Add support for pivot tables.
trying to open the attached workbook with this code:
Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
using (Stream input = File.OpenRead("sample.xlsx"))
{
var provider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();
// The import method enables you to also pass a byte[] with the XLSX document data
workbook = provider.Import(input, TimeSpan.FromSeconds(30));
}
I get an unhandled exception:
An unhandled exception of type 'System.ArgumentNullException' occurred in Telerik.Documents.Spreadsheet.dll
Value cannot be null.
Any idea what's going on?
Thank you for your time,
Phil
As Ghiath reported in the forum thread, I am seeing this same error.
I am using RadFixedDocument and am generating a PdfFormatProvider. As Ghiath mentioned it will work fine (weeks, months) and then it seems the the font file is locked and it cannot export.
System.IO.IOException: I/O error when opening file 'C:\WINDOWS\FONTS\MSYH.TTC'.

It will throw the exception on the line where it is doing the export. The document is typically a multi-page document with images, etc. As I mentioned it might work fine for weeks and then once it fails the only solution is to recycle the web service.
Use the following code to create the document:
Workbook workbook = new Workbook();
Worksheet graphWorksheet = workbook.Worksheets.Add();
FloatingChartShape chartShape = new FloatingChartShape(graphWorksheet,
new CellIndex(0, 0),
new CellRange(0, 0, 0, 0), ChartType.Column)
{
Width = 500,
Height = 500,
};
graphWorksheet.Charts.Add(chartShape);
DocumentChart chart = new DocumentChart();
BarSeriesGroup barSeriesGroup = new BarSeriesGroup();
barSeriesGroup.BarDirection = BarDirection.Column;
StringChartData barCategoryData = new StringChartData(new List<string>() { "1.1", "1.2", "1.3", "1.4", "2.1", "3.1", "4.1", "4.2", "4.3" });
IEnumerable<double> percentEvidentList = new List<double>() { Math.Round((double)0.9914 * 100, 4) , Math.Round((double)0.7719 * 100, 4), Math.Round((double)1 * 100, 4) };
NumericChartData barValues = new NumericChartData(percentEvidentList);
BarSeries series = new BarSeries();
series.Categories = barCategoryData;
series.Values = barValues;
ThemableColor themableColor = ThemableColor.FromArgb(255, 125, 0, 125);
series.Fill = new SolidFill(themableColor);
series.Title = new TextTitle("FY 20");
barSeriesGroup.Series.Add(series);
chart.SeriesGroups.Add(barSeriesGroup);
ValueAxis valueAxis = new ValueAxis();
valueAxis.Min = 0;
valueAxis.Max = 100;
valueAxis.NumberFormat = "0%";
CategoryAxis categoryAxis = new CategoryAxis();
chart.PrimaryAxes = new AxisGroup(categoryAxis, valueAxis);
chart.Legend = new Legend();
chart.Legend.Position = LegendPosition.Left;
chartShape.Chart = chart;
valueAxis.NumberFormat = "0%";
string outputFilePath = "SampleFile.xlsx";
File.Delete(outputFilePath);
IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();
using (Stream output = new FileStream(outputFilePath, FileMode.Create))
{
formatProvider.Export(workbook, output, TimeSpan.FromSeconds(10));
}
Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
The value of the TextBoxField is not visible until the field is clicked.
Workaround: Force content update:
foreach (var widget in textBoxField.Widgets)
{
widget.RecalculateContent();
}If the update still doesn't fix the issue, change the font prior to setting the value of the field:
foreach (var widget in textBoxField.Widgets)
{
widget.TextProperties.Font = FontsRepository.Helvetica;
}RESOLVED: The issue is dismissed. The actual reason for the results is that FontsProvider implementation is missing. For accurately displaying the text the fonts used in the document need to be resolved correctly.
Getting an exception message when trying to view a document as a PDF using the PdfFormatProvider which started happening only after upgrading Telerik to the latest version, 7.1.0 in Telerik UI for Blazor.
Exception Message:
width should be greater or equal than 0. (Parameter 'width')

RadPdfProcessing currently supports interactive forms whose data is defined directly in the document. To preserve them when importing and exporting documents, add support for import-export interactive forms based on the Adobe XML Forms Architecture (XFA).
From PDF 2.0 the XFA forms are depreciated.
Implement repeating header row for tables when exporting with PdfFormatProvider. A similar functionality can be achieved using the editing API of RadPdfProcessing. There is attached a project showing a sample implementation. More details are available in the forum post at http://www.telerik.com/forums/repeat-table-heading-after-page-break#kH616fyAKUiDl6WAknUILg
