Hey there,

I am having troubles rerendering/reloading/reimporting the fixed/preferred width of a table within the RichTextBox:

Here is how I insert my table:

var table = new Table

{

Borders = new TableBorders(new Border(1, Telerik.WinControls.RichTextBox.Model.BorderStyle.Single, Color.Black)),

LayoutMode = TableLayoutMode.Fixed,

PreferredWidth = new TableWidthUnit(200)

};

for (int i = 0; i < 2; i++)

{

var row = new TableRow();

for (int j = 0; j < 2; j++)

{

var cell = new TableCell

{

Background = Color.White,

Padding = new Padding(3)

};

var paragraph = new Paragraph();

var span = new Span { Text = "c"+ i + j };

paragraph.Inlines.Add(span);

cell.Blocks.Add(paragraph);

row.Cells.Add(cell);

}

table.Rows.Add(row);

}

this

.richTextBox.InsertTable(table);

This works fine. The RichTextBox control inserts the table with the preferred width. The HTML code it creates after exporting is:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>Untitled</title>

<style type="text/css"

>  .p_384D933F { margin: 0px 0px 0px 0px;text-align: left;text-indent: 0pt;padding: 0px 0px 0px 0px; }   .s_6BF1D20F { font-family: 'Calibri';font-style: normal;font-size: 16px;color: #000000; }   .p_CC664AAA { margin: 0px 0px 12px 0px;text-align: left;text-indent: 0pt;padding: 0px 0px 0px 0px; }   .tbl_77AF2C2D { border-collapse: collapse;table-layout: fixed;width: 200px; }   .tc_C0034B80 { border-left: 1px solid #000000;border-top: 1px solid #000000;border-right: 1px solid #000000;border-bottom: 1px solid #000000;padding: 3px 3px 3px 3px;background-color: #FFFFFF;vertical-align: top; }   </

style>

</head>

<body>

<p class="p_384D933F"><span class="s_6BF1D20F"> </span></p>

<table class="tbl_77AF2C2D">

<tr>

<td class="tc_C0034B80" align="left" valign="top">

<p class="p_CC664AAA"><span class="s_6BF1D20F">c00</span></p>

</td>

<td class="tc_C0034B80" align="left" valign="top">

<p class="p_CC664AAA"><span class="s_6BF1D20F">c01</span></p>

</td>

</tr>

<tr>

<td class="tc_C0034B80" align="left" valign="top">

<p class="p_CC664AAA"><span class="s_6BF1D20F">c10</span></p>

</td>

<td class="tc_C0034B80" align="left" valign="top">

<p class="p_CC664AAA"><span class="s_6BF1D20F">c11</span></p>

</td>

</tr>

</table>

<p class="p_384D933F"><span class="s_6BF1D20F"> </span></p>

</body>

</html>

Rendering it in any browser also works fine. The table's width is still 200.

However, if I try to import that HTML into the RichTextBox control again:

IDocumentFormatProvider provider = new HtmlFormatProvider();

Byte[] convertedText = Encoding.ASCII.GetBytes(htmlStream);

RadDocument document = provider.Import(convertedText);

richTextBox.Document = document;

The RichTextBox control renders the table with auto-fit style, means the table's fixed width 200 renders incorrectly.

Am I doing anything wrong in the import call or is this a bug in the control?

Thanks,
Jean

Hello Jean,

I managed to reproduce the issue. It seems that PreferredWidth property is not imported/exported correctly. I logged the issue in our Public Issue Tracking System. Meanwhile, you need to use the following code snippet:

RadDocument document = provider.Import(fs);

richTextBox.Document = document;

foreach (Table t in richTextBox.Document.EnumerateChildrenOfType<Table>())

{

t.PreferredWidth = new TableWidthUnit(200);

}

richTextBox.DocumentView.UpdateEditorLayout();

I updated your Telerik points for the feedback.

All the best,
