Find & Iterate over Tables in Richtextbox

Question

I didn't know it would be so difficult to play with Richtextbox control. I am trying to fetch Clipboard data and trying to set in a RichTextBox.

RichTextBox rtb = new RichTextBox();
rtb.Rtf = Clipboard.GetText(TextDataFormat.Rtf);

How to iterate over table collection or Indivisual tables ? Can we find table count from RichTextBox ?

My goal is to find if there are any table in the clipboard RTF data and if yes then check those for data in it.

Yep, not easy. You will have to examine the rtf codes themselves. Things like `\trowd`, etc. In my experience, rtf doesn't really have a concept of "tables", it's more like, rows of cells. — LarsTech, Jun 21 '13 at 14:24
@LarsTech- guess i will have to go with some unorthodox ways. for ex. if rtf data has a word `trowd`, that means it definitely has some rows in it. — Sangram Nandkhile, Jun 21 '13 at 18:04
This surely requires you to work with some kind of `RTF Parser`, you may want to search for a library or write a one (just handling with Table structure) yourself. In case you would like to write your own one, I think using `Regular Expression` is the best choice to parse the Table structure, of course you should refer some document on `RTF` structure to know its syntax, especially syntax on Table. I think this is not easy, but must be very interesting :) — King King, Jun 21 '13 at 20:55
@Sangram you may want to Bing (not Goolge :) for more, I've found these documentation which should be helpful: http://www.biblioscape.com/rtf15_spec.htm and the newer version: https://www.google.com.vn/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&sqi=2&ved=0CDoQFjAC&url=http%3A%2F%2Frepositorium.googlecode.com%2Fsvn%2Ftrunk%2FRtfConverter%2FWord2007RTFSpec9.pdf&ei=iO7GUaCvCoKEiAe604H4CQ&usg=AFQjCNEodEHav3SHNTMGTa9JaTsi5SBv_w&sig2=TVDJyX3xyvpnTlj1druWeA&bvm=bv.48293060,d.aGc I think you may have to work hard with it if you don't have much time. — King King, Jun 23 '13 at 12:51
You may use the table format in rtf: http://stackoverflow.com/questions/8349827/using-tables-in-rtf/13321729#13321729 — Jerry, Jun 29 '13 at 02:40

Although, its bit too late to answer this question. I also came across same requirement.this way i proceeded:

private static void findTableinRtf(string rtf)
    {
        var flowDocument = new FlowDocument();
        var textRange = new TextRange(flowDocument.ContentStart, flowDocument.ContentEnd);
        using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(rtf)))
        {
            textRange.Load(ms, DataFormats.Rtf);
        }
        var blocks = flowDocument.Blocks;
        foreach (var block in flowDocument.Blocks)
        {
            switch (block)
            {
                case List list:
                     //implement List;
                    break;

                case Table table:
                    workWithTable(table);
                    break;

                case Paragraph paragraph:
                    convertParagraph(paragraph);
                    break;
                case Section section:
                    convertSection(section);
                    break;

            }
        }

    }
    private static void workWithTable(Table rtfTable)
    {
        TableColumnCollection columns = rtfTable.Columns;
        TableRowGroupCollection rowGroups = rtfTable.RowGroups;
        foreach (var row in rowGroups[0].Rows)
        {
            //access cells
            // row row.Cells[i];

        }

    }
