"http://" prefix is automatically added by the Insert Hyperlink Dialog when the provided URI is to local path or mapped drive, e.g. "Z:\temp".

Workaround 1: Set HyperlinkPattern to something that matches file paths, e.g.:
(this.radRichTextEditor1.RichTextBoxElement.InsertHyperlinkDialog as InsertHyperlinkDialog).HyperlinkPattern = ".*";

Workaround 2: Insert such paths with the "file://" prefix.

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;
                        }
                    }
                }

in new update with rich text editor has new property called  MentionBox settings of that auto added in to designer code. 

which creates an error when we run the application.

following line is auto added.

mentionBox1.FocusedItemIndex = -1;

 

we have to comment every time after doing UI changes. and we need to check every time whether that line is commented or not. 

 

Please Help Us.

Add only a RichTextEditorRibbonBar without any other control on the form. If you run the application you will notice that it loads more than one second. We should investigate if it is possible and how to improve the initialization time.
