I have a listview that displays products. I have a datapager associated with the listview. I control the visibilty/population of product details by a query string value "prodID". I need to make sure that the right page is active when the page is loaded. So if prodID 10 exists on page 2 in the listview, then page 2 will be the active page when navigating to the URL (with prodID in the query string). prodID is a datakey in the listview.

Just use the SetPageProperties method for the datepager control in your code behind, as such:

int startRowIndex = 0;
int prodID = 0;

//Get pageIndex from Query String
prodID = int.Parse(Request.QueryString["prodID"].ToString());

//Get the row to start the page
startRowIndex = prodID

DataPager1.SetPageProperties(startRowIndex, DataPager1.PageSize, true);

You could put this code in the Page_Load method, probably the most common.  Only on the initial load I believe, so you may find that you want to put it inside an If Then that checks whether you are hitting the Page_Load method on a postback or if it is the initial load.

You just need access to the DataPager control, so any method in the life cycle after the Load ViewState method.  Look up the asp.net page life cycle and it will become more clear of what is happening and how the page request is processed.
