linq2sqlコレクションをGridViewにバインドする最良の方法は何ですか?私は組み込みのページネーションとソートを使用したいのですが?Linq2sql/GridView:ページネーションが機能していませんか?
public static void BindEnquiryList(EnquiryQuery query, GridView view)
{
DataContext db = DataContextManager.Context
//view.DataSource = (from e in EnquiryMethods.BuildQuery(query)
view.DataSource = (from e in db.Enquiries
select new
{
Id = e.Id,
Name = e.Name,
PublicId = EnquiryMethods.GetPublicId(e.PublicId),
What = e.WorkType.DescriptionText,
Where = e.EnquiryArea.DescriptionText,
Who = e.EnquiryType0.DescriptionText,
When = e.EnquiryTime0.DescriptionText,
PriceRange = e.EnquiryPrice0.DescriptionText,
DisplayPriceRange = e.EnquiryPrice0.Display,
Description = e.Description,
Published = e.EnquiryPublished
});
view.DataBind();
}
をそして、GridViewコントロールは、20をPAGESIZEするように設定されている(かつ適切に20を示している)が、実行には、ロードするために永遠にかかり、私は、SQLのログイン時に私が手::
私が試した
SELECT [t0].[Id], [t0].[Name], [t0].[PublicId] AS [publicId], [t1].[DescriptionText] AS [What], [t2].[DescriptionText] AS [Where], [t3].[DescriptionText] AS [Who], [t4].[DescriptionText] AS [When], [t5].[DescriptionText] AS [PriceRange], [t5].[Display] AS [DisplayPriceRange], [t0].[Description], [t0].[EnquiryPublished] AS [Published]
FROM [dbo].[Enquirys] AS [t0]
LEFT OUTER JOIN [dbo].[WorkTypes] AS [t1] ON [t1].[Id] = [t0].[EnquiryPlace]
LEFT OUTER JOIN [dbo].[EnquiryAreas] AS [t2] ON [t2].[Id] = [t0].[EnquiryPlace]
LEFT OUTER JOIN [dbo].[EnquiryTypes] AS [t3] ON [t3].[Id] = [t0].[EnquiryType]
LEFT OUTER JOIN [dbo].[EnquiryTimes] AS [t4] ON [t4].[Id] = [t0].[EnquiryTime]
LEFT OUTER JOIN [dbo].[EnquiryPrices] AS [t5] ON [t5].[Id] = [t0].[EnquiryPrice]

トップがありません。私は、GridViewがTakeとSkipの操作を管理することを期待していましたか?
