Add support for "Invert if negative" property of chart data series fill.
In Excel this can be achieved by right click on the axis, then from the context menu select "Format Axis". Go to the "Text Options" tab and "Text Box" group and then in the "Custom angle" field insert the desired value.
Optimize font fallback mechanism.
Currently, in NET Standard, if no fonts are provided on PDF export, while resolving the fonts the application falls back to different fonts multiple times for each cell which causes a decrease in performance.
It would be beneficial for the clients if every cell has this "cached value" even if the formula can't be evaluated for some reason with the SpreadProcessing - no need for recalculation, just reading the value. It should read the last values while the document was being saved at the originator.
Getting a method like "GetCachedValueString ..." , ideal with the same formatting used for the cell and localization, would be helpful.
Currently, these are the supported image formats:
If we try to import an Excel document containing an image with another format, the following error occurs:
System.Collections.Generic.KeyNotFoundException: 'The given key was not present in the dictionary.'
string fileName = "file.xlsm";
Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsm.XlsmFormatProvider();
using (Stream input = new FileStream(fileName, FileMode.Open))
{
workbook = formatProvider.Import(input);
}
Add support for images embedded in cells.
Similar to clicking "Place in Cell' in MS Excel which embeds the floating image into the cell:
Alternative: Floating Images
I am using .net 7. I originally hit it with Telerik.UI.for.Wpf.70.Xaml.2023.3.1114. I updated to Telerik.UI.for.Wpf.70.Xaml.2024.1.423 to see if it was fixed but it still appears to happen.
I have attached a sample program which shows the behavior. Original.xlsm was created in Excel and has an image embedded in cell A1. Call ImportWorkbook with the path to the original file. Then export that workbook (unchanged) to the destination file.
Workbook workbook = ImportWorkbook( originalFileName ); ExportWorkbook( workbook, destinationFileName );
private Workbook ImportWorkbook( string fileName )
{
Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsm.XlsmFormatProvider();
using( Stream input = new FileStream( fileName, FileMode.Open ) )
{
workbook = formatProvider.Import( input );
}
return workbook;
}
private void ExportWorkbook( Workbook workbook, string fileName )
{
Telerik.Windows.Documents.Spreadsheet.FormatProviders.IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsm.XlsmFormatProvider();
using( Stream output = new FileStream( fileName, FileMode.Create ) )
{
formatProvider.Export( workbook, output );
}
}
Incorrectly resolved fill between local formatting and cell style.
A fill (fillId) of a cell style (cellStyleXfs) is respected instead of the fill (fillId) of the local formatting (cellXfs).
