I'm able to export data to an .xlsx file.  That file is exported to E:/SaoApps/Sims/wwwroot/exports and the user has full control over that folder.  The file successfully is created at that location.  But the file doesn't open or offer download to the user and the error message is:

In the attached code snippet, the passed exportsFolder = "E:/SaoApps/Sims/wwwroot/exports/" and passed lanId = "DSS"

"An error occurred trying to start process 'E:/SaoApps/Sims/wwwroot/exports/ContactsSearchResults_DSS.xlsx' with working directory 'E:\\Workspace\\Intranet\\Sims\\Sims'. The process cannot access the file because it is being used by another process."

Hello

I'm trying to create an Excel xlsx spreadsheet from data in a data table. I'm having trouble setting / defining cell borders. I would like to define a bottom black thin border for a range of cells.

I'm using this as a reference https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/working-with-cells/get-set-clear-properties#borders-property

I've started with this...

Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets.Add();

ThemableColor black = new ThemableColor(Color.FromArgb(0, 0, 0, 0));
CellBorders blackBorders = new CellBorders(new CellBorder(CellBorderStyle.Thin, black));
worksheet.Cells[4, 0, 4, 9].SetBorders(blackBorders);

In Visual Studio, ThemableColor and Color are underlined in red. When I mouse over it says 'The name 'Color' does not exist in the current context'.

Am I missing a reference or using statement to be able to use ThemableColor?

Hello,

I am trying to upload the stream object received from the 'ToXlsxStream' method of Telerik SpreadSheet processing library to Azure blob container. Unfortunately, it is saving as a blank excel file. I have data in the List object which is getting converted to xlsx stream. Not sure why the excel file is blank. Tried to save the stream to my local file explorer as well. Still, the issue persists. 

Below is the code:

  try
   {
Stream exportStream = exportFormat == SpreadDocumentFormat.Xlsx ? workOrderList.ToXlsxStream(columnsData, (string)options.title.ToString(), cellStyleAction: cellStyle) : workOrderList.ToCsvStream(columnsData);

Task.Factory.StartNew(() => AzureHelper.UploadReportOnCloud(exportStream,fileName, ConfigurationManager.AppSettings[Constant.REPORTATTACHMENTCONTAINER]));

}

            catch(Exception ex)
            {

            }

Please help me to resolve this issue.  

I need to open a spreadsheet from a template in my project.  I'm referencing this article: https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/working-with-workbooks/create-open-and-save-workbooks#open-a-workbook

The immediate issue I have is I don't think I have the right libraries.  I'm starting just trying to open the file.  I get an namespace error.

public async Task PopulateReport()
{
    string filePath = "~/misc/report_template.xlsx";

    Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
    // the XLSX format provider is used for demo purposes and can be replaced with any format provider implementing the IWorkbookFormatProvider interface
            IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();

    using (Stream input = new FileStream(filePath, FileMode.Open))
    {
        workbook = formatProvider.Import(input);
    }
}

I have the Telerik.UI.for.Blazor package installed.  My understanding was that document processing was included.  What am I missing?  I guess its worth mentioning I don't have a login to Telerik Nuget.  I think it has to do with my company's licensing, I downloaded the package from an internal website.

I have data like this in CLOB field in the database. When a user downloads the data, it's converted to an Excel file using OpenXML.

Customer name¤Active¤customer id¤agreement name¤agreement id¤fund isin¤fund id¤rate active¤agreement active¤agreement vp key type¤agreement vp number¤rate type¤rate commision

I am converting the site so it can run in Kubernetes using the Blazor UI components. Today it's an old MVC site.

So how can I convert all the lines of code to an Excel sheet without using too much memory?

Each CLOB is around 32mb.

Hello,

It's not an issue with codepage or separator !

It's a projet DotNet Core 6 with last version 2023.2.713.20 of API

Do you have encountered this error already ?

Best regards

I do notice that the AutoFitHeight works fine when I'm dealing with only a single row without any merged cells.

I have a situation where I have a merged cell which is the combination of cells from the same row (i.e. B2-B5).  When trying to use AutoFitHeight, there is no change to the row height.

Is there anything I could do? 

I'm creating a spreadsheet Workbook, then exporting it to PDF. Each cell I write has a custom style where the FontSize is being set to 9 (and I'm also setting up fills and font effects, like bold).

When I get through writing the data to the Worksheet(s) in the Workbook, I then call AutoFitWidth on the Columns that have data.

Finally, I use the PdfFormatProvider to write the entire Workbook to a PDF file.

My problem is that text items in the cells are being clipped, even when there is room to fit them after calling AutoFitWidth.

For example:

It seems to be worse on strings with all caps. Sometimes it's just half a letter, other times it's multiple letters (the ATMOSPHERICCORR is supposed to be ATMOSPHERICCORROSION).

Here's another export in a different format:

As you can see, there's two problems based on calculating the required width. First is that AutoFitWidth is not giving enough space (mostly in the second example), but as you can see in the first example, even when there is enough horizontal space, it's still clipping off the text area within the cell.

Is the estimation assuming no caps, or is the font size/font family throwing it off (9pt)? Or am I missing something where I can force it to make more space?

Dear sir

When using Korean fonts, the text length is cut off. (Style problem)

There is no problem when using other products.

Is there a solution?
