Please refer to the attached IncorrectImageResizing.gif illustrating how to reproduce the problem with the Demo application.

Workaround: feel free to resize the image via the mouse cursor.

How to reproduce:  set the page view in backstage, add a page item and set its text to be very long

Workaround: use the custom theme

To reproduce: try to hide the caret: 
this.radRichTextEditor1.CaretWidth = 0;

Workaround:

//Flow layout
this.radRichTextEditor1.LayoutMode = DocumentLayoutMode.Flow;
Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter webLayoutPresenter =
    this.radRichTextEditor1.RichTextBoxElement.ActiveEditorPresenter as Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter;
webLayoutPresenter.Caret.Width = 0;

//Page layout
this.radRichTextEditor1.LayoutMode = DocumentLayoutMode.Paged;
Telerik.WinControls.RichTextEditor.UI.DocumentPrintLayoutPresenter activeEditorPresenter1 = 
    this.radRichTextEditor1.RichTextBoxElement.ActiveEditorPresenter as DocumentPrintLayoutPresenter;
activeEditorPresenter1.Caret.Width = 0;

To reproduce: please refer to the attached sample project. You will notice that the exported HTML content from the left RadRichTextEditor is imported to the right and the bullets are not the same.

Hi Team,

 We find out another issue in the RichTextEditor about the Header and Footer Section of the page, we have a scenario in which we have a bigger table in the Footer section in terms of height, and the table going just "Out Of the Box". I tried the same table in the header section I found a similar behavior there also but the major issue is the Footer section where it's going out of the page.

I used the demo Winform application to reproduce this, I am also attaching the source file so you have to open it in the editor on your side to reproduce this issue.

 

Regards

Workaround: 
private void ClearDictionaries(RadRichTextEditor editor)
{
    var dictionaries = typeof(DocumentSpellChecker).GetField("dictionaries", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(editor.SpellChecker) as Dictionary<CultureInfo, Lazy<IWordDictionary>>;
    dictionaries.Clear();
    var customDictionaries = typeof(DocumentSpellChecker).GetField("customDictionaries", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(editor.SpellChecker) as Dictionary<CultureInfo, ICustomWordDictionary>;
    customDictionaries.Clear();
}

How to reproduce: check the attached video

Workaround: 
public partial class Form1 : Form
{
    private RadButtonElement buttonHeader;
    private RadButtonElement buttonFooter; 

    public Form1()
    {
        InitializeComponent();

        this.buttonHeader = (RadButtonElement)this.richTextEditorRibbonBar1.GetType().GetField("buttonHeader", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(this.richTextEditorRibbonBar1);
        this.buttonFooter = (RadButtonElement)this.richTextEditorRibbonBar1.GetType().GetField("buttonFooter", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(this.richTextEditorRibbonBar1);
        
        this.radRichTextEditor1.RichTextBoxElement.IsInHeaderFooterEditModeChanged += RichTextBoxElement_IsInHeaderFooterEditModeChanged;
    }
    
    private void RichTextBoxElement_IsInHeaderFooterEditModeChanged(object sender, EventArgs e)
    {
        if (!this.radRichTextEditor1.RichTextBoxElement.IsInHeaderFooterEditMode)
        {
            this.buttonHeader.Enabled = true;
            this.buttonFooter.Enabled = true;
        }
        else
        {
            this.buttonHeader.Enabled = false;
            this.buttonFooter.Enabled = false;
        }
    }
}

To reproduce:
- Click the InsertMergeFiled button before setting the data source.
- Set the data source.
- Click the button again.
- There are no items in it.
 

Workaround:
Friend Class MyRichTextEditorRibbonBar
    Inherits RichTextEditorRibbonBar



    Protected Overrides Sub dropDownButtonInsertMergeField_DropDownOpening(sender As Object, e As CancelEventArgs)
        MyBase.dropDownButtonInsertMergeField_DropDownOpening(sender, e)
        If Me.dropDownButtonInsertMergeField.Items.Count = 0 Then
            Me.dropDownButtonInsertMergeField.Items.Add(New RadItem)
        End If
    End Sub

End Class

To reproduce: 

• Add a table and select 3 rows.
• From the context menu select Delete Row
• Only one row is deleted

The attached video shows how you can reproduce this.

To reproduce: 
Please refer to the attached sample application and video demonstrating the experience issue. 

Workaround: 
Set RadRichTextEditor to null in Form`s Dispose method: 
Protected Overrides Sub Dispose(ByVal disposing As Boolean)
    Me.RadRichTextEditor1 = Nothing
    Try
        If disposing AndAlso components IsNot Nothing Then
            components.Dispose()
        End If
    Finally
        MyBase.Dispose(disposing)
    End Try
End Sub

When changing the theme to a dark theme the Rich text editor appears to have an issue converting the Styles tab as below. Expected to see conversion from light theme styles to dark themes styles.

To reproduce:

private void radButton1_Click(object sender, EventArgs e)
{
    var document = new RadDocument(); 
    var section = new Section();
    document.Sections.Add(section);
    var paragraph = new Paragraph();
    section.Blocks.Add(paragraph);
    var span = new Span("BOLD");
    span.FontWeight = FontWeights.Bold;
    paragraph.Inlines.Add(span);

    span = new Span(" REGULAR");
    paragraph.Inlines.Add(span);

    editor.Document = document;

    var pdfExporter = new PdfFormatProvider();
    var path = Path.GetTempFileName() + ".pdf";
    using (var file = File.Create(path))
    {
        pdfExporter.Export(document, file);
        file.Flush();
        file.Close();
        
    }
    Process.Start(path);
}

Workaround: export .docx file and use the RadWordsProcessing library to import the .doc file and export it to pdf:

private void radButton1_Click(object sender, EventArgs e)
{
    var document = new RadDocument();
    var section = new Section();
    document.Sections.Add(section);
    var paragraph = new Paragraph();
    section.Blocks.Add(paragraph);
    var span = new Span("BOLD");
    span.FontWeight = FontWeights.Bold;
    paragraph.Inlines.Add(span);

    span = new Span(" REGULAR");
    paragraph.Inlines.Add(span);

    editor.Document = document;

    var wordExporter = new Telerik.WinForms.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
    var wordPath = Path.GetTempFileName() + ".doc";
    using (var file = File.Create(wordPath))
    {
        wordExporter.Export(document, file);
        file.Flush();
        file.Close();
    }

    Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider provider =
        new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
    using (Stream input = File.OpenRead(wordPath))
    {
        Telerik.Windows.Documents.Flow.Model.RadFlowDocument doc = provider.Import(input);

        Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider pdfProvider =
            new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
        string filePath = @"..\..\" + DateTime.Now.ToLongTimeString().Replace(":", "-");
        using (var output = File.Create(filePath))
        {
            pdfProvider.Export(doc, output);
        }
        Process.Start(filePath);
    }
}

To reproduce:
1 Please change the font via selection list first.
2 Set text cursor to font input field and select the whole text (if not already done).
3 Press backspace or delete key.
4 An error message appears.

Workaround:
protected override void DropDownListFont_SelectedIndexChanged(object sender, PositionChangedEventArgs e)
{
    var ddl = sender as RadDropDownListElement;
    if (ddl.SelectedItem != null)
    {
        base.DropDownListFont_SelectedIndexChanged(sender, e);
    }
}

To reproduce:
- Open a document that contains symbols with the 2015 Q3 SP1 version.
- Export the document using the docx format.
- Open it again.

Workaround:
private void radRichTextEditor1_DocumentChanged(object sender, EventArgs e)
{
    this.SelectAllMatches("");
    this.radRichTextEditor1.ChangeFontFamily(new Telerik.WinControls.RichTextEditor.UI.FontFamily("Symbol"));
    this.SelectAllMatches("");
    this.radRichTextEditor1.ChangeFontFamily(new Telerik.WinControls.RichTextEditor.UI.FontFamily("Symbol"));
}
 
private void SelectAllMatches(string toSearch)
{
    this.radRichTextEditor1.Document.Selection.Clear();
    DocumentTextSearch search = new DocumentTextSearch(this.radRichTextEditor1.Document);
    foreach (var textRange in search.FindAll(toSearch))
    {
        this.radRichTextEditor1.Document.Selection.AddSelectionStart(textRange.StartPosition);
        this.radRichTextEditor1.Document.Selection.AddSelectionEnd(textRange.EndPosition);
    }
}

I just updated from 2021.1.326 to 2021.2.615 and suddenly the app hangs and eventually crashes.

To reproduce:
- Add some text and change its forecolor.
- Add more text and change its highlighting
- Save as rtf and open it in WordPad.
