Using C# to populate a word mail merge document

See more:

C#

Hi,

I have a mail merge template which is similar to Bank Name in the header and a list of all branches in the details, in columnar format = branch name, address, manager, contact no. etc

I need to select the list of branches from a branch master table (ms access) for the selected bank and fill them to respective cols (col headings are already in the template).. Number of branches may vary from bank to bank.

In am using Microsoft.Office.Interop.Word and C# coding... Can I use TableStart and TableEnd model to achieve this? How?

=======
I am able to do the merge for all non=tabular data. My table is delimited by TableStart and TableEnd with variable no of row in the table... Code for table data merging should happen between TableStart and TableEnd when GridView == 1. I am not sure how to proceed for processing this
