Repeater.OnItemDataBound Method

Raises the ItemDataBound event.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

protected virtual void OnItemDataBound (
	RepeaterItemEventArgs e
)
protected void OnItemDataBound (
	RepeaterItemEventArgs e
)
protected function OnItemDataBound (
	e : RepeaterItemEventArgs
)

Parameters

e

The RepeaterItemEventArgs object that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Consuming Events.

Notes to Inheritors When overriding OnItemDataBound in a derived class, be sure to call the base class's OnItemDataBound method.

The following example illustrates a way to handle the ItemDataBound event of the Repeater control. The data is modified after it is bound to an item in the Repeater control but before it is rendered on the page.

<%@ Page Language="C#" AutoEventWireup="True" %>
<html>
 <head>
    <script language="C#" runat="server">
       void Page_Load(Object Sender, EventArgs e) {
 
          if (!IsPostBack) {
             ArrayList values = new ArrayList();
 
             values.Add(new Evaluation("Razor Wiper Blades", "Good"));
             values.Add(new Evaluation("Shoe-So-Soft Softening Polish", "Poor"));
             values.Add(new Evaluation("DynaSmile Dental Fixative", "Fair"));
 
             Repeater1.DataSource = values;
             Repeater1.DataBind();
          }
       }
 
       void R1_ItemDataBound(Object Sender, RepeaterItemEventArgs e) {
                              
          // This event is raised for the header, the footer, separators, and items.

          // Execute the following logic for Items and Alternating Items.
          if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) {
                 
             if (((Evaluation)e.Item.DataItem).Rating == "Good") {
                ((Label)e.Item.FindControl("RatingLabel")).Text= "<b>***Good***</b>";
             }
          }
       }    
 
       public class Evaluation {
         
          private string productid;
          private string rating;
 
          public Evaluation(string productid, string rating) {
             this.productid = productid;
             this.rating = rating;
          }
 
          public string ProductID {
             get {
                return productid;
             }
          }
 
          public string Rating {
             get {
                return rating;
             }
          }
       }
