Can I programmatically add a row to a WPF datagrid?

I just want to add a new row, I have my datasource in objects in which I need to do some processing. i need something like below for wpf datagrid...

DataRow row = dataTable.N开发者_JAVA百科ewRow();
foreach (NavItem item in record.Items)
{
    row[item.FieldNo.ToString()] = item.RecordValue;
}
dataTable.Rows.Add(row);

You should be using an ObservableCollection<NavItem> as the datagrid source. Then simply adding a new element to your collection will add it to the datagrid.

See this MSDN article.

I do not know if it is the right solution, but I came up to something like this, in desperation:

foreach (NavField field in this.Fields)
 {
      DataGridTextColumn column = new DataGridTextColumn();
      column.Header = field.FieldNo.ToString();

      //Some other logic
      // Hide non active and hidden fields
      if (!field.Active || !field.Show)
           column.Visibility = System.Windows.Visibility.Collapsed;

       grid.Columns.Add(column);
  }

Then I add the datatable as itemssource:

  this.dataGridLines.ItemsSource = dataTable.DefaultView;

If I set the datatable directly, it does not care about the columns from the datatable and autogenerate its own columns, don't know why..
