Hi,

I am trying to create infopath form, which will load the repeating control with data at run time.

This is the code that i am using at Form Load event

XPathNavigator xn = this.MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:group1", this.NamespaceManager);

XPathNavigator firstNode = xn.SelectSingleNode("/my:myFields/my:group1/my:group2[1]", this.NamespaceManager);

XPathNavigator lastNode = xn.SelectSingleNode("/my:myFields/my:group1/my:group2[" + 1 + "]", this.NamespaceManager);

firstNode.DeleteRange(lastNode);

                foreach (DataRow row in dsProject.Tables[0].Rows)
                {
                    xn.SelectSingleNode("/my:myFields/my:group1", this.NamespaceManager).AppendChild("<my:group2><my:f_ProjectId>" + row["ProjectId"].ToString() + "</my:f_ProjectId><my:f_ProjectName>" + row["ProjectName"].ToString() + "</my:f_ProjectName><my:f_ProjectDescription>" + row["Description"].ToString() + "</my:f_ProjectDescription></my:group2>");

                }

when i click preview... It is working fine.

But when i try to show this form in XmlFormViewer in share point it is showing "An error occurred accessing a data source."

Can any one help me to solve this problem..

Thanks,

Code
