ASP.NET Tutorial. How to use Repeater

In this article, I'll show you how to use Repeater in ASP.NET page.

Here is an example of Repeater:

I store the user in table "Client_NetroStar" in SQL Server.  There are five fields in the table:

• ID
• Login
• FirstName
• LastName
• DateAdded

1. First Step - Insert the Repeater Control on page.

Repeater control allows you to create templates. For example you can use a template to customize the layout of the individual rows.

• HeaderTemplate - template for elements that you want to render once before your ItemTemplate section.
• ItemTemplate - template for elements that are rendered once per row of data.
• AlternatingItemTemplate - template for elements that are rendered every other row of data. This allows you to alternate background colors, for example.
• SeparatorTemplate - template for elements to render between each row, such as line breaks.
• FooterTemplate - template for elements that you want to render once after your ItemTemplate section.

Here is the part of the “ClientNetroStar.aspx” page that contains Repeater:

The Repeater has an attribute ID= "rptList". It is used in  Code Behind (ClientNetroStar.aspx.cs) . Repeater uses the HeaderTemplate to insert <table> .  Then it uses the ItemTemplate to display a LinkButton control that has our data in it. I'll come back to this in the next  step.

The FooterTemplate is not necessary, but I put it in </table>.

2. Second Step - Get the Data to Repeater.

Here is the Page_Load event in the Code Behind file.

The first five lines open a database connection and retrieve the contents of the Client_NetroStar table. The last two lines bind our Repeater control to the DataReader.
