Repeater
The Repeater (foreach) is used to traverse and display the data in the bound data source in the format. The format of each data entry is determined by the Repeater's

Use of repeater controls
The Repeater control is a data display control that allows you to customize the layout by repeatedly using the specified template for each item displayed in the list.
To display data, you must first create a template to bind the data list. The module definition is as follows (see SDK ):
1. template descriptionHeadertemplateThe element that is rendered once before all data bound ro
functional requirements, the general control has the following functions: dynamic binding, a project consists of a check box and a text box.
Finally, we decided to use repeater for expansion. Repeater binding should be efficient and clean. Then there is the option problem.
Define a new repeater template. The above effect is displayed when
The Repeater does not have its own paging function, so it uses the AspNetPager distribution component. The Code is as follows:SWhere =. Format (, sId );
MDataTable = DAL. Log. GetList (sWhere). Tables [];
AspNetPager1.RecordCount = mDataTable. Rows. Count;
PPS = PagedDataSource
{
DataSource = mDataTable. DefaultView,
CurrentPageIndex = AspNetPager1.CurrentPageIndex -,
PageSize = AspNetPager1.PageSize,
AllowPaging =
};
Repeater1.DataSource = PPS;

In the morning, we shared "Repeater control dynamic change columns (Header, Item, and Foot) information", which is used to dynamically change some columns.
Although it is not completely dynamic, it has achieved the initial effect. If you are careful, you can easily get it out. Now I have another article. Insus. NET does not re-write but wants to refactor the cs code, because the code in the previous article is simple but redundant.Reconstruction start

The repeater and datalist controls are paginated. One method is to use the pageddatasource class, which is relatively simple. The method is as follows:
Public void listbind (){Myconn = new oledbconnection ("provider = Microsoft. Jet. oledb.4.0; Data Source =" + server. mappath ("/data. mdb "));Oledbdataadapter mycomm = new oledbdataadapter ("select * From guestbook order by gbdate DESC", myconn );Dataset DS = new dataset ();Mycomm.

A few days ago, I became a corporate website. Binding data with the repeater control at the front end is a typical example, so it is recorded.
I dare not say what it provides for prawns? It only serves as a reference for a bird just like me in this situation.
The title is displayed on the frontend. Click to view details.
First, add a page to bind data.
Add another page to display the Detailed information of the data: Detailed. aspx

Use the pageddatasource class to implement pagination of repeater and datalist. Pageddatasource encapsulates the pagination attribute of the DataGrid. We can perform pagination like the DataGrid.

When making repeater a user control, the columns obtained by using attributes to receive various data sources (in the datatable format) are also different. Therefore, the front-end scripts should be prepared as follows:
When I use eval to bind a value, arr [k] will report an error saying that K cannot be found here. I have tried several methods but I don't know how to dynamically bind it, the prawns know what to do! The getcolname (); method is the ba

Repeater does not use emptytemplate by default. Try to use the custom control to rewrite databind. I think it is too complicated. I accidentally found an almost invincible method from a foreigner's blog:
