Border Created with RadFlowDocumentEditor not displayed in RadRichTextBox

[Michael]

Borders I am creating with RadFlowDocumentEditor are not displayed in Radrichtextbox, to demonstrate here is my test code, I am using Telerik UI for WPF R2 2019.

Attached is the file, also how it is displayed in Word and the how it is displayed in the RadRichTextBox inside my application.

 

using System.Windows;
using System.Windows.Controls;
using Telerik.Windows.Controls;
using Telerik.Windows.Documents.FormatProviders.Html;
using System.Linq;
using System;
using System.IO;
using Telerik.Windows.Documents.Flow.Model;
using Telerik.Windows.Documents.Flow.Model.Editing;
using Telerik.Windows.Documents.Flow.Model.Styles;
using Telerik.Windows.Documents.Spreadsheet.Model;

 public void CreateCell(RadFlowDocumentEditor documentEditor, Table table, int row, int column, string text, FontWeight fw, float Width, Alignment alignment, double fs = 0)
        {
            while (table.Rows[row].Cells.Count < (column + 1))
            {
                table.Rows[row].Cells.AddTableCell();
            }
            Paragraph newPara = table.Rows[row].Cells[column].Blocks.AddParagraph();
            table.Rows[row].Cells[column].PreferredWidth = new TableWidthUnit(Width);
            table.Rows[row].Cells[column].Padding = new Telerik.Windows.Documents.Primitives.Padding(2);
            newPara.TextAlignment = alignment;
            documentEditor.MoveToParagraphStart(newPara);
            var line = documentEditor.InsertText(text);
            line.FontWeight = fw;
            if (fs > 0) line.FontSize = fs;
        }

Hi Michael,

Thank you for sharing the sample code with us.

After taking a look, I noticed that the border thickness of the Table and the TableCell borders are not specified. When the border thickness is not specified, the border is exported with a default value of zero. However, by specification, the default value of the exported borders thickness should be two, which causes the issues you are currently encountering. We have logged this in our feedback portal: Table and TableCell borders width is exported with default value of zero when not specified, where you can subscribe to be notified for any status updates. As a possible workaround, you may specify the border thickness when the border instance is created. For example:

table.Borders = new TableBorders(new Border(thickness, BorderStyle.Single, new ThemableColor(Colors.Black)));

In appreciation for pointing out this to our attention, I have increased your Telerik points.

Regards,
Georgi
