XAML для грида выглядит тривиально:
1: <Window x:Class="StoreHouse.MainWindow"
2: xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3: xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4: Title="Тест Грида" Height="350" Width="525">
5: <Grid>
6: <DataGrid Name="gridProducts" AutoGenerateColumns="True">
7: </DataGrid>
8: </Grid>
9: </Window>
