[RESOLVED] Passing data between two DataTables

[charlie20]

Hia,

I'm looking to move data between two DataTables (with a twist) & am looking for some guidance......

I have a WinForms application that works as follows :-
- Form_A is the main form & has graphing elements on it
- Form_A has two DataTables (a RawDT & an AnalysisDT)
- Form_A calls Form_B
- Form_B is used to import data from flat files (.csv, etc.)
- Form_B has two DataTables (an OriginalDT & a FilteredDT)
- Form_B allows the user to select just a single column from the original flat file to import.

The idea behind the application is that the user can import a single column of numerical data, from a flat file. Analysis is then performed on the data, the results of which is then presented back to the user graphically.

I have the above working however I am struggling with passing the data from Form_B.FilteredDT to Form_A.RawDT. I've tried CopyToDataTable() without success as well as variations on :-
frm_Main ImportTo = new frm_Main();
ImportTo.RawDataGrid = FilteredDT;

Any suggestions / pointers would be most helpful.

Thanks all.
