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);
}
}

Read the documentation for CancelationTokenSource.CancelAfter:
this method will throw an ArgumentOutOfRangeException when: delay.TotalMilliseconds is less than -1 or greater than Int32.MaxValue (or UInt32.MaxValue - 1 on some versions of .NET). Note that this upper bound is more restrictive than TimeSpan.MaxValue.
----------------------------------------------------
your code in CancelationTokenSourceFactory.CreateTokenSource does this check:
if (timeSpan.HasValue && timeSpan.Value != TimeSpan.MaxValue)this check for TimeSpan.MaxValue seems totally pointless here, if timeSpan is anything between ~2147483647 and 922337203685476 milliseconds long this will still just throw a ArgumentOutOfRangeException.
I suspect that this check was intended as a way to prevent creating a cancellation timer that never triggers in the CancellationTokenSource, which should look like this:
if (timeSpan.HasValue && timeSpan != Timeout.InfiniteTimeSpan) //Timeout.InfiniteTimeSpan is -1 milliseconds
InvalidCastException is thrown when importing a document with a structure element with an indirect reference to an integer value.

PDF content:
Exported text content:
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.

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:
