Binding Data to Data Grid in WPF

In this post we are going to learn how to bind data to DataGrid in WPF(Windows Presentation Foundation)  
Create new project named as DataGridSample 
  



To show a basic data grid, just drop a DataGrid control to your view and bind the ItemsSource to a data table
The DataGrid provides a feature called AutoGenerateColumns that automatically generates column according to the columns of your data datatable. It generates the following types of columns:
  • TextBox columns for string values
  • CheckBox columns for boolean values
  • ComboBox columns for enumerable values
  • Hyperlink columns for Uri values
MainWindow.xaml
<Grid>
      <DataGrid AutoGenerateColumns="True" Height="225" HorizontalAlignment="Left"Margin="28,21,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="408" />
</Grid>
MainWindow.xaml.cs
        SqlConnection cn = new SqlConnection("Data     Source=.;database=Practice;trusted_connection=true");
        public MainWindow()
        {
            InitializeComponent();
        }
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            cn.Open();
            SqlDataAdapter da = new SqlDataAdapter("Select * from Employee", cn);
            DataSet ds = new DataSet();
            da.Fill(ds, "Employee");
            dataGrid1.ItemsSource = ds.Tables["Employee"].DefaultView;
        }

Alternatively you can define your columns manually by setting the AutoGenerateColumnsproperty to False. 
Here we can add following type of columns 
DataGridCheckBoxColumn
DataGridComboBoxColumn
DataGridHyperlinkColumn               
DataGridTemplateColumn
DataGridTextColumn
MainWindow.xaml
<DataGrid AutoGenerateColumns="False" Height="173" HorizontalAlignment="Left"Margin="12,12,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="292" ItemsSource="{Binding}">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding EmpId}" Header="Id" />
<DataGridTextColumn Binding="{Binding EmpName}" Header="Name" />
<DataGridTextColumn Binding="{Binding Designation}"    Header="Designation" />
<DataGridTextColumn Binding="{Binding Location}" Header="Location" />
<DataGridCheckBoxColumn Binding="{Binding IsActive}" Header="IsActive" />
 </DataGrid.Columns>
 </DataGrid>
