set autogeneratecolumns to true and just set data1 as itemssource

xaml

 <DataGrid x:Name="dataGrid1" AutoGenerateColumns="True" />

EDIT: to get the power of WPF look into DataBinding/MVVM

XAML is like this:

<DataGrid ItemsSource="{Binding}" />

code behind is this:

public MainWindow()
{
    InitializeComponent();
    DataContext = data1;
}

and remove this line:

dataGrid1.ItemsSource = data1.ToArray();

 data1.Add(new gm { no = 2, name = "vipul" }); // Remore ellipsis around gm.

In XAML just check the following that

You have DataSource of your datagrid to {Binding Path="data1"}
DataColumn of no have binding to {Binding Path="no"}
DataColumn of name have binding path to {Binding Path="name"}
