I have a master/detail data structure (a request which has several items in it) so I have created 2 lists to handle this.

I am seeking a way to let my users input data into these lists.

In this post clayton cobb has suggested to have a page with 2 infopath form webparts in it.

How can I have ONE submit button which submits both of these forms simultaneously?

Any helps are appreciated

Thank you

Hi,

We can create a visual web part and customize a form to achieve your requirement.
