I have used a data-set to RDLC report and data set get Connection String from web Config File. Since all the other data Forms Got Connection from XML file. So I want to set my Dataset Connection to that XML. Is it possible to change dataset XSD connection to a Class Method that retrieve data from XML?

Example DB connection Class

public String get Connection ()
{
    return Con;
}

So can I set to RDLC dataset to that Method to retrieve Connection String??
