System.ArgumentException: 'An item with the same key has already been added. Key: Telerik.Windows.Documents.Fixed.Model.InteractiveForms.RadioButtonField'

It is reproducible when you have at least 2 pages with RadioButtonFields. The import operation goes smoothly. However, merging or removing a page after import leads to the described error.

Error message: 

Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.MarkedContents.StructAttributeObject'.

InvalidCastException is thrown when importing a document with a structure element with an indirect reference to an integer value.

InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.MarkedContents.StructElementObject'.'

When you register a font in an ASP.Core project and in a static constructor, the generated PDF document will have this font only the first time you load the web page. Refreshing the page will generate the PDF document but the fonts will be lost.

Note: This worked in the previous version  2025.2.701.

Exported text content:

The current implementation of IDisposable implements a simple Dispose method which releases the inner stream resource. However, if the PdfStreamWriter instance is not disposed explicitly by calling Dispose() or by surrounding it in "using" clause, then the inner Stream resource is not Disposed as well. The same applies for PdfFileSource class.

We should implement the IDisposable pattern in a way that the GC disposes the inner stream if needed when collecting the PdfStreamWriter/PdfFileSource class instances.

 Tables should ignore fixed proffered width with the value of 0, this is the default behavior in Word as well.

Workaround (when converting Flow to PDF documents): 

foreach (var item in tables)
{
    if (item.PreferredWidth.Type == Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnitType.Fixed && 
        item.PreferredWidth.Value == 0)
    {
        item.PreferredWidth = new Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnit(Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnitType.Percent, 100);
    } 
  
    
}

When creating a data bar conditional formatting with middle axis, a plain data bar with left axis is created instead. Using the following code:

var dataBarValueContext = new DataBarValueContext
{
    MaximumValue = new NumericValue(1),
    MinimumValue = new NumericValue(-1)
};
// Create the rule and set the desired formatting
var rule = new DataBarRule(dataBarValueContext)
{
    UseGradientFill = false,
    Direction = DataBarDirection.Context,
    FillColor = ThemableColor.FromColor(Colors.Green),
    NegativeFillColor = ThemableColor.FromColor(Colors.Red),
    ShowBarsOnly = true,
    AxisPosition = DataBarAxisPosition.Automatic
};

var conditionalFormat = new ConditionalFormatting(rule);

worksheet.Cells[0, 0, 1, 0].AddConditionalFormatting(conditionalFormat);
worksheet.Cells[0, 0].SetValue(0.5);
worksheet.Cells[1, 0].SetValue(-0.5);

The expected value is this:

The result value is instead:
