Exception when the sheet name contains a single letter 

The filter icon is shown in merged cells after import export

Currently, the text orientation for cell content is not exported when exporting to PDF format.

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

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.

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.

 

 

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.

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.

When a formula contains new lines, it is parsed incorrectly as follows:

- When it is shared formula it breaks the imported expression and replaces it with #NAME? error.
- In normal case it simply preserves the formula string converting it to StringExpression.

Workaround: Remove the new lines in the formulas.

Have in mind that this code will fix the issue only for the second scenario, when the formula is not shared.

CellRange usedCellRange = workbook.ActiveWorksheet.UsedCellRange;

for (int row = usedCellRange.FromIndex.RowIndex; row < usedCellRange.ToIndex.RowIndex; row++)
{
    for (int column = usedCellRange.FromIndex.ColumnIndex; column < usedCellRange.ToIndex.ColumnIndex; column++)
    {
        CellSelection cell = workbook.ActiveWorksheet.Cells[row, column];
        ICellValue value = cell.GetValue().Value;

        if (value.RawValue.Contains("\n"))
        {
            cell.SetValue(value.RawValue.Replace('\n', ' '));
        }
    }
}

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

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").
