    Hi guys,

    The app im working on freezes when I print a gridview that has a datapager on it.The problem comes in when setting the pagesize to 0 
    and then when resetting the pagesize back to its the original size once the export has completed [BeginExport + Exported in code]. And Inbetween this I have the CreateDocument. I am using a radDocument. Everything is fine when exporting to pdf but printing large amounts of data doesnt work. I see someone had a similar problem and it was never resolved.

    Thanks.

    protected override void ExportButtonClicked(object sender, RoutedEventArgs routedEventArgs)
            {
                var document = new RadDocument();
     
                Dispatcher.BeginInvoke(() =>
                {
                    if (BeginExport != null)
                        BeginExport();
     
                    if (ControlWithGridView != null)
                        document = CreateDocument(ControlWithGridView.GridView);
                    else if (GridView != null)
                        document = CreateDocument(GridView);
     
                    RadRichTextBox.Document = document;
                     
                    if (Exported != null)
                        Exported();
                });
     
     
                RadRichTextBox.Print("Prof1t", PrintMode.Native);
                 
                RadRichTextBox.Document.History.Clear();
     
                 
            }

    Hello Tyrone,

    I am trying to reproduce your setup here but I am missing the part with the DataPager. Can you please either paste me some more code so I can see the whole context or even better  - a small runnable projectthat demonstrates the issue  over which I can try add some workarounds and send the modified version back to you.
