Custom Template, meet the requirements of rolling trigger page button is available, or does not display the scroll bar, add a trigger, rolling into pages, the code can be a bit complicated,

Simple, allowing the emergence of the scroll bar, page button has been, fixed number of nodes in the current page shows, that's good to get it

Consider the building Lord, what is the TreeView? TreeView node X need paging to display a subset? You ever thought about whether your data source intermediate should be a filter, or is simply the logical function of discretion, something should be separated to the other controls or components,

"Front page shows 10 nodes, point the next page will show another 10 nodes" this is the business logic, if too lazy to take the manager according to the business logic data structure, so is often costly randomly change the interface people dead,

CodePudding user response:

You in defining business logic data structure Model when they write data grouped by page, and then ask your product manager and out of this idea to input data, according to the structure you see they are willing to don't want to? If you like, then you take a few minutes to write a data import code to go,

Is, in fact, I don't really to "business logic" problem, this problem can see some people all of a sudden a Tree hung a waste subproject (200 muck project, for example, who see?) Without the information well, it is very simple, this is the product model and data classification in the field of the problem of low,
