Control.DataBinding Event


Occurs when the server control binds to a data source.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public event EventHandler DataBinding

This event notifies the server control to perform any data-binding logic that has been written for it.

/* Create a class that implements the ITemplate interface.
   This class overrides the InstantiateIn method to always
   place templates in a Literal object. It also creates a 
   custom BindData method that is used as the event handler
   associated with the Literal object's DataBinding event.  

using System;
using System.Web;
using System.Data;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace UsingItemTemplates
    public class GenericItem : ITemplate
        private string column;

        public GenericItem(string column)
            this.column = column;

        // Override the ITemplate.InstantiateIn method to ensure 
        // that the templates are created in a Literal control and
        // that the Literal object's DataBinding event is associated
        // with the BindData method.
        public void InstantiateIn(Control container)
            Literal l = new Literal();
            l.DataBinding += new EventHandler(this.BindData);
        // Create a public method that will handle the
        // DataBinding event called in the InstantiateIn method.
        public void BindData(object sender, EventArgs e)
            Literal l = (Literal) sender;
            DataGridItem container = (DataGridItem) l.NamingContainer;
            l.Text = ((DataRowView) container.DataItem)[column].ToString();
