Provide a simple method to detect that a password for a ZIP file is not valid.

The current implemention usually throws an exception (which does not definitively identify the password as wrong), but not always. Sometimes it just returns corrupt data.

It would be nice to  either have a typed exception consistently thrown, or a method to specifically check for an invalid password.

Thanks. 

I was working on some acroforms and wherever I needed a space I kept on getting a different letter (Ê). On debugging the problem seems to be in the TryGetCharCode function of OpenTypeFontSource

Version: 2019.3.917

Below is copy of function

public override bool TryGetCharCode(int unicode, out int charCode)
        {
            bool result = false;
            ushort glyphId;
            charCode = CMap.MISSING_GLYPH_ID;
            if (this.TryGetGlyphId(unicode, out glyphId))
            {
                ushort uCharCode = CMap.MISSING_GLYPH_ID;
                CMapTable table = this.CMap.GetCMapTable(3, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                table = this.CMap.GetCMapTable(1, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                charCode = uCharCode;

                return result;
            }

            return false;
        }

The font used has 2 cmap tables: one with platformid of 3 and encodingid of 1, the other with platformid 1 and encodingid 0. According to https://docs.microsoft.com/en-us/typography/opentype/spec/cmap platform id 3 and encoding 1 is correct for windows so not sure why the first call to getcmaptable looks for encodingid 0.

Second of all even if I change it to the following

CMapTable table = this.CMap.GetCMapTable(3, 1);

if there is a second cmap with platformid of 1 whatever the result of the call with regards to platformid 3, the result will be overridden

I can say that if I add some checks so that if the first call succeeds it doesn't attempt the 2nd I do get the expected behaviour in the pdf and get spaces

As a note the FontFamily property of the OpenTypeFontSource is "Arial"

I would like to request an example of the RadPdfProcessing library utilizing a Line Chart similar to how the Bar Chart is drawn in this example. 

Additionally, it would be great if there was an example with multiple charts on one page.

Thank you!

This request is to ask that the development team review the code inside the Documents for refactoring to see if certain things can be reduced (like Generics).

When using the Telerik UI for Xamarin and referencing the UI.for.Xamarin NuGet package, the assembly reference for the Telerik.Documents.Fixed.dll is added to the project. This increases the amount of code that is compiled when the Linker is only set to SDK only, thus breaking AOT compilation with LLVM enabled.

A few addition insights:

- When the project cannot set the Linker to SDK and User Assemblies

- When individually referencing DLLs for only what the project uses is an insufficient solution

- When installing sub-packages like Telerik.UI.for.Xamarin.DataGrid is an insufficient solution.

Thank you.

ArgumentException with clarification similar to "'\u001f', hexadecimal value 0x1F, is an invalid character." is thrown when trying to export document containing characters which are not supported in XML document - such as some control characters like 0x00, 0x1F, 0x1B, etc.

Such characters are described in the XML specification here: https://www.w3.org/TR/xml/#charsets.

using (var stream = File.OpenWrite("sample.xlsx"))
using (var workbook = SpreadExporter.CreateWorkbookExporter(SpreadDocumentFormat.Xlsx, stream))
using (var worksheet = workbook.CreateWorksheetExporter("My sheet"))
using (var row = worksheet.CreateRowExporter())
using (var cell = row.CreateCellExporter())
{
      cell.SetValue(string.Format("Error Value: {0} ", Encoding.ASCII.GetString(new byte[] { 8 })));
}

Closed as duplicate. Please, follow the item at https://feedback.telerik.com/Project/184/Feedback/Details/190249 .

The format string for dates should be in lowercase so they can work as expected. Ensure this in the internal logic.

When iterating through the rows and cells of an imported Worksheet in at least one of the rows GetValue().Value.ResultValueType for a number cell is set to GetValue().Value.ResultValueType.Text and the value to "error" or "string".

For us this happens in a worksheet with 200 rows max. and columns formated as date, time, time followed by some text and number columns.
In our Tests with different excel files it allways happened once (between line 11 and 16) and only for the first two columns.

Exporting the worksheet back into a new excel file will show all rows and columns types and values OK.

In business or enterprises there is more and more demand for PDF/A-3.

In Germany it is Zugferd for hybrid invoices, in Brazil Nota Fiscal Eletronica 2.0, in France FACTUR-X.

Also for longterm preservation it is import to support PDF/A-3.

If I would be the PM of this library this would be my number one priority!

This property will control whether a table row may start on one page and end on the next page.

Declined: Duplicate with https://feedback.telerik.com/Project/184/Feedback/Details/190081-wordsprocessing-respect-tablerow-cansplit-property-when-exporting-to-pdf.

This would allow to disallow some rows from splitting.

Introduce support for cell reference ranges which refer to whole columns. For example "=Sheet1$A:$A" refers to the whole column A.

When defaultThemeVersion is missing from the file, some styles are not shown when the document is opened in MS Excel.

When I need to populate a cell that I find using a DefinedName  I should parse RefersTo to get Worksheet name. But DefinedName class contains Scope property which has  CurrentWorksheet and Workbook properties (internal). It would be very useful if these properties could be public.
