Run's default constructor creates it with Text = null. When document with such run is exported to PDF, NullReferenceException is thrown.

Workaround: Create the Run and immediately set its Text property to string.Emtpy.

Although this is not a valid postscript scenario we should not throw exceptions and we should instead skip the invalid dictionary end characters.

The issue is observed with tables that have a specific width (in inches or percents) but whose columns do not have width specified. MS Word renders such tables expanded to their full width. For tables with 100% width, they have to expand to the entire width of the page. The same behavior is expected in the PDF export.

As a common side effect, when specific text alignment (e.g. center or right) is applied to a paragraph within a table cell, and the table is with specified width, but the column is auto-sized (without set width), then the text alignment seems as not respected. Actually the problem is that the column table is shrunk to the text width.

Workaround: this may be used before exporting the RadFlowDocument instance to PDF:

foreach (Table table in document.EnumerateChildrenOfType<Table>())
{
    table.LayoutType = TableLayoutType.FixedWidth;
}


Workaround 2:

Set specific width to the auto-sized columns (to any of the cells in the columns):

cell.PreferredWidth = new Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnit(500);

According to PDF specification, the resources used for the dynamic appearance of fields are defined globally in AcroForm "DR" PDF property. However, there are some invalid documents which define these resources locally in the field node which causes exception in PdfProcessing implementation. As there are several such documents we may consider handling such scenario instead of throwing the exception.

The MATCH function searches for a specified item in a range of cells and returns the relative position of the item found in this range.

A list of the supported functions is available at http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/functions

This function can be implemented as a custom function. Check the following resources for more details on how to achieve that:

The current implementation expects the widths to be integer values and InvalidCastException is thrown when a real number is parsed.

Workaround: If the scenario allows, the PdfStreamWriter may be used instead of PdfFormatProvider. More information may be found in the following documentation article:
