At this point the PdfFormatProvider does not support floating images and these elements are skipped when exporting to PDF.

The feature is trivial for floating images with "Behind Text"/"In Front of Text" settings, but otherwise floating images are affecting the text layout in complex ways.

Implement support for content controls (a.k.a. Structured document tags), which will allow inserting editing controls in the document:

- Rich Text
- Plain Text
- Check Box
- Combo Box
- Drop-down list
- Date picker

Do not confuse this feature with form fields support (see https://feedback.telerik.com/Project/184/Feedback/Details/219850 ).

The API should allow you to perform a text-based search and return the parent element(s) of the result(s) or directly the found element(s).

This feature includes: table of figure, table of tables etc.

TOC field contains PageRef fields inside it. To update it, we will need pagination (layout) support and PageRef fields implementation. Also TOC update can be influenced by TC fields presence in the document.

Implement export to PDF.

Implement nested mail merge and master-detail scenario.

The attached sample project below demonstrates a possible workaround for PAGE and NUMPAGES fields when exporting to PDF. The demo shows how to generate document from scratch containing PAGE and NUMPAGES fields and export it to PDF.

Add support for shapes, and especially for shapes with textual content. 
In OOXML, shapes are represented by the wps:wsp element, and shapes with textual content by <wps:txbx>, <w:txbxContent>.
Such shape can be added to a Word document using the Insert -> Text -> Text Box -> Draw Text Box, or through a shape's context menu -> Add Text.

Do not confuse these shapes with Text/Rich Text content controls (see https://feedback.telerik.com/Project/184/Feedback/Details/190057 )

If a worksheet spans more than one page, you can print row and column headings or labels (also called print titles) on every page to ensure that the data is properly labeled.

They are exported with the /EmbeddedFiles switch. This would allow adding external files to the PDF document.

Implement repeating header row for tables when exporting with PdfFormatProvider.

A similar functionality can be achieved using the editing API of RadPdfProcessing. There is attached a project showing a sample implementation. More details are available in the forum post at http://www.telerik.com/forums/repeat-table-heading-after-page-break#kH616fyAKUiDl6WAknUILg

Support conversion of XPS documents to PDF using RadPdfProcessing.

Enable the customers to work with .doc files.

These file formats are very similar to DOCX, and can be easily imported with loss of some information (e.g. macros).

This API should provide a method for removing all fields and widgets in the document and draw the default widget appearance in place of the removed widgets.

WORKAROUND: Sample implementation for flattening form fields may be seen in the FlattenFormFields method from the attached demo project.

For example when some PDF file has uncompressed contents we may import it and apply better compression to the stream objects. 

Add support for conditional formatting of cells - allow applying of rules used during visualization of cells to automatically apply formatting depending on their values.

Introduce an option to replace a Run text with line breaks and/or new lines or with other document elements such as Table, Image, Paragraph and etc. 

The following code snippet shows how a Run can be replaced with another inline element:

RadFlowDocument document = new RadFlowDocument();
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
 
editor.InsertText("text");
editor.InsertText("REMOVE");
editor.InsertText("text");
 
foreach (Run run in document.EnumerateChildrenOfType<Run>().ToList())
{
    if (run.Text == "REMOVE")
    {
        Paragraph paragraph = run.Paragraph;
        int childIndex = paragraph.Inlines.IndexOf(run);
 
        ImageInline image = new ImageInline(document);
        using (Stream stream = File.OpenRead("example_image.png"))
        {
            image.Image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(stream, "png");
        }
 
        paragraph.Inlines.Insert(childIndex, image);
        paragraph.Inlines.Remove(run);
    }
}

Provide ability for working with comments in a spreadsheet document.

Add support for documents containing RTL (right-to-left) text.
