Currently, if there is an unsupported feature in the imported document it is stripped and not preserved in the document model (the Workbook). When exporting the Workbook the resulting document contains only the supported features.

Wrongly exported image size when the size of the image is different than the original image size in .NET Standard.

According to the Open XML documentation, the possible max value for this attribute is an unsignedInt or 4294967295.

Microsoft Excel supports 2 types of date. Date is the number of days starting from 1/1/1900 or 1/1/1904. The first one is the default the second one has been added cause Macintosh supports it. The Microsoft library supports both of them and you can choose programmatically which one you prefer (https://docs.microsoft.com/en-us/dotnet/api/microsoft.office.interop.excel._workbook.date1904?view=excel-pia). Expose such an option in SpreadProcessing as well.

To reproduce: 

- Add the following formula to a cell: "=A1=FALSE"

Actual: the result is always false

Expected: the result should be true when the cell is empty

 

Workaround: Use the ISBLANK function.

The chart axes are not correctly imported when there are floating and sheet charts

The Office Open XML model doesn't support the transparency of the colors inside a document. Even if an alpha channel is used for the colors, this should not be respected by SpreadProcessing and the colors should be without any opacity.

When importing a spreadsheet document whose cells use a style that is not defined in the document stylesheet, a KeyNotFoundException is thrown. The style can be just skipped so that the document can be imported without errors.

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.

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

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))

};

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

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

Text is cut off when exporting to pdf with a specific font.

Hi Telerik,

 

I would like to request 1 feature to be added in Current RADGRID control which is to exporting grid data to into Excel 2016 version.

We need this feature because one of our supporting application will work only with  Excel 2016 version, where as the current RADGRID conversion only able to export to EXCEL 2007 (excel 12) format.

 

Thank you.

 

 

When a row or column is inserted in a worksheet that has cells referred from another worksheet, the formula should be updated so it refers to the same values as before the insertion or removal of cells.

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

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

Currently, this could be achieved by exporting the document to PDF and then by using RadPdfViewer's WPF control ThumbnailFactory class.
