Report not displaying data in Application

[Matthew]

I created a POC report in the designer and it is working properly.  I am now trying to implement this in a WPF application and have the report opening, just showing no data.  (I am up to date using the Q3 2012) assemblies.

The ReportContent is being retrieved from a database.  I am replacing the ConnectionString at runtime and have verified that it is being updated appropriately.  At runtime ConnectionString="" is being updated to a valid connection string.

Also, I am not sure why, but if I do not remove "xmlns="http://schemas.telerik.com/reporting/2012/2" from the XML it will not even display the report and tell me that I have an invalid connection.  Simply removing this at least allows the report to display, just with no data.

Here is a sample of the XML being pulled from the database:

<?xml version="1.0" encoding="utf-8"?>
<Report DataSourceName="TestConn" Width="6.45833333333333in" Name="Parent">
  <DataSources>
    <SqlDataSource ConnectionString="" SelectCommand="SELECT ID, CreateDate FROM tblTest WHERE ID= 1234" Name="TestConn" />
  </DataSources>
