How can users be able to attach text to the link and also to the shapes that they are drawing at runtime?

Is there any way to not let users draw links from /to headers of table?

ConnectionStyle = Rows is wokring only for table caption but it is not working for Header rows.

This is what I have, and e.TableRow is always returning 0 for me(is it bug) irrelavent of which row I am creating the link.

void onLinkCreating(object sender, LinkValidationEventArgs e)

{
if (e.Node.GetType().Name == "TableNode")
{
if (((TableNode)e.Node).Rows[e.TableRow].Header == true)
e.Cancel = true;
}
}

I have header in my zero row so it is not letting me draw links from one table to the other irrelevant of any row but it is letting me draw links to any other shape.

My point is it is firing that onLinkCreating method couple of times, for source and destination so is it going to combine all decisions for cancelling? or it is just taking the validation alone?

While the user is still drawing a link, the result of the Creating event affects just the mouse cursor, showing whether the operation would be accepted. The Creating event is raised for one last time when the user releases the mouse button, and setting Cancel = true then cancels the operation.

Check if (e.Origin as TableNode)[e.Link.OriginIndex].Header is enabled to find out whether the user started drawing from a header row. I suppose in that case it's best to call e.CancelDrag() to stop the operation immediately.

I hope that helps,
