Init event for control doesn't fire

S

Shimon Sim

I have Panel control on the page. I am handling Init event for it. It
doesn't seem to fire at all. Why?
Thank you
Shimon.

Like this. All of them fire except for Init
#region Web Form Designer generated code

override protected void OnInit(EventArgs e)

{

//

// CODEGEN: This call is required by the ASP.NET Web Form Designer.

//

this.Betterpanel2.Load += new System.EventHandler(this.Betterpanel2_Load);

this.Betterpanel2.Unload += new
System.EventHandler(this.Betterpanel2_Unload);

this.Betterpanel2.PreRender += new
System.EventHandler(this.Betterpanel2_PreRender);

this.Betterpanel2.Init += new System.EventHandler(this.Betterpanel2_Init);

this.Betterpanel2.Disposed += new
System.EventHandler(this.Betterpanel2_Disposed);

InitializeComponent();

base.OnInit(e);

}


/// <summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// </summary>

private void InitializeComponent()

{


this.Disposed += new
System.EventHandler(this.CompositeControlTest_Disposed);

this.Unload += new System.EventHandler(this.CompositeControlTest_Unload);

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

this.Init += new System.EventHandler(this.CompositeControlTest_Init);

this.PreRender += new
System.EventHandler(this.CompositeControlTest_PreRender);

}

#endregion

Well, that explains it :)

Child controls' OnInit is called before the Page's OnInit. You're registering
for the events too late. You can put <asp:panel OnInit="MyEventHandler" ...
/> into the ASP directly and that will register your event handler when the
contol is created.

Thanks for Brock's Great explanation and suggestions.

Hi Shimon,

Like Brock has mentioned, the OnInit event of the Page is too late for
registering event handler for sub control(added statically)'s Init event).
Because all the static sub control's Init event is fired when they are
being added into the parent container which is before the Page's OnInit
function. You can try using Brock's suggetion on registering the event
handler in aspx page inline.

Thanks & Regards,
