Control.DataBinding Event
.NET Framework (current version)
Occurs when the server control binds to a data source.
Assembly: System.Web (in System.Web.dll)
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); container.Controls.Add(l); } // 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(); } } }
