Question

Trying to implement a simple print in SL4. I have a DataGrid that I would like to print out, but thus far whatever I try to print out comes out as a blank page in the printer. It also seems to take about 30-60 seconds to actually print out (but that could be an unrelated issue).

My code is fairly straightforward:

private void MenuPrint_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            PrintDocument document = new PrintDocument();
            document.PrintPage += (s, args) =>
                {
                    args.PageVisual = this.MainDataGrid;
                    // args.PageVisual = this.LayoutRoot;
                };

            // Print
            document.Print("Test Print Job");
        }

I’ve even wondered if it is because the items are too large?

The XAML for the MainDataGrid control is fairly straight-forward as well:

<sdk:DataGrid Grid.Row="3" AutoGenerateColumns="True" Name="MainDataGrid" FontSize="10" Visibility="Visible" />

Turns out this was PC-related and not a code issue after all. For whatever reason, the same code started working today (after a machine reboot).

The one thing that is still a problem is that the Silverlight interface does seem to hang for about 30-60 seconds while the printing is happening, but it eventually does release and print./
