Question

I have a button that when clicked will run a stored procedure on a SQL Server and display the resulting data in a grid within the same window.

In windows forms world, I’d create a datatable, use a dataadapter to fill it and then assign the datatable to the DataSource propert of my DataGridView and poof… there’s my data.

I’m tried something similar in WPF using a ListView with a Gridview and i cant seem to make it work. I have the following in my XAML:

<ListView Grid.Row="1" Name="Preview" ItemsSource="{Binding Path=Report}">
  <GridView>
    <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=FormalName}" />
  </GridView>
</ListView>

And in my C# code

private void CreateReport(object sender, RoutedEventArgs e) 
{
  DataTable dt = new DataTable("Report");
  SqlConnection cn = new SqlConnection("Data Source=DailyTimesheets;
             Initial Catalog=DailyTimesheets;Integrated Security=SSPI");

  SqlCommand cm = new SqlCommand("Reports.PayrollHoursInterface", cn);
  cm.Parameters.AddWithValue("@PayBatchID", 722);
  cm.CommandType = CommandType.StoredProcedure;

  SqlDataAdapter da = new SqlDataAdapter(cm);
  da.Fill(dt);

  Preview.DataContext=dt;
}

When I clicka the button (that fires the CreateReport Method), my datatable gets filled and assigned to the Datacontext, but nothing displays.

I made a sample app and discovered you need to surround your GridView with ListView.View and set your ItemsSource to {Binding} just like the following:

<ListView Name="Preview" ItemsSource="{Binding}">
<ListView.View>
  <GridView>
    <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=FormalName}" />
  </GridView>
 </ListView.View>
</ListView>
