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.

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);
    }
}

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);

Invalid document is generated when track changes is enabled and the InsertFragment method is used

While typing, there are spaces added after the content, the caret is not positioned as expected.

The document content is not measured properly, leading to incorrect selection ranges.

Currently, the address tag is not supported and everything within this tag is skipped on import.

RichTextBox: Replacing text in a hyperlink puts the text with a wrong start position. It starts from the second index.

When importing an HTML file which contains table should align table cell content left and middle. Instead, it aligns them left and top.

With the current implementation, each change in a Table's structure invalidates the styling of all the cells in it when conditional styling is applied. This leads to re-rendering the whole table and affects the performance. If adding rows at the end of the table, only the new row can be styled. Another option is to expose API to allow the customers to disable the styling update while inserting rows and enable it after they are ready with the insertion.

Xaml exported in Net Core app cannot be imported with Net Framework app

This behavior is observed when copy and paste a Chinese text wrapped in a bookmark.

Steps to reproduce:
1. Import the attached document (testDocument.docx)

The table merge and columns width are not correct when importing a specific document

Keys in Traditional Chinese On-screen Keyboard are duplicated.

Hello,

   We found a problem when using the radrichtextbox control. When radrichtextbox is enabled to cancel input, error will be reported using the sougou Chinese input method. This problem will not occur in the English input method. Please help solve it. Thank you very much.

This functionality is supported by MS Word: 

A possible workaround could be to enclose the RadSpreadsheet as a UI element. More information could be found in the InlineUIContainer help article.

Memory leak caused by the section columns dialog

Currently, when importing an RTF document that does not conform to RTF syntax an exception is thrown.

Telerik.Windows.Documents.FormatProviders.Rtf.Exceptions.RtfUnexpectedElementException: 'Exception of type 'Telerik.Windows.Documents.FormatProviders.Rtf.Exceptions.RtfUnexpectedElementException' was thrown.'

The DeepCopy method does not copy the font of the predefined table styles

 

Workaround:

When the copied text doesn't contain any formating the Keep Text Only paste option should be applied (check the attached record.gif)
