Hi, 

Based on a Selection, I would like to add a comment. 

I was wondering how i would do this within the code. 

So i have my selection:
this.editor.Document.Selection // I would like to add my comment for this selection. 

An example for doing this would be great. 

Thanks

I have tried this:

Comment comment = new Comment(commentmessage);
DocumentPosition startPosition = RadRichTextDocument.Document.Selection.Ranges.First.StartPosition;
DocumentPosition endPosition =  RadRichTextDocument.Document.Selection.Ranges.First.EndPosition; 
RadRichTextDocument.Document.InsertComment(startPosition, endPosition, comment);
RadRichTextDocument.UpdateLayout();
But nothing seems to happen... Is there anything i'm missing out?

Answer to my question:

RadRichTextDocument.ShowComments = true; // I WAS MISSING THIS OUT!!!
 
			DocumentPosition startPosition = RadRichTextDocument.Document.CaretPosition;
			DocumentPosition endPosition = new DocumentPosition(startPosition);
 
			startPosition.MoveToFirstPositionInParagraph();
			endPosition.MoveToLastPositionInParagraph();
 
			RadRichTextDocument.Document.InsertComment(startPosition, endPosition, new Comment(commentmessage));

Hi, I have managed to delete all the comments in the document using:

CommentRangeStart[] cR= RadRichTextDocument.Document.EnumerateChildrenOfType<CommentRangeStart>().ToArray();
   for (int i = 0; i < cR.Length; i++)
			{
				CommentRangeStart currentC = cR[i];
			 	start.MoveToInline(currentC.FirstLayoutBox as InlineLayoutBox, 0);
			 	end.MoveToInline(currentC.End.FirstLayoutBox as InlineLayoutBox, 0);
				end.MoveToNextInline();
 
				RadRichTextDocument.DeleteComment(currentComment);
			}

But I want to delete a comment which is within the currently selected text, how would i go about doing this? 

Thanks

Hello Chez,

You can get the boxes in the selection and remove all comments like this:

if (!this.editor.Document.Selection.IsEmpty)
{
    IEnumerable<InlineLayoutBox> selectedBoxes = this.editor.Document.Selection.GetSelectedBoxes().ToList<InlineLayoutBox>();
    foreach (InlineLayoutBox inlineBox in selectedBoxes)
    {
        if (inlineBox.AssociatedInline is CommentRangeStart)
        {
            this.editor.DeleteComment((CommentRangeStart)inlineBox.AssociatedInline);
        }
    }
}

In this way, all comments that have their start within the selection will be removed. You can further customize this solution to check if the CommentRangeEnd is within the selection instead of CommentRangeStart or check if both the start and end of the comment are within the selection.

However, you should have in mind that each delete operation will be registered separately in the history stack and undo/redo will add/remove only one comment at a time. I hope this helps.
