I have a problem with binding Listview to my database using entity framwork.
This code only shows the first row of the table but the records do not show:

C#

var item = (from p in db.tbl_film
            select p).FirstOrDefault();
string[] items = {item.flm_id.ToString(),item.flm_name,item.flm_description,item.flm_category };
foreach (var itemlist in items)
{
    ListViewItem lvi = new ListViewItem(items);
    listView1.Items.Add(lvi);
}

Solution 1

Your query returns the first record always because you have used

FirstOrDefault();

in your linq query

Solution 3

instead of FirstOrDefault() use ToList() in your query.You will get all the records from database.FirstOrDefault() instructs Entity framework to return first record of table only.

C#

var items = (from p in db.tbl_film
            select p).ToList();
foreach (var itemlist in items)
{
    ListViewItem lvi = new ListViewItem();
    lvi.Id=itemlist.Id;
    lvi.Name= itemlist.Name;
    //And so on...
    listView1.Items.Add(lvi);
}

ID and Name
Where do they come from?

I just assume that your ListViewItem class has Id and Name property,to which i have assigned dynamically fetched data from Linq query.I also assume that my record from table will have Id and Name property as its members.

C#

var items = (from p in db.tbl_film
                         select new {
                             ID=p.flm_id,name=p.flm_name,description=p.flm_description,link=p.flm_link,sub=p.flm_sub_link,cate=p.flm_category,pic=p.flm_pic
                         });
            foreach (var itemlist in items)
            {
                ListViewItem lvi = new ListViewItem(itemlist.ID.ToString());
                lvi.SubItems.Add(itemlist.name);
                lvi.SubItems.Add(itemlist.description);
                lvi.SubItems.Add(itemlist.link);
                lvi.SubItems.Add(itemlist.sub);
                lvi.SubItems.Add(itemlist.cate);
                lvi.SubItems.Add(itemlist.pic);
                listView1.Items.Add(lvi);
            }
