When the copied document fragment is replaced during paste within a single RadDocument:
ClipboardEx.SetDocument(new DocumentFragment(doc));Ordered list are not pasted correctly.
Workaround:
Bypass paste and use the InsertFragment API
this.radRichTextBox.InsertFragment(new DocumentFragment(doc)); e.Cancel = true;
Use the attached project to reproduce:
- Click the first button so the image is changed
- Click the second button and examine the exported HTML
Expected: the Uri is exported
Actual: the Uri is not exported.
Workaround:
p.Inlines.AddAfter(image, image2);p.Inlines.Remove(image);
When the MEF catalog of RadRichTextBox is predefined, the PasteOptionsPopup is not automatically loaded and causes NullReferenceException in the presenter when the users press Ctrl or Esc.
Workaround: Add typeof(PasteOptionsPopup) to the catalog.
The document styles are not respected because of wrongly imported custom style name after copy-paste from MS Word and exported to HTML.
Workaround: avoid using styles with braces in their name.
To reproduce:
- Select several words by holding the control key.
- Paste some text.
Result: the first word is replaced, the other are deleted
Expected: the text should be pasted in all selected places
Workaround:
private void RadRichTextBox_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e){
if (e.Command is PasteCommand)
{
var ranges = radRichTextBox.Document.Selection.Ranges.ToList();
if (ranges.Count > 1)
{
e.Cancel = true;
foreach (var range in ranges)
{
radRichTextBox.Document.Selection.Clear();
radRichTextBox.Document.Selection.AddSelectionStart(range.StartPosition);
radRichTextBox.Document.Selection.AddSelectionEnd(range.EndPosition);
PasteNewText();
}
}
}
}
public void PasteNewText()
{
DocumentFragment clipboardDocument = null;
string clipboardText = null;
bool clipboardContainsData = false;
if (ClipboardEx.ContainsText(null))
{
clipboardText = ClipboardEx.GetText(null);
clipboardContainsData = true;
}
if (!clipboardContainsData)
{
return;
}
if (clipboardDocument != null)
{
this.radRichTextBox.ActiveDocumentEditor.InsertFragment(clipboardDocument);
}
else if (!string.IsNullOrEmpty(clipboardText))
{
this.radRichTextBox.ActiveDocumentEditor.Insert(clipboardText);
}
}
To reproduce:
- Hold the control key and double click a word
Actual: the entire paragraph is selected
Expected: the current word should be selected, the existing selection should be extended.
Moreover, is specific cases when the style of the name ends with specific symbols which are not allowed for element names in XML/HTML, e.g. "Heading1?", an ArgumentException is thrown.
As suggested in the orginal support ticket 1430154 I'm opening a separate bug reprot for the RadRichTextBox.
Visual Studio 2019 solution to reproduce the problem is attached to the bug report.
Workaround: Ensure the document is measured before assigning it to RadRichTextBox.
To reproduce:
- Create two lists one after another
- Select the second by using the keyboard
- Press delete and then Ctrl+z (undo)
This works fine when the list is selected with the mouse.
To reproduce:
- Add a multilevel list to a document and export it to HTML
- Import the document again the list is changed and the values are not correct.
Example:
Importing padding: 5px; style is imported as padding-top: 5px, padding-right: 0px, padding-bottom: 0px, padding-left: 0px
Padding syntax can be seen in the specification.
Workaround: Apply padding values for all four sides.
Incorrect behavior when setting the table cells padding
Steps to reproduce:
- Insert a table
- Open Table Properties
- Clear the value in the "Left" field
- Check "Same for all sides"
- Click OK
When trying to import a document containing bookmark and BookmarkRangeEnd is after the last paragraph, a StackOverflowException is thrown in IntervalNode while trying to rebuild the document cache. (RadDocumentChildrenCache.RebuildTree()).
The same could be observed if the bookmark end is last in the header/footer, between table cells in the RadDocument body, or when all paragraphs after the bookmark range end are hidden (with vanish property).
Workaround: Detect the problematic annotations and remove them:
foreach (var rangeStart in document.EnumerateChildrenOfType<AnnotationRangeStart>())
{
if (rangeStart.End == null || rangeStart.End.Parent == null || rangeStart.End.Parent.Parent == null)
{
//MessageBox.Show("This indicates a problem.");
rangeStart.Parent.Children.Remove(rangeStart);
}
}
Note: Until 2017 R2 SP1 release StackOverflowException is thrown, after this release an ArgumentException should be thrown.
