[RESOLVED] Invalid cast exception

[Quasar6]

I'm getting an invalid cast exception which makes no sense whatsoever (see attachment).

It occurs no matter what the number in the cell is.

The ids variable is defined as so:

List<int> ids = new List<int>();

Just below the line creating the error is another line...

link_Main_RFITableAdapter.DeleteID((int)row.Cells[0].Value);

... which contains the same cast. This line does not produce the error whien I run the program without the first line.

Can anyone help? This is pretty urgent: I can't do much until I've fixed it.

Thanks in advance,
Qu.
