how to Copy data of Datagridview?

Question

I got data from database into my datagridview via sqlDatasource1 i.e by using given tools, no programming et all.
I want to access rows of each Gridview row separately and then show them in textboxes of my own choice, instead of in gridview. How can I do that?
It works
numberOfRows = datagridview.Rows.Count;

but following doesn't

textbox1.Text=datagridview.Rows[0].cells[1].Text;
Dont know why it doesn;t?

Then I tried to get data of this gridview to another but it didn;t work too.

Help me plzzz.....I m struck here
