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();
                    }
                }

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).

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();

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.

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.

Release R1 2020 SP1 (LIB 2020.1.210)

I have a RadRichTextEditor. When it contains multiple lines a vertical scroll bar is shown. When I keep writing and press the enter key to insert a carriage return, it starts a new paragraph but the cursor disappears. 

When I press return at the bottom of this control I want the cursor to be kept in sight. See the screenshots I have attached. You can see that after the return you can only see the very top of the cursor, the rest is hidden. You have to actually manually scroll down to get it into view.

When you start typing, this cursor comes into view, but I want it to be in view even if you just press return. Is there a way to get it to do this?

This seems to be the default behavior of this control, as I have created a new application to show this, which doesn't contain any of the formatting which my actual application does.

Please refer to the attached gif file illustrating better how to replicate the undesired behavior.

1. If you right-click, the Copy and Cut context menu items are disabled - OK

2. If you select some text and right-click, the Copy and Cut context menu items are enabled - OK.

3. If you select some text and right-click very fast, sometimes Copy and Cut are disabled. Even there is cases in which Cut is enabled and Copy is disabled. 

Workaround: please ensure that you select the text first and then right-click to trigger the context menu.
