How do I obtain reference to current DataRow from binding?

Question

 

I am trying to make some business rule classes that are part of a collection and sit independent of any datasource, and currently I am making a front end for them that handles datatables.  The question is... is there a way for me to obtain a reference to the current datarow from one of the many binding objects in a binding system.  This way the client programmer will not have to pass a DataRow to me and call "EvaluateRules()", rather I can find out what the current DataRow, or DataRows (in a DataSet) are and go from there.

 

 

Answer 1

Check the Current property of a BindingManagerBase class.

Answer 2

If, for examplo you have a "customersBindingSource" than
you can write:

DataRowView dview = (DataRowView) customersBindingSource.Current;
if(dview!=null)
    DataRow row = dview.Row;
else
   return null;
