AlternatingitemtemplateDefines the content and layout of the alternate items. The so-called alternate item Mode means that the Repeater control and the datalist control allow parity items to display data in different content and layout forms, the odd number of rows is defined by the alternatingitemtemplate template (index number starts from 1), and the even number of rows are defined by the itemtemplate template (quotation marks start from 0 ). If onl
I posted a blog post about how to capture child controls in grieview. However, the gridview is too large, and it seems too cumbersome to pursue efficiency today. The requirement for capturing sub-controls in repeater exists. Therefore, after reading the relevant documents and trying several failed attempts, I learned some of the following experiences and gains to share with you.
First, let's take a look at the knowledge involved in implementing the

Using system. Data;
Using system. Web;
Using system. Web. UI. webcontrols;
2. Bind the Repeater control to the xmldatasource data source without Paging1) Foreground testrepeater. aspx file:

3. The Repeater control binds an XML file directly through dataview, with

Pagination is a Web applicationProgramOne of the most common functions, in ASP. net, although it comes with a paging DataGrid (Asp.net 1.1) and gridview (Asp.net 2.0) controls, its paging function is not satisfactory, for example, poor customization and paging functions cannot be implemented through URLs. Sometimes we need to paging datalist, repeater, and even custom data binding controls, and manually compile PagingCode
The development platform is 2003, and the control used is repeater.
Using system;Using system. Data;Using system. Data. sqlclient;
Namespace pagination. Class{/// /// Summary of pager./// Public class Pager{Public Pager (){//// Todo: add the constructor logic here//}/// /// /// /// /// /// /// Public dataset getcurrentdataset (string fieldlist, string condition, string pkey, string tablename, int sort, int pagesize, int cpage) // obtain the current
The Repeater control has five templates, which can be selected as needed:
1. itemtempplate: normal item
2. alternatingitemtemplate: staggered items
3. headertemplate: Header
4. footertemplate: footer
5. separatertemplate: Separator
Next, let's look at an example of pagination implemented by the Repeater control:
I. design interface:
Ii. Front-end code:
3. Create a database:

In many cases, we need the "select all" function when managing or viewing the list, which is very easy to implement in ASP. NET. Below I will demonstrate a little smallCodeThis function is implemented.A small function of JS is used to achieve full selection:Function checkall (E, itemname ){VaR AA = Document. getelementsbyname (itemname );If (AA = undefined) return;For (VAR I = 0; I }
First look at the implementation process in ASP: repeater.
Add a
Code for implementing batch deletion of Asp.net repeater:
Batch Delete involved content:1. patchwork of deleted SQL statements, such as delete from sosuo8 where ID in (, 5)2. After you click batch Delete, You need to verify the selected items on the client and prompt that the delete operation cannot be recovered. If it is implemented on the server, it will be very unfriendly, and slow speed is also a problem. The effect is as follows:
Detailed code
The pagination of datalist and repeater is required for the project. However, the control for loading data does not provide the paging function itself. You need to control the query statement for paging, but the statement is too complicated, or there are too many conditions, and the statement is difficult to write, but pageddatasource is much simpler, and the code distribution is clear and easy to understand.
The following example uses the pageddataso
