Hi,

I have been using the following to add rows to a repeating table:

XmlDocument doc = new XmlDocument();
XmlNode group = doc.CreateElement("group2", NamespaceManager.LookupNamespace("my"));

XmlNode field = doc.CreateElement("field1", NamespaceManager.LookupNamespace("my"));
XmlNode node = group.AppendChild(field);
node.InnerText = "Cell 1";

field = doc.CreateElement("field2", NamespaceManager.LookupNamespace("my"));
node = group.AppendChild(field);
node.InnerText = "Cell 2";

field = doc.CreateElement("field3", NamespaceManager.LookupNamespace("my"));
node = group.AppendChild(field);
node.InnerText = "Cell 3";

doc.AppendChild(group);

MainDataSource.CreateNavigator().SelectSingleNode(
"/my:myFields/my:group1",
NamespaceManager).AppendChild(doc.DocumentElement.CreateNavigator());
 

However Cell 3 is no longer a text field, but is a button.  Thus, I need to add a row, fill in the values for the first
two columns, and somehow get a button to appear.  I tried cloning an existing 
row, which works nicely, but I can't seem to get ahold of the row and put values in the fields.

Any help would be much appreciated. 

Thanks in Advance.

 What happens if you remove this part?:

field = doc.CreateElement("field3", NamespaceManager.LookupNamespace("my"));
node = group.AppendChild(field);
node.InnerText = "Cell 3";

The button is part of the repeating table control. It's not something you manually add to each row from the code.
