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.

 The scroll is jumping when making a selection and reaching the end of the document (see attached)

When GoToBookmark method is called and the current position is before the bookmark, the screen is not repositioned, causing the bookmark sometimes to appear at the last visible row.

Hello Telerik team,
today I noticed an issue in the Hanling of the RadRichtextEditor,

If the header and footer are resized and then switched between the header and footer views, the following error appears.  (Also in the demo app)

 

System.ArgumentOutOfRangeException: Value of '319' is not valid for 'Value'. 'Value' should be between 'Minimum' and 'Maximum'.

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.

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

Both browsers and MS Word center the content.

When a DOCX document contains a table with fixed layout, and the table contains <tblGrid> element with improper widths (not coinciding with the ones visualized by MS Word), and such document is imported, the table is laid out with the width of the sum of the column widths imported from the table grid (tblGrid), instead of ones that could be correctly computed by the preferred width of the table cells. 

MS Word, for example, may ignore the widths specified in the tblGrid and compute new ones.

As a side effect, fixed-width tables can be laid out longer than their preferred width.

Release R1 2021

The paragraphs in the table are inheriting the negative indent from the previous paragraph.

Workaround: Manually remove the negative indent from the table paragraphs after the table is added.

The workaround in code:

private void RadRichTextEditor1_CommandExecuted(object sender, Telerik.WinForms.Documents.RichTextBoxCommands.CommandExecutedEventArgs e)
{
    if (e.Command is InsertTableCommand)
    {
        var table = radRichTextEditor1.Document.CaretPosition.GetCurrentTable();
       
        table.TableIndent = 0;  
        
        if (table != null)
        {
            foreach (var row in table.Rows)
            {
                foreach (var cell in row.Cells)
                {
                    foreach (var block in cell.Blocks)
                    {
                        var paragrpah = block as Paragraph;
                        if (paragrpah != null && paragrpah.LeftIndent < 0)
                        {
                            paragrpah.LeftIndent = 0;
                            paragrpah.HangingIndent = 0;
                        }
                    }
                }
            }
        }
        radRichTextEditor1.RichTextBoxElement.Document.UpdateLayout();
    }
}

The cell BackColor should be set when setting the paragraph BackColor.

Workaround: use the table properties dialog to set the back color.

Character properties applied on the last paragraph symbol for a paragraph in a list, e.g. font size, are not exported to HTML when StyleExportMode is Inline. 

As a side effect, when the document is imported back, and the text of the bullet is deleted, its properties switch back to the default ones.

Workaround: Change the styles to export as inline properties:
htmlProvider.ExportSettings.StylesExportMode = StylesExportMode.Classes;
 
Please be aware that this may cause side effects, as described in this issue: RichTextBox: Character properties of the paragraph symbol are exported to HTML for the whole list item when StyleExportMode is Classes

To reproduce the problem create new blank Word document (from MS Word). Hold Alt key and type 0268. You will see a letter Č (Latin letter C with caron). In Visual Studio create a Word-inspired project, and run it. Copy the text from Word document to the Telerik RTF editor. Now in Telerik RTF editor change the font of this letter to Algerian. I have Algerian font with my Office 2013, so I hope you'll have it too; you can use Symbol font instead of Algerian for the same result. My Algerian font does not support letter Č, so in Telerik RTF editor I will see a narrow empty box (also called "tofu") instead of letter Č.
