Paged data in a WPF Grid control

问题 I have a Rest service that returns the data in pages. I know how many pages of data there is after getting the first result set. Now I want to consume this service in a WPF application, e.g. display the result in a Grid Control (or a list view). The problem is that the whole paging mechanism should be transparent to the end user, so they shouldn't trigger data fetching by any means other than scrolling in the grid. Is this possible and how would you tackle this problem? 回答1: Here is another

ASP.net Grid paging with merged rows

由 家住魔仙堡 提交于 2019-12-22 13:58:15
问题 I am currently using GridView to display tabular data. I need to merge cells in the first column that have equal values. At the moment I have code in the PreRender event to set the RowSpan property for me, and it's working fine. The problem is I cannot use paging, since the pages will split in the middle of a section where the first field is equal. I want the record count for paging to count one for each of the merged rows, rather than one for each sub-row. Is this possible with GridView or

问题 Ayende describes a really great way to get page count, and a specific page of data in a single query here: http://ayende.com/blog/2334/paged-data-count-with-nhibernate-the-really-easy-way His method looks like: IList list = session.CreateQuery("select b, rowcount() from Blog b") .SetFirstResult(5) .SetMaxResults(10) .List(); The only problem is this example is in HQL, and I need to do the same thing in an ICriteria query. To achieve the equivalent with ICriteria, I need to do something like:

问题 I am writing a wpf destop application, and would like to use SQL Server CE as a backend. I'm trying to come up with a good way to do efficient data paging. In SQL Server Express, I can do something like this: Select ID, FirstName, LastName From (SELECT ROW_NUMBER() OVER (ORDER BY ID) AS Row, ID, FirstName, LastName From TestTable ) WHERE Row > 1 AND Row <= 10 Is there anything comparable in SQL Server CE?

问题 I want to be able to take a sequence like: my_sequence = ['foo', 'bar', 'baz', 'spam', 'eggs', 'cheese', 'yogurt'] Use a function like: my_paginated_sequence = get_rows(my_sequence, 3) To get: [['foo', 'bar', 'baz'], ['spam', 'eggs', 'cheese'], ['yogurt']] This is what I came up with by just thinking through it: def get_rows(sequence, num): count = 1 rows = list() cols = list() for item in sequence: if count == num: cols.append(item) rows.append(cols) cols = list() count = 1 else: cols.append
