Add item from one datagrid to another

Actually such functions are not thread safe neither they should be performed. But anyways, if you still have to do that. i would recommend that you create a member in your form (the one that has to receive the value). Then pass that item to that member and load it in the form. You may also want to use events. 

 

As I said, it is a totally stupid idea. Perhaps you would need a service as a third-party which would handle them.
