ASP.NET Web Forms - Repeater Control
The Repeater control is used to display a repeated list of items that are bound to the control.
Binding a DataSet to the Repeater Control
The Repeater control is used to display a repeated list of items that are bound to the control. The Repeater control can be bound to a database table, an XML file, or any other list of items. Here, we will demonstrate how to bind an XML file to a Repeater control.
In our example, we will use the following XML file ("cdcatalog.xml"):
First, import the "System.Data" namespace. We need this namespace to work with DataSet objects. Include the following directive at the top of your .aspx page:
Next, create a DataSet for the XML file and load the XML file into the DataSet when the page is first loaded:
sub Page_Load if Not Page.IsPostBack then dim mycdcatalog=New DataSet mycdcatalog.ReadXml(MapPath("cdcatalog.xml")) end if end sub
Then, create a Repeater control in your .aspx page. The content inside the element is rendered first and appears only once in the output, while the content inside the element is repeated for each "record" in the DataSet. Finally, the content inside the element appears only once at the end of the output:
... ... ...
Then we add the script to create the DataSet and bind the mycdcatalog DataSet to the Repeater control. We then use HTML tags to populate the Repeater control and bind data items to cells within the section using :
Example
sub Page_Load if Not Page.IsPostBack then dim mycdcatalog=New DataSet mycdcatalog.ReadXml(MapPath("cdcatalog.xml")) cdcatalog.DataSource=mycdcatalog cdcatalog.DataBind() end if end sub
| Title | Artist | Country | Company | Price | Year |
|---|---|---|---|---|---|

Using
You can add an element after the element to define the appearance of alternating rows in the output. In the following example, every other table row will have a light gray background:
Example
sub Page_Load if Not Page.IsPostBack then dim mycdcatalog=New DataSet mycdcatalog.ReadXml(MapPath("cdcatalog.xml")) cdcatalog.DataSource=mycdcatalog cdcatalog.DataBind() end if end sub
| Title | Artist | Country | Company | Price | Year |
|---|---|---|---|---|---|

Using
The element is used to define a separator between each record. In the following example, a horizontal line is inserted between each table row:
Example
sub Page_Load if Not Page.IsPostBack then dim mycdcatalog=New DataSet mycdcatalog.ReadXml(MapPath("cdcatalog.xml")) cdcatalog.DataSource=mycdcatalog cdcatalog.DataBind() end if end sub
| Title | Artist | Countr |
