Stretching columns to fill all available space of DataGrid

Question

Is it possible to stretch columns or the last column to fill all the available space of the data grid?

<DataGrid Grid.Row="0" AutoGenerateColumns="True" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Name="dataGrid1"   ItemsSource="{Binding Customers}" />

My columns are Auto generated.

Yes, I think you are looking for the AutoSizeMode property.

int n = grid.Columns.Count;
grid.Columns[n].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

Edit: Try setting the width to "*" as seen below. You'll have to do this in the code if your columns are auto-generated.

<DataGrid>
  <DataGrid.Columns>
    <DataGridTextColumn Width="Auto" />
    <DataGridTextColumn Width="*" />
  </DataGrid.Columns>
</DataGrid>
