Hey,

I'm creating a dialog to give the user a visual way to create relationships between data. To do this I have programmatically created 2 tableNode objects and set the TableConnectionStyle to be Rows - essentially working the same way as the Database Design sample works.

My questions are regarding the validation of what the user has done. Is there an easy way to detect (at LinkCreating, ideally) whether a link already exists between the origin row and destination row.... I can get it to detect links between the nodes, which should allow multiple, but a row should only connect to one other row. Also, is there an easy way to collect the data at the end so i can see which rows connect to which? The OutgoingLinks and IncomingLinks lists for the tableNodes are empty...? I'm probably missing something obvious. 

Thanks,
Rich

For the second question - links between table rows are accessible via the rows own OutgoingLinks and IncomingLinks collections, so you should check if there is an already existing link from originTable.Rows[originIndex].OutgoingLinks to destTable.Rows[destIndex].IncomingLinks.

I hope that helps,
Stoyan
