Print / print preview error message: Eval failed.

[Edward]

At first it can print fine.  But after several attempts (didn't count but at least 10) it will begin to throw an error message "Eval failed" when calling the editor.Print line.  Once it starts to fail the app cannot print anymore and has to restart IE.

   at System.Windows.Browser.HtmlWindow.Eval(String code)
   at Telerik.Windows.Documents.UI.HtmlPrinter.Print(RadDocument document, PrintSettings settings, Boolean preview)
   at Telerik.Windows.Controls.RadRichTextBox.Print(PrintSettings printSettings)
   at Telerik.Windows.Controls.RadRichTextBox.Print(String documentName, PrintMode mode)
   at Kinark.KIDS4.SL.DocEditor.rtbEditor_CommandExecuting(Object sender, CommandExecutingEventArgs e)
   at Telerik.Windows.Controls.RadRichTextBox.OnCommandExecuting(CommandExecutingEventArgs e)
   at Telerik.Windows.Documents.RichTextBoxCommands.RichTextBoxCommandBase.Execute(Object parameter, Boolean focusCaret)

private void rtbEditor_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
{
    if (e.Command is PrintCommand)
    {
        if (e.CommandParameter != null && e.CommandParameter.ToString() == "Html")
        {
            rtbEditor.Print(Title, Telerik.Windows.Documents.UI.PrintMode.Html);
            e.Cancel = true;
        }

        if (e.CommandParameter != null && e.CommandParameter.ToString() == "HtmlPreview")
        {
            rtbEditor.Print(Title, Telerik.Windows.Documents.UI.PrintMode.HtmlPreview);
            e.Cancel = true;
        }
    }
}

Hi Edward,

Unfortunately, we were not able to reproduce this failure. Could you elaborate more about which version of RadControls for Silverlight you are using in your project? In case the problem is browser or OS specific, please include the exact version of the browser and operation system.

Looking forward to your reply.

All the best,
Vasil
