问题 I have a GridView which needs to page and sort data which comes from a collection of Customer objects. Unfortunately my customer information is stored separately...the customer information is stored as a Customer ID in my database, and the Customer Name in a separate DLL. I retrieve the ID from the database using Entity Framework, and the name from the external DLL through a partial class. I am getting the ID from my database as follows: public class DAL { public IEnumberable<Customer>

问题 I want to use the scrollview as something like a picker in horizontal mode. The scrollview holds up to seven subviews. Each subview represents a value. Always three views are visible and the one in the middle is the selected one. Scrollview visible at start: __ | V1 | V2 Scrollview set to view/value two: V1 | V2 | V3 Scrollview set to last value: V2 | V3 | __ The real problem I have got is the "pagingEnabled" flag. If pagingEnabled is set to YES the scrollview pages always three subviews

问题 I would like to use a GroupTemplate to separate a list of items into groups. However, I need each Group to be numbered sequentially so I can link to them and implement some JS paging. I'm binding to an IEnumerable Here's some pseudo code. I would like the output to look like this: <a href="#group1">Go to Group 1<a> <a href="#group2">Go to Group 2<a> <a href="#group3">Go to Group 3<a> <ul id="group1"> <li>Item</li> <li>Item</li> <li>Item</li> </ul> <ul id="group2"> <li>Item</li> <li>Item</li>

问题 I Googled for a long time but I still don't understand how it works as most of the explanation are very technical and there are no illustrations to make it clearer. My primary confusion is that what is its'difference with virtual memory? I hope this question will have a very good explanation here so that other people who ask the same question can find it here when they Google it. 回答1: I have to admit, those two concepts can seem quite complicated and similar at the beginning. Sometimes they

问题 I wanna do something like that public IQueryable GetPaged<TSource>(IQueryable<TSource> query, int startIndex, int pageSize) { return GetSession() .Linq<TSource>() .UseQuery(query) .Take(pageSize) .Skip(startIndex); } So you can put any IQuerable statement and "it becomes paged" or it will be paged. I am using LINQ to NHibernate. I hope you get it, sry for this bad english :o edit: Maybe my approach is the wrong one, is it? 回答1: This is copied from working code: public static class

问题 Been googling all this while on how to convert an html table to something pagable and sortable, and I have stumbled across jqGrid jquery plugin. I've learned so far that we have to call tableToGrid() to convert the table (which we pass as a jquery selector string to the method). I've also tried a host of other things, like for e.g: tableToGrid('#GridView1'); $('#GridView1').jqGrid({ rowNum: 10, pager: '#pager', rowList: [10,20,30] }); But all these do not provide me with the proper result. Is

问题 I've got a System.Generic.Collections.List(Of MyCustomClass) type object. Given integer varaibles pagesize and pagenumber, how can I query only any single page of MyCustomClass objects? 回答1: If you have your linq-query that contains all the rows you want to display, this code can be used: var pageNum = 3; var pageSize = 20; query = query.Skip((pageNum - 1) * pageSize).Take(pageSize); You can also make an extension method on the object to be able to write query.Page(2,50) to get the first 50
