AutoEventWireup

AutoEventWireup is an attribute of the @ Page directive. The AutoEventWireupattribute may have a value of true or false.


You can specify a default value of the AutoEventWireup attribute in several places:

• The Machine.config file
• The Web.config file
• Individual ASP.NET Web Forms (.aspx files)
• Web User Controls (.ascx files)

When AutoEventWireup is true, ASP.NET does not require that you explicitly bind event handlers to a page event such as Load.

When AutoEventWireup is false, you must explicitly bind the event to a method.

For example, if you have a Page_Load method in the code for a page, the method will be called in response to the Load event only if you write code like this.

public partial class AutoEventWireupExample : System.Web.UI.Page

{

    protected void Page_Load(object sender, System.EventArgs e)

    {

        Response.Write("Executing Page_Load");

    }

    override protected void OnInit(EventArgs e)

    {

        this.Load += new System.EventHandler(this.Page_Load);

    }

}
