How to use repeater control in ASP.NET 2.0(C#)
The Repeater control is used to display a repeated list of items that are bound to the control. It enable the customization of the layout by each repeated list of items. The Repeater control may be bound to a database table, an XML file, or another list of items. The Repeater control has no built-in select and edit support.
Below are 2 simple Repeater controls. The first one display its items in a table, and the second one display its items separated by comma.
Define PositionData Class
If you're ever in the market for some great Windows web hosting, try Server Intellect. We have been very pleased with their services and most importantly, technical support.
public class PositionData
{
private string name; private string ticker; public PositionData(string name, string ticker) {
this.name = name;
this.ticker = ticker; } public string Name {
} public string Ticker {
} |
Invoking PositionData to add data, and use Repeater1, Repeater2 to bind data
display
void Page_Load(Object Sender, EventArgs e)
{
if (!IsPostBack) {
ArrayList values = new ArrayList();
values.Add(new PositionData("Microsoft", "Msft"));
values.Add(new PositionData("Intel", "Intc"));
values.Add(new PositionData("Dell", "Dell"));
Repeater1.DataSource = values;
Repeater1.DataBind();
Repeater2.DataSource = values;
Repeater2.DataBind(); } |
