[Hakki]

Hello,

I get the following error when trying to export to PDF:

Here is my code:

var saveDialog = new SaveFileDialog
               {
                   DefaultExt = "*.pdf",
                   Filter = "Adobe PDF Document (*.pdf)|*.pdf"
               };

           if (saveDialog.ShowDialog() != true) return;

           var table = new Table(1, CheckGrid1.Columns.Count);

           var document = new RadDocument();
           document.Sections.Add(new Section());
           document.Sections.First.Blocks.Add(table);

           TableCell headerCell = table.Rows.First.Cells.First;
           AddCellDataSpan(headerCell, "ID", Colors.DarkGray, Colors.White, RadTextAlignment.Center);
           headerCell = (TableCell) headerCell.NextSibling;
           AddCellDataSpan(headerCell, "Check Date", Colors.DarkGray, Colors.White, RadTextAlignment.Center);
           headerCell = (TableCell) headerCell.NextSibling;
           AddCellDataSpan(headerCell, "Check Description", Colors.DarkGray, Colors.White, RadTextAlignment.Center);

           var everyTwo = 0;
           var doubleChecker = 1;

           foreach (var item in CheckGrid1.Items.OfType<GridBinding>())
           {
               var row = table.AddRow();

               var index = 0;
               foreach (var cell in row.Cells)
               {
                   switch (index)
                   {
                       case 0:
                           AddCellDataSpan(cell, item.CheckIDColumn.ToString(CultureInfo.InvariantCulture),
                                           everyTwo == doubleChecker ? Colors.LightGray : Colors.White, Colors.Black,
                                           RadTextAlignment.Center);
                           break;
                       case 1:
                           AddCellDataSpan(cell, item.checkDateColumn,
                                           everyTwo == doubleChecker ? Colors.LightGray : Colors.White, Colors.Black,
                                           RadTextAlignment.Center);
                           break;
                       case 2:
                           AddCellDataSpan(cell, item.CheckDescColumn,
                                           everyTwo == doubleChecker ? Colors.LightGray : Colors.White, Colors.Black,
                                           RadTextAlignment.Center);
                           break;
                   }

                   index++;
               }

               if (everyTwo == doubleChecker)
                   doubleChecker += 2;

               everyTwo++;
           }

           document.LayoutMode = DocumentLayoutMode.Paged;
           document.Measure(RadDocument.MAX_DOCUMENT_SIZE);
           document.Arrange(new RectangleF(PointF.Empty, document.DesiredSize));

           var extension = Path.GetExtension(saveDialog.SafeFileName);

           var provider = DocumentFormatProvidersManager.GetProviderByExtension(extension);

           if (provider == null)
           {
               MessageBox.Show("Unsupported file format.");
               return;
           }

           try
           {
               using (var output = saveDialog.OpenFile())
               {
                   provider.Export(document, output);
               }

               MessageBox.Show("File '" + provider.Name + "' has been saved.", "PDF Success", MessageBoxButton.OK);
           }
           catch (Exception ex)
           {
               MessageBox.Show("Unable to save the file: " + ex);
           }

I have referenced all FormatProviders and document and documentFixed. Is it a case of missing reference or is something else going on?

Hello,

Would you please Clean and Rebuild your solution and try again? You should also check if all the references are with the same versions.

All the best,

Ah, yes....a couple of references were outdated. A simple run of Upgrade Wizard from the Telerik toolbar solved the problem.

Thanks.

However I am curious as I thought it picked up outdated references when launching the project and prompted you to update?

Hi,

Thank you for the update. Sometimes the Visual Studio seems to run the older code and that is why Cleaning the project help. 

Kind regards,
