this is the code that I use (below)

basically If I select the row, it work fine, but if I click on a single cell it return an exception

 Private Sub dgvShowBooks_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvShowBooks.CellClick




        txtBookName.Text = dgvShowBooks.Rows(e.RowIndex).Cells(0).Value

            txtAuthors.Text = dgvShowBooks.SelectedRows(0).Cells("Authors").Value
            txtPublishers.Text = dgvShowBooks.SelectedRows(0).Cells("Publisher").Value
            DatePublished.Text = dgvShowBooks.SelectedRows(0).Cells("Date").Value
            ckbHold.Checked = dgvShowBooks.SelectedRows(0).Cells("IsOnHold").Value

            'store values
            BookISBn = dgvShowBooks.Rows(0).Cells("BookISBN").Value
            currentBookTimestamp = dgvShowBooks.Rows(0).Cells("BookTimeStamp").Value



     


      If dgvShowBooks.SelectedRows(0).Cells("Image").Value Is DBNull.Value Then


         ' *****************  NEED TO PROVIDE A DEFAULT IMAGE FOR EMPTY IMAGES

      Else
         'read image converitng a byte array to an image
         PictureBox.Image = workWithImage.ByteToImage(dgvShowBooks.SelectedRows(0).Cells("Image").Value)

      End If
     

   End Sub

Hi AngelIII,

I followed your suggestion, but I get
Index was out of range. Must be a non negative and less than the size of the collection.

the strange thing is that  the debugger does not go into the sub..
it throws the exception as soon as I click. If I then click on continue, the debugger reload the datagrid again and then no exception is trhown
