Totally unclear to me what is going wrong. What is exportpdf. Is that the code that you are posting ? That would mean that the code is simply not called. So you did not post the code containing the error.

Modify as fallows

C#

if (dataGridView1.Rows[i].Cells["OctroiCode"].Value == null)//(dataGridView1.Rows[i].Cells["OctroiCode"].Value != null)
                       {
                           MessageBox.Show("Please select octroi Code");
                           dataGridView1.Rows[i].Cells["OctroiCode"].Selected = true;
                           return;
                       }

The main problem is return line where your function execution get ended.

In for loop you are validating that OctroiCode should have a value otherwise you are prompting a message and returns from the function, correct me if I am wrong.
So it seems that your ExportPDF function must have some problem so you should provide the code of that.

If datagridviewcombobox column is null so,that should be generate error (MessageBox.Show("Please select octroi Code");
If not null than execute the function ExportPdf();, but problem is- If comboboxcolumn not null sot that was generating an error msg (It's a wrong).
