Currently, the calculation of the actual ScaleFactor is based only on Worksheet`s UsedCellRange.

The content of the merged cells is measured and affects the CenterHorizontally behavior. Only the first cell from the merged range should have content. This is the default behavior in MS excel when cells are merged as well.

Implement text orientation for cell content import/export from/to XLSX format

NullReferenceException when the FindOptions does not contain start cell

Workaround:

Set StatCell like this:

FindOptions options = new FindOptions()
{
    FindWhat = "Record",
    MatchEntireCellContents = true,
    StartCell = new WorksheetCellIndex(workbook.Worksheets[0], new CellIndex(0,0))

};

The calculation takes into account the height of the cell instead of the height of the row. 

ArgumentOutOfRangeException is thrown when a document containing Image which size is not set and cannot be obtained is exported to PDF 

When inserting row or column before cell containing reference to another worksheet the reference should not be translated.

If the lookup_value parameter and lookup_vector parameters refer cells containing text values, the function returns a Not available error ("#N/A").

Currently, this could be achieved by exporting the document to PDF and then by using RadPdfViewer's WPF control ThumbnailFactory class. Sample code may be seen at this forum post: http://www.telerik.com/forums/pdf-thumbnail-returns-transparent-images#jO33X-E8Cki_qLh_KsToWg Help article: WPF PdfViewer - Exporting Fixed Page to Image - Telerik UI for WPF

Add an option to save or load a custom created DocumentTheme.

Currently, this could be achieved this way:

Setting SetIsBold method to true on a CellSelection, resets the font size of those cells to 11 points.
See the generated file of the attached program.
Cells C1:F1 have font size 11 instead of expected 9.

 

PS: Is it really necessary to have a support plan to report bugs?

The colors of the charts are determined by the theme in the default scenario. However, customers can apply any color to the series and the legend respectively. In such cases, RadSpreadProcessing doesn't import the custom colors and uses the ones defined by the theme.

The columns of the sheet are split when exporting to PDF.

Wrong measured column width when exporting to PDF after binaries version 2019.2.624.

One should be able to set the axis titles in the code. The attached images show an example of the exported document opened in Excel. 

Add support for MID function. MID returns a specific number of characters from a text string, starting at the position you specify, based on the number of characters you specify.

MID(text, start_num, num_chars)

A list of the supported functions is available at http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/functions

This function can be implemented as a custom function. Check the following resources for more details on how to achieve that:

- http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/custom-functions
- https://github.com/telerik/xaml-sdk/tree/master/Spreadsheet/WPF/CustomFunctions

Add support for the Data Labels in the chart (see attached).

The exception is thrown when importing a document that contains a not supported BuiltInNumberFormat.

While importing the arguments of the data validation rule, the formula is treated as text and its separators are replaced with the list separator defined in the current culture. This leads to an invalid formula treated as a list of strings.
