Positioning Cursor in Rich Text Box

[BruceQ]

                var textRangeAll = search.FindAll("\\[");

                foreach (var textRange in textRangeAll)

                {

                    if (textRange != null)

                    {

                        DocumentPosition startB = textRange.StartPosition;

                        DocumentPosition endB = textRange.EndPosition;

                        var spaceRange = search.Find("[ ;.,]", startB);                            

                           …

                     }
                }

The code above will find all open brackets in a rich text box and loop through them.  In the loop we then find the next space, semicolon, period or comma starting in the position of the open bracket.

I need to change this to start the find for [ ;.,] two characters AFTER the open bracket.  In other words I need to change startB DocumentPosition variable to two characters after the open bracket.

How can I do this?

Hello Bruce,

Thank you for contacting us about this issue!

In order to move the DocumentPosition with a single position you can use MoveToNext() method. You may notice that this method returns a boolean indicating whether the move was successful (if there was a valid position to move to).

Here is some sample code which should solve the issue you are facing:

RadDocument document = this.radRichTextBox.Document;
DocumentTextSearch search = new DocumentTextSearch(document);

IEnumerable<TextRange> textRangeAll = search.FindAll("\\[");
foreach (var textRange in textRangeAll)
{
    if (textRange != null)
    {
            DocumentPosition startB = textRange.StartPosition;

            //Moving as many positions as you need.
            startB.MoveToNext();
            startB.MoveToNext();

            TextRange spaceRange = search.Find("[ ;.,]", startB);

            //Use the found item here! For example adding it to selection.
            spaceRange.AddToSelection(document);
    }
}
