How to reset paging in a dataformwebpart?

Question

In SPD 2010 I created a datasource which produces XML, based on the requests you send to it. The datasource works correctly, because when I put it on a page, it shows me the results I expect. Because the datasource can return a large number of results, I turned on paging in the dataformwebpart I use to present my datasource. This also, works as expected.

Troubles started when I made it possible to dynamically update the request to the datasource through a webpart connection from a SimpleHtml webpart.

The use case that goes wrong, is as follows: - User opens page and sees a list of items (returned by the datasource). - User goes to page 2 and decides that this is not what he wants to see. - User therefore enters a search term and presses 'Search'. - On the background: when user presses 'Search' the new search term is send through a webpart connection to the datasource, which dynamically reloads the data (without completely reloading the page), so user sees new results. - However, user was on page 2 when he initiated the search and he still is on page 2 of the search results after the datasource got updated on the page.

The problem: how do I reset the paging in a dataformwebpart when the user enters a new search term?

Answer 1

I'd probably work it so that you force a page refresh with the search term as a query string parameter that the data view web part can pick up and filter by.
