</p> <p>Here is the code so far:</p> <pre class="lang-cs prettyprint-override"><code>public class ViewModel : INotifyPropertyChanged { private string _id; private DateTime _date; private ObservableCollection&lt;Object&gt; _list; public string Id { get { return _id; } set { _id = value; PropertChanged("Id"); } } public DateTime Date { get { return _date; } set { _date = value; PropertChanged("Date"); } } public ObservableCollection&lt;Object&gt; list { get { return _list; } set { _list = value; PropertChanged("list"); } } public LicenseViewModel() { list = GetList(); } public event PropertyChangedEventHandler PropertyChanged; public void PropertChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } } </code></pre> <p>And the XAML:</p> <pre><code>&lt;Window x:Class="Import" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" mc:Ignorable="d" ResizeMode="CanResizeWithGrip" x:Name="ImportLicense" d:DesignHeight="493" d:DesignWidth="559" Title="Import Licenses" SizeToContent="WidthAndHeight"&gt; &lt;Grid Width="538"&gt; &lt;DataGrid x:Name="Imported" VerticalAlignment="Top" AutoGenerateColumns="False" CanUserResizeColumns="True"&gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Header="Entitlement ID" Binding="{Binding Path=ID}"/&gt; &lt;DataGridTextColumn Header="Date Sold" Binding="{Binding Path=Date}"/&gt; &lt;/DataGrid.Columns&gt; &lt;/DataGrid&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre>
