考虑下面的方法。 我得到的例外是问,而中继器结合。
Bindrepeater:
private void BindRepeater()
{
var idx = ListingPager.CurrentIndex;
int itemCount;
var keyword = Keywords.Text.Trim();
var location = Area.Text.Trim();
var list = _listing.GetBusinessListings(location, keyword, idx, out itemCount);
ListingPager.ItemCount = itemCount;
BusinessListingsRepeater.DataSource = list.ToList(); // exception here
BusinessListingsRepeater.DataBind();
}
GetBusinessListings:
public IEnumerable<Listing> GetBusinessListings(string location, string keyword, int index, out int itemcount)
{
var skip = GetItemsToSkip(index);
var result = CompiledQueries.GetActiveListings(Context);
if (!string.IsNullOrEmpty(location))
{
result= result.Where(c => c.Address.Contains(location));
}
if (!string.IsNullOrEmpty(keyword))
{
result = result.Where(c => c.RelatedKeywords.Contains(keyword) || c.Description.Contains(keyword));
}
var list = result;
itemcount = list.Count();
return result.Skip(skip).Take(10);
}
GetActiveListings:
/// <summary>
/// Returns user specific listing
/// </summary>
public static readonly Func<DataContext, IQueryable<Listing>> GetActiveListings =
CompiledQuery.Compile((DataContext db)
=> from l in db.GetTable<Listing>()
where l.IsActive
select l);
