I haven't seen anything in the sparse documentation, nor in a forum thread, on the topic of inserting text into a particular table cell.

What I want to know is how to do something that should be very straightforward: get a particular table cell reference and insert formatted text into it.

For example, with this, I create a RadFlowDocument, attach an editor to it, insert a table, then a row, then a cell into the row:

RadFlowDocument document = new RadFlowDocument();
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
var table = editor.InsertTable();
var firstRow = table.Rows.AddTableRow();
var firstCell = firstRow.Cells.AddTableCell();

How do I insert text now?

And actually, more importantly, how would I take a *randomly selected* TableCell from an already constructed document and insert text (and images) into that?

(In case it isn't obvious: for my first question, how do I insert text (or images) into the cell referenced by firstCell?)

Hi Phil,

You should add paragraph to your cell in the table and then add a run in the inline collection. More on that can be found here

As for adding an image you could use the AddImageInline() method.

A sample code for achieving both is shown below:
                  RadFlowDocument document = new RadFlowDocument();
            RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
 
            var table = editor.InsertTable();
            var firstRow = table.Rows.AddTableRow();
            var firstCell = firstRow.Cells.AddTableCell();
            var secondCell = firstRow.Cells.AddTableCell();
            var thirdCell = firstRow.Cells.AddTableCell();
 
            //inserting text in the cell
            firstCell.Blocks.AddParagraph().Inlines.AddRun("text1");
            secondCell.Blocks.AddParagraph().Inlines.AddRun("text2");
 
            //inserting image in the cell
            using (Stream firstImage = File.OpenRead(@"D:\immages\logo.png"))
            {
                var inImage = table.Rows[0].Cells[2].Blocks.AddParagraph().Inlines.AddImageInline();
                inImage.Image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(firstImage, "png");
            }
 
            using (Stream output = new FileStream(@"insertImageAtCell.docx", FileMode.OpenOrCreate))
            {
                DocxFormatProvider provider = new DocxFormatProvider();
                provider.Export(document, output);
            }
Hope this helps.

Hi Peshito,

How about adding a row to existing table from docx template?

I have an existing docx that serves as a template. This file is already formatted with header, footer, text and table with 5 rows and 2 columns. 1st row has merged columns and from row 2 onwards has 2 columns.

Now, how can I reference that existing table and insert row after 3rd row.

Thanks in advance,

RJ

Hello, 

You can edit an existing table by locating the table element first. This can be achieved like this:

IEnumerable<Table> tables = document.EnumerateChildrenOfType<Table>();
var table = tables.FirstOrDefault();            table.Rows.AddTableRow().Cells.AddTableCell().Blocks.AddParagraph().Inlines.AddRun("new run");

Hope this helps.

Regards,

Peshito
