Asked On December 23, 2008 09:58 AM UTC

Good morning,

I wanted to create a template word doc, with tables.
In this table, in one of the cells, i wanted to have a list of values (for exemple strings).

So, to resume, i have a repeater, and in one cell in each row of the repeater, i have a repeater too.

But, i needn''t to use mailmerge.ExecuteNestedGroup, because this method needs database connection, and sql queries.

When i launch the process, i have an exception : reference not defined to an instance of object. at the line : 48.

And if you look at the generated document, (the last step in the directory : Steps of process), you can see the second child table start in the first row, like it keeps index of the first row.

Can you help me about this problem ?
Thanks in advance !

Thank you for your interest in Syncfusion products.

We have logged feature regarding to execute the nested mail merge without using DB connection and we have forward regarding this to our development team.

However, we can work around this issue by executing the child table alone in one document and parent table in one document. Finally merge these two documents table content to get the final output.

Please refer to the below custom sample for your template document:


Have a look into the sample and let us know if this helps you.

Best Regards,

Any word on when this feature will be added? Nested Mail Merge without a db connection.
If I have a DataSet with a DataRelation detailing a parent and child table, can I get this working currently? For example, merge Orders, and their Order details.
