Nested Mail Merge + vb.net 2010

[bikashdas]

Hi

Is there any way to do nested mail merge in vb.net . i can do only simple mail merge.
but not nested mail merge.

My Code gives:

<District1>

<District2>

<District3>

What i want

<District1>
           <Code ID><Code Name>
             1         pcs
             2         pcs

<District2>
           <Code ID><Code Name>
             14         psdscs
             23         sdsdsd


<District3>
           <Code ID><Code Name>
             15         ssxjs
             26         ksiss

The values of code id & code name will be found based district name.

Please help me.

Assume that i set my dataset/datatable as below

<District1><Code ID1><Code Name1>
<District1><Code ID2><Code Name2>

<District2><Code ID3><Code Name3>
<District2><Code ID4><Code Name4>

<District3><Code ID5><Code Name5>
<District3><Code ID5><Code Name5>
