In Word, for paragraphs in a list:

1. The bullet/number uses the value of the first line indent

2.1 The text on the first line is aligned according to the left indent when the left indent is smaller than the first line indent (the usual case).

2.2 If the first line indent is smaller than the left indent, the first line aligns with the rest of the text, using the value of the left indent property.

2.3 When there are tab stops, they are used for the position of the text. In RadRichTextBox, the text in the first line always aligns according to the FirstLine indent.

Also, tab stops can be used to position the text after the bullet/number.

Add Paragraph property controlling  whether SpacingBefore / SpacingAfter is applied between paragraphs with the same style.

In MS Word, the corresponding option is controlled with "Don't add space between paragraphs of the same style" checkbox in the font properties dialog - and the paragraph spacing after will not be applied. 

In OOXML, it is described with the w:contextualSpacing element. We don't respect this property on import of such files, and the paragraph spacing is bigger.

Common use case for this feature is that when list is applied to multiple paragraphs, Paragraph List style is applied to the items, and this style has "Don't add space between paragraphs of the same style" applied, so the vertical spacing between the items is smaller.

The tab order in the dialog is incorrect, the dialog is not focused when shown.

Workaround: 

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        radRichTextEditor1.RichTextBoxElement.FindReplaceDialog = new MyFindReplaceDialog();

    }
}
class MyFindReplaceDialog : FindReplaceDialog
{
    public MyFindReplaceDialog()
    {
        this.Controls[0].TabIndex = 2; // FindNext button
        this.Controls[1].TabIndex = 3; // Replace Button
        this.Controls[2].TabIndex = 5; // CloseButton
        this.Controls[3].TabIndex = 4; // Replace All button
        //this.Controls[4].TabIndex = 5; // label
        //this.Controls[5].TabIndex = 5; // label
        this.Controls[6].TabIndex = 1; // RepalceWith textbox
        this.Controls[7].TabIndex = 0; // TextToFind  textbox
         

    }
    protected override void OnShown(EventArgs e)
    {
        base.OnShown(e);
        this.Controls[7].Focus();
    }
}

Create different options for pasting (keep formatting, merge formatting, use destination styles). At this point, the document default styles are not copied in the document fragment, thus their loss is observed. 

Loss of formatting is also observed when:
- copying from RadRichTextBox and pasting in Word
- copying from RadRichTextBox and pasting in RadRichTextBox in another process.
- copying from Word and pasting in RadRichTextBox

When deleting all content (e.g. Select All [CTRL+A] + Delete [Del]) in the document, it would be convenient for the user to preserve all formatting (local span formatting + local paragraph formatting + style) applied on the last paragraph. 

This will ensure that the user will continue edit the document with last current font, font family, etc.

If this operation is applied on an empty document, though, the styling of the single paragraph should be reset to the defaults for the document.

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.

Dear Sir/Madam,

 

I have a docx document and want to display it in flow layoutmode. It works normally except it cannot show header at the beginning of the document and footer at the end of the document. Please help.

My code is similar as follows (Rte is the RadRichTextEditor control):

 

DocumentFormatProviderBase provider = new DocxFormatProvider();

Rte.SuspendLayout();

Rte.Document = provider.Import([Docx in byte array]);

Rte.RichTextBoxElement.BackColor = Color.White;

Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter presenter = (Telerik.WinControls.RichTextEditor.UI.DocumentWebLayoutPresenter)rte.RichTextBoxElement.ActiveEditorPresenter;

presenter.BackColor = Color.White;

presenter.Margin = new Padding(20);

Rte.ResumeLayout();

Rte.PerformLayout(); 

To reproduce:

Type a word and then change the font. The RichTextEditor is not focused. When you click in it the font is restored.

Workaround: 
class MyRichtTextEditorRibbonbar : RichTextEditorRibbonBar
{
    public MyRichtTextEditorRibbonbar()
    {
        this.dropDownListFont.PopupClosed += DropDownListFont_PopupClosed;
    }

    private void DropDownListFont_PopupClosed(object sender, RadPopupClosedEventArgs args)
    {
        this.associatedRichTextEditor.Focus();
    }

  
}

1. Document created via MS-Word, Page orientation is set to Landscape. (MS-Word works OK)

2. Document read into Telerik RichTextEditor and print ignore Landscape settings.

3. Documet "Landscape.rtf" and snapshot in attachmet 

please help me 

The dialog should match the strings contained in the different document parts (headers, footers, footnotes, endnotes, comments).

Hello Telerik, 

your control changed the format to Verdana when import rtf. But only in the first line. And only the first line is Arial. Is the first line with any other font formated, its all ok.

Here the code:

string rtfText = @"{\rtf1\ansi\ansicpg1252\deff0\deflang1031{\fonttbl{\f0\fnil\fcharset0 Arial;}{\f1\fnil\fcharset0 Tahoma;}{\f2\fnil\fcharset0 Times New Roman;}{\f3\fnil\fcharset0 Arial Unicode MS;}{\f4\fnil\fcharset0 Calibri;}}
{\colortbl ;\red0\green0\blue0;}
\viewkind4\uc1\pard\tx300\tx600\tx900\tx1200\tx1500\tx1800\tx2100\tx2400\tx2700\tx3000\tx3300\tx3600\tx3900\tx4200\tx4500\cf1\b\fs32 Arial\f1\par
Tahoma\par
\f2 Times New Roman\par
\f0 Arial\f2\par
\f3 Arial Unicode MS\par
\f4 Calibri\b0\f0\fs20\par
}";
RtfFormatProvider rtf = new RtfFormatProvider();
this.radRichTextEditor1.Document = rtf.Import(rtfText);

this.richTextBox1.Rtf = rtfText;

In the screenshot you can see, left the standard .net rtf control and rigth the Telerik richtexteditor. 
The zip is the sample project.

Please refer to the attached gif file.

Let's take for instance demo application with its default document, with text "RadRichTextEditor for WinForms" at the beginning in font Calibri of size 28. Suppose the user wants to add A, then empty line, then C in single line, followed by the rest of the document, and to have these three new lines in Times New Roman in size 10.

If there is no empty line, but letter B in middle line, then user can set caret to document start, set the font and size, and type A<Return>B<Return>C<Return>. And it would look fine (and even then, if we set caret just after B and press Return the new paragraph will have spacing after set to 7.5 for no apparent reason).

If we want an empty line instead of B in the line, then there is no simple way to do it. Typing A<Return><Return>C<Return> would produce a huge gap between A and C (we still first set the caret, and font and size). One way to accomplish what we want is to select all new text, set font size to something other than 10, and then back to 10 (which is also weird to have to do).

In R2 2019 RichTextEditor has a new GUI element, a toggle button named Simplified Ribbon. It looks neat, and I like it, but now I have to localize it. There is a link to a strings file on page https://docs.telerik.com/devtools/winforms/controls/richtexteditor/localization , but I can't find the text "simplified ribbon" in that xml file.

My fallback plan is to download the whole Telerik source code, I'm just reminding you here to update the file. And to ask you to update the file together with Telerik update in the future.

The approach as per the following documentation article is not working: https://docs.telerik.com/devtools/winforms/controls/richtexteditor/features/custom-fonts

To reproduce: run the Demo application >> RichTextEditor >> First Look example and follow the steps illustrated in the attached gif file. 

1. First add a footnote in the text
2. Than select a part of the footnote text or all text and use the context menu to cut the text
3. Then,  paste the text in the document, it doesn't matter were.
4. Next step is to remove the footnote reference.
5.Then, scroll through the document and press the right mouse button to open the context menu.

The object release should have been called and the context menu is disposed. If so the error occurs.

Workaround:

this.radRichTextEditor1.MouseClick += radRichTextEditor1_MouseClick;

        private void radRichTextEditor1_MouseClick(object sender, MouseEventArgs e)
        {
            if (e.Button == System.Windows.Forms.MouseButtons.Right)
            {
                if (this.radRichTextEditor1.RichTextBoxElement.ContextMenu != null)
                {
                    FieldInfo fi = typeof(Telerik.WinControls.RichTextEditor.UI.ContextMenu).GetField("radDropDownMenu", BindingFlags.Instance | BindingFlags.NonPublic);
                    RadDropDownMenu dropdown = fi.GetValue(this.radRichTextEditor1.RichTextBoxElement.ContextMenu) as RadDropDownMenu;
                    if (dropdown.IsDisposed)
                    {
                        this.radRichTextEditor1.RichTextBoxElement.ContextMenu = new Telerik.WinControls.RichTextEditor.UI.ContextMenu();
                    }
                }
            }
        }

The issue only reproduces on Windows 10( 1806). Check the attached video showing the result: 

Workaround: Handle the CommandExecuting event this way
private void RadRichTextEditor1_CommandExecuting(object sender, Telerik.WinForms.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
{
    if (e.Command is ChangeFontFamilyCommand && e.CommandParameter.ToString() == "")
    {
        e.Cancel = true; 
    }
}
