getting the values of hiding columns on datagridview

[David]

can anybody help about this subject??? I have to hide some columns with
visible=false but I need their value. With a gridview in a website I used
datakeys, but with a datagridview there are no such thing.

You can still access the columns and manipulate their cell values even
when they're hidden. Just use the regular row and column syntax like
this:
// the second 0 is column index
dataGridView1.Rows[0].Cells[0].Value = "Hello";
or
// can also use column name
dataGridView1.Rows[0].Cells["Column2"].Value = "World";
