if you're using different form/window. In your save button, all you have to do is to save your data.

private void SaveButton_Click(object sender, RoutedEventArgs e)//Save Button
{


    this.db.Datastore("UPDATE [databasename].[dbo].[Machinedup] SET [Name] = '" + textBox1.Text   + "',[Type] = '" + comboBox1.SelectedItem + "',[AETitle] = '" + this.textBox2.Text + "',[IPAddress] = '" + textBox3.Text + "',[Port]='" + textBox4.Text + "' WHERE [ID] = '" + (string)(object)this.ID + "'");
else
    this.db.Datastore("INSERT INTO [databasename].[dbo].[Machinedup] ([Name],[Type],[AETitle],[IPAddress],[Port]) VALUES('" + textBox1.Text + "','" + comboBox1.SelectedIndex.ToString() + "','" + textBox2.Text + "','" + textBox3.Text + "','" + textBox4.Text + "')");
this.Close();

}

in the form where your datagrid is located, create a method that will refresh your datagrid

 public void refreshgrid()
{


 cmd = new SqlCommand("SELECT [Name],[Type] AS Type,[AETitle] AS AET,    [IPAddress] AS IP,[Port] AS PO FROM [databasename].[dbo].[Machinedup] WHERE ID ='" + (object)this.ID + "'",conn); 
        da = new SqlDataAdapter(cmd);

        dt = new DataTable("Machineup");
        da.Fill(dt);
        dataGrid1.ItemsSource = dt.DefaultView;

}

and in the window_loaded call the method.

  private void Window_Loaded(object sender, RoutedEventArgs e)
 {
   refreshgrid();
 }
