Question

I’ve got the following C# code in an MVC3 Controller Action.

public ActionResult MyDocuments(int Page)
{
    int start = (Page==1?1:(Page-1)*4);
    int end = (Page==1?4:start + 4);
    // start parameter begins at 1
    Archive docs = mps.GetArchive(start, end);
    ViewBag.docs = docs;
    if (docs.Rows.Count() < 4)
    {
        ViewBag.lastPage = 1;
    }
    else
    {
        ViewBag.lastPage = 0;
    }   
    ViewBag.pagenum = Page;
    return View();
}

The issue I have is that it always starts the next page with the last entry from the previous page.

What am I doing wrong here? I do not know how many pages I will have, I only need to check the number returned in the docs object to see if it is < 4, then I set the ViewBag.lastPage value to disable the next btn in my View and the ViewBag.pagenum sets the pagenum value in the View to the current page number.

Answer 1

I suspect that your mps.GetArchive(start, end) method is returning all records between start and end inclusive. Normally the end value should be excluded.

If you can’t change how the method works, call it as mps.GetArchive(start, end - 1).
