When <div> elements contain non-inline HTML elements, they and their styles are removed on import.
Input:
<div style="margin-left: 200px;">
<ol>
<li>Item 1</li>
<li>Item 2</li>
</ol>
</div>Output:
<ol style="list-style-type: decimal;">
<li value="1"><span>Item 1</span></li>
<li value="2"><span>Item 2</span></li>
</ol>
Workaround: Set the style properties to the inner elements. They will not disappear.
Workaround:
string html = File.ReadAllText("Source.html");
string newHtml = html.Replace("<br>", "[br]");
File.WriteAllText("NewSource.html", newHtml);using (Stream stream = File.OpenRead("NewSource.html"))
{
HtmlFormatProvider htmlFormatProvider = new HtmlFormatProvider();
flowDocument = htmlFormatProvider.Import(stream);
TxtFormatProvider txtFormatProvider = new TxtFormatProvider();
string text = txtFormatProvider.Export(flowDocument);
string newText = text.Replace("[br]", "\r\n");
}
I have created a very simple template (see attached file), import it, add my contents and later try to do a MailMerge.
However, the call to this function fails with the following exception:System.ArgumentException
HResult=0x80070057
Message=The document element is already associated with a parent.
Parametername: item

<ul>
<li>
<div>Text</div>
</li>
</ul>Workaround: Using other Html elements (e.g. <p> or <span>) instead of <div>
The empty lines are not converted properly from RTF to HTML
Workaround:
private static void FixEmptyParagraphs(RadFlowDocument document){
var paragraphs = document.EnumerateChildrenOfType<Paragraph>();
foreach (var paragraph in paragraphs)
{
if (paragraph.Inlines.Count < 1)
{
char nbsp = (char)160;
paragraph.Inlines.AddRun(nbsp.ToString());
}
}
}
Workaround:
IEnumerable<Table> tables = this.document.EnumerateChildrenOfType<Table>();
foreach (Table table in tables)
{
table.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Auto);
}
IEnumerable<Paragraph> paragraphs = this.document.EnumerateChildrenOfType<Paragraph>();
foreach (Paragraph paragraph in paragraphs)
{
paragraph.Spacing.SpacingAfter = 0;
}
Special chars (åäö) with PdfFormatProvider wont work.
Project submitted!
public void SpecialCharsTest()
{
RadFlowDocument document = new RadFlowDocument();
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
editor.InsertText("Before text");
editor.InsertText("åäö ÅÄÖ ☕"); // This line will not appear in the pdf
editor.InsertText("After text");
using (Stream output = new FileStream("specialCharTest.pdf", FileMode.OpenOrCreate))
{
PdfFormatProvider provider = new PdfFormatProvider();
provider.Export(document, output);
}
}Special characters wont work :-/
Example: background-color: rgb(197,93,161);
