Hello!

I have a problem with RichTextBox. I need to create RadDocument for RichText in code. It contains tables. If I add InlineUIContainers to table cells, RichText doesn't behave properly after scrolling - it moves table cells content to random places in Document.

Where is my mistake?

public void createRadDocument()

{

var BaseRadDocument = new RadDocument();

BaseRadDocument.LayoutMode = DocumentLayoutMode.Flow;

BaseRadDocument.ParagraphDefaultSpacingAfter = 0;

BaseRadDocument.PageViewMargin = new SizeF(0, 0);

BaseRadDocument.SectionDefaultPageMargin = new Padding(0);

Section section = new Section();

CreateSection(0, section);

BaseRadDocument.Sections.Add(section);

rich.Document = BaseRadDocument;

}

public void CreateSection(int level, Section section)

{

for (int i = 0; i < 15; i++)

{

createDocElementsForNewItem(i, section);

}

private void createDocElementsForNewItem(int level, Section section)

{

int indent = 20 * level;

var cell_11 = new TableCell();

cell_11.PreferredWidth = new TableWidthUnit(80 + indent);

var cell_12 = new TableCell();

Paragraph paragraph_113 = new Paragraph();

Size firstSize = new Size(100, 20);

TextBlock start = new TextBlock();

start.Text = String.Format("start|{0}", level);

start.Tag = String.Format("start|{0}", level);

InlineUIContainer containerFirst = new InlineUIContainer(start, firstSize);

paragraph_113.Inlines.Add(containerFirst);

Paragraph paragraph_111 = new Paragraph();

paragraph_111.LeftIndent = indent;

paragraph_111.SpacingAfter = 0;

paragraph_111.SpacingBefore = 0;

paragraph_111.TextAlignment = RadTextAlignment.Right;

Span date = new Span(String.Format("{0} ", DateTime.UtcNow.ToShortDateString()));

date.FontSize = 12;

date.ForeColor = new Color() { A = 0xff, B = 0x68, G = 0x68, R = 0x68 };

date.FontFamily = new FontFamily("Calibri");

paragraph_111.Inlines.Add(date);

Paragraph paragraph_112 = new Paragraph();

paragraph_112.LeftIndent = indent;

paragraph_112.SpacingAfter = 0;

paragraph_112.SpacingBefore = 0;

paragraph_112.TextAlignment = RadTextAlignment.Right;

Span time = new Span(String.Format("{0} ", DateTime.UtcNow.ToLongTimeString()));

time.FontSize = 12;

time.ForeColor = new Color() { A = 0xff, B = 0x68, G = 0x68, R = 0x68 };

time.FontFamily = new FontFamily("Calibri");

paragraph_112.Inlines.Add(time);

paragraph_112.LeftIndent = indent;

for (int j = 0; j < 5; j++)

{

var span = new Span(String.Format("Текст {0}", j));

var par = new Paragraph();

par.Inlines.Add(span);

cell_12.Blocks.Add(par);

}

Paragraph paragraph_12n = new Paragraph();

Size lastSize = new Size(100, 20);

TextBlock finish = new TextBlock();

finish.Text = String.Format("end|{0}|{1}", level, indent);

finish.Tag = String.Format("end|{0}|{1}", level, indent);

InlineUIContainer containerLast = new InlineUIContainer(finish, lastSize);

paragraph_12n.Inlines.Add(containerLast);

cell_11.Blocks.Add(paragraph_113);

cell_11.Blocks.AddAfter(paragraph_113, paragraph_111);

cell_11.Blocks.AddAfter(paragraph_111, paragraph_112);

cell_12.Blocks.Add(paragraph_12n);

var row_1 = new TableRow();

row_1.Cells.Add(cell_11);

row_1.Cells.AddAfter(cell_11, cell_12);

Table table = new Table();

table.Rows.Add(row_1);

section.Blocks.Add(table);

section.Blocks.Add(new Paragraph());

}

private void UserControl_Loaded(object sender, RoutedEventArgs e)

{

createRadDocument();

}
