Control about the 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 list of data, which is defined below (see also SDK):

Describes how to use the Repeater control in ASP. NET data binding, asp. netrepeater
I. Repeater for binding controls. NET encapsulates a variety of data binding controls, such as GridView and DataList, but this article will start with Repeater, because Repeater only provides basic data binding templates, no built-in
The Repeater control provides maximum flexibility among the three ASP. NET data Web controls: the HTML tags it presents can be specified. The DataGrid or DataList automatically contains the content specified by the developer in the preset HTML Tag. Different from them, the Repeater strictly generates the specified HTML Tag during rendering. Therefore, if you do not want to use HTML

In the past, the repeater was more efficient than the DataGrid, but I don't know if I didn't test it. I was shocked by a test!
I used the stress testing software (ACT) that comes with vs to test the performance of the two, and measured by the number of accessible users per second.
However, the result is beyond my expectation that the DataGrid is more efficient than the repeater!
Let's take a closer look
In this demo, we implement the functionality of this Repeater control data export Excel.we prepare an object :
Copy Code code as follows:

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.
Compared to GridViews and DataList, Repeater is a lightweight, flexible control that consumes a lot less energy than they do. The drawback is that the function is slightly thin, especially for the binding data source without data, often to us
The Repeater control provides the greatest flexibility in the three ASP tutorials. NET Data Web controls: The HTML markup It renders can be specified. The DataGrid or DataList automatically contains the developer-specified content in the preset HTML markup. Unlike them, Repeater will strictly generate the specified HTML markup when rendered. Therefore, if you do not want to use HTML

In the previous articles about AJAX, AJAX technology can be used to develop highly-efficient website applications, however, it is far from enough to have AJAX technology for B/S project development. More things will be learned from B/S, however, compared with the complex logic structure of C/S, B/S is still very simple during development.
Data Binding controls are often used when developing B/S projects ,. NET platform has well encapsulated these controls, as long as a slightly expe
Introduction
In the previous 7 chapters on DataList and Repeater, we created examples of read-only and editable deletes. In order for DataList to have Edit and delete functions, we have added some button in the ItemTemplate, when clicked, causes postback, and fires the related event according to the button's CommandName property. For example, adding a button commandname to "Edit" fires the EditCommand event when postback, and fires DeleteCommand if C
Step Seventh: Add sorting functionality to the custom pagination repeater
Now that you have finished customizing the paging, let's add the sorting function. The getproductspagedandsorted method of the PRODUCTSBLL class has the same startrowindex and maximumrows parameters as getproductspaged. The difference is that it also has one more sortexpression parameter. Using the Getproductspagedandsorted method in sortingwithcustompaging.aspx we need to:

Pagination | control | Problems before the time to do ASP is not short, but do asp.net I am a novice. A few days ago to do the project, encountered a problem, requiring more complex data format display, with a DataGrid is very difficult to achieve, and later used the Repeater control to achieve. But this brings up a new problem: How to page pagination? Repeater does not have a built-in paging capability. La

Introduction
Most of the Times while creating database driven Web pages like product listing, employee directory, etc. we display the D ATA in grid format. ASP.net has come up with Web Controls like DataGrid, DataList and Repeater this allow to display your data in tabular Format easily.

We may all be familiar with the DataGrid, but if we have a large amount of data, we have to consider using repeater as our data-bound control. The main difference between a repeater control and a DataGrid (and DataList) control is how HTML is handled. Asp. NET creates HTML code to display the DataGrid control, but repeater allows developers to decide how to displ

I used to think that Repeater is more efficient than DataGrid, but I don't know if I don't test it. A test is a fright!

Let's take a closer look at my test
The repeater control implements its paging functionality in conjunction with PagedDataSource, which can be used if control developers need to provide paging support to custom data-bound controls This article explains Repeater control and PagedDataSource to realize its paging function. The PagedDataSource class encapsulates properties that allow data source controls (such as the DataGrid, GridView) to per
There is no FindControl method in the Repeater FooterTemplate, and the FooterTemplate can not be converted to RepeaterItem, although in repeater events, The RepeaterItemEventArgs parameter can be used if (E.item.itemtype = = Listitemtype.footer) To identify this Footer, but not at other times.
