This article mainly introduces how to deal with line commands and paging in ASP.NET. It is very detailed and has a certain reference value. Friends who are interested must finish reading it.

1. Line command processing

(1) background code: operation line

/ / if it comes from the function operation in the html response

If (e.CommandNameplate = "addAge") {

/ / get the line number

Int index= ((ListViewDataItem) e.Item) DispalyIndex

/ / get the primary key value of the current operation line

/ / DataKeys stores all the ID and fetches the index ID

Guid id= (Guid) ListView1.DataKeys [index] .value

Table Adapter adapter=new Table Adapter ()

Adpter. Custom database function addAge

/ / data binding

ListView.DataBing ()

}

(2) sort

CommandName= "Sort"

CommandArgument= "ID"

Internal sorting, low efficiency

2. DataPager paging

PageControlID: which ListView is paged

Advanced pagination:

Query subquery

Select* from

(Select id,name,age,row_number () over (order by id) rownum from T_Users) t

Where t.rownum > 11and t.rownum@startRowIndex and t.rowRow
