Hi, no problem, the idea is to publish a different field with all your repeating value concatenante on this field. You have to use your own Xpath. You can use this code on publish for exemple.
// Retrieve the rows of the repeating table
XPathNavigator root = MainDataSource.CreateNavigator();
XPathNodeIterator rows = root.Select("/my:myFields/my:rows/my:row", NamespaceManager);
string title="";
// Loop through the rows of the repeating table
while (rows.MoveNext())
{
// Retrieve the title
title += rows.Current.SelectSingleNode("my:title", NamespaceManager).Value+ ";";
}
//set another field with Title value
root.SelectSingleNode("/my:myFields/my:Other_row", NamespaceManager).SetValue(title)
On my sample you have to publish Other_row on Sharepoint.
Hope it's help!
