Asp.net-r Epeater Control
The Repeater control is used to display a duplicate list of items that is necessarily controlled.

The data used to display the list on the webpage is found to be more flexible than repeater, such as gridview and detailview. Therefore, we will summarize some of the situations we encountered recently and keep them for future reference, don't ask du Niang now...
You may find something wrong.
1. The Repeater control can be an array, for example, an instance array of a class.

Paging is one of the common functions in development, especially the Repeater paging, which collects some information and finds that the Repeater paging is usually divided into two types.
1. False paging (PagedDataSource implementation) 2. Real paging. This article focuses on the latter. Although I use. net and oracle as examples

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:
Most of us are using repeaters to display data also we faced the situation of retrieving no result to display so the repeater will be empty or we will need to handle this case from code behind to check nu

Next I will analyze the three template controls mentioned above, which belong to Web server controls, repeater, datalist and DataGrid respectively.
1.What is a template control?
A: A template is a set of HTML elements and controls that form the layout of a specific part of the control, consisting of HTML and embedded server controls. When a control is running on an ASP. NET webpage, the control infrastructure disp
Nested use of the gridview, datalist, and repeater controls.
First, bind data to the external layer. This is easy to say.
The second step is to bind the Data Control in the inner layer. You should bind the data in the itemdatabind event of the outer control.
The procedure is as follows:
Protected void data_bind (Object sender, datalisteventargs e) // if the outer layer is datalist, the inner layer is Repeater
How do I find controls in Repeater's HeaderTemplate and FooterTemplate templates? In Repeater's ItemTemplate template, we can use the Items property to iterate through the rows and look for them with FindControl.As follows: Under the item command event for repeater: for (int i=0; i) { checkbox cb= (checkbox) Repeater1. Items[i]. FindControl ("CheckBox1"); if (CB. Checked) { // related data processing} }However, if the controls in th

Performance aspectsRepeater is better than DataList, if not very large amount of data, this difference is not reflected.Ease of UseRepeater and DataList background data binding is very simple, datasource= ... DataBind () It's OK.But the DataList in the layout of the operation more convenient, such as it provides selectitemtemplate,eidtitemtemplate, but repeater did not, so for a selected color or background picture changes, The best choice is DataList
Template note) The following code is the code for the page, and only the repeater part of the code is pasted, because you want to bind the data, such as () so before you can use it, import the name space first

How to get the data bound to the current item in the repeater event?

Because I switched from ASP to learning. net, a lot of ideas have to follow ASP, but in my just getting started, I found that the display data is generally bound to a dataset control (such as, repeater ), displaying Data in repeater is also easy. You only need to write But sometimes we need to dynamically attach the field content to a container (such as label) in the CS file, but in the background, en

Although repeater controls are not as commonly used as gridview controls, repeater needs to be used in some specific scenarios. In fact, in net2.0, formview controls can also achieve effects similar to repeater, in addition, all data is displayed through templates.
However, deleting a control in the Repeater control is

As mentioned in msdn, the data source object that can be used as a data binding control must inherit and implement the ienumerable or ilistsource interface.
The dictionary class obviously inherits and implements the ienumerable interface. So how do I bind a dictionary object to controls such as repeater?
