basic: asp.net user controls: how to programmatically add attribute to all text box controls?

I have a "form field highlight" javascript that I've added to some of my
ASP.NET forms using the following syntax:

body.Attributes.Add("onClick", "highlight(event);");
body.Attributes.Add("onKeyUp", "highlight(event);");

Some of my forms have a great many text box controls that I want to
highlight.. I would much rather that ASP.NET do the work of looping through
all text boxes and applying these two attributes.

Can someone give me the dummies how-to? I'm using C#.

using System;

namespace WebControlLibrary1
{
/// <summary>
/// Summary description for NewTextBox.
/// </summary>
public class NewTextBox : System.Web.UI.WebControls.TextBox
{
public NewTextBox()
{
//
// TODO: Add constructor logic here
//

this.Attributes.Add("onClick","javascript:alert('Hello World')");

}
}
}

}
 
Hi KF,

As for your scenario, I think Mr Newbie's sugestion on use a custom derived
TextBox class to replace all the textbox(you'd like to highlight) is the
better apprach. Since the ASP.NET page's control structure may be very
complex, loop all the TextBoxes on a page will cause critical performance
problem, especiall when there any many container controls (such as DataGrid
/ DataList ) which also contains nested textboxes...

So do you think using a custom TextBox class ok? If you have any other
questions, please feel free to post here.
