Submitting a form problem

(ASP.NET)

I have a webpage created in Dreamweaver MX which contains a datagrid showing orders. Within the grid is a hyperlink field which redirects users to a new page where they can see details. For some reason MX insists that the datagrid must be within a form.

This works fine.

I now wish to add a drop down showing a list of customers. I want the users to be able to choose from the list, click on a button which takes them to a new page showing custmer details. Normally I would put this in a form which would submit and redirect the user to the new page using either Post or Get.

This unfortunatly doesnt work because I can only have 1 form on a page. If I make the whole page a form containing both the grid and combo then I end up with an error :

"The View State is invalid for this page and might be corrupted."

I think this may be because I end up submitting the Combo and the grid.

Can anyone think of a solution or help in some way?

I'm pretty new to .net so please be gentle. I am fragile at the moment.
