TextBox Focus Question

[Joe Delphi]

Hi,

I have more experience working with Windows.Forms than with WebForms
and sometimes it trips me up.

When my page loads, I want a particular textbox to have the focus. I
am attempting to do it using logic like this:

if TextBox1 CanFocus then
TextBox1 Focus()
end if

But the compiler does not like that because the web version of the
TextBox class does not have CanFocus or Focus()

How do I set the focus to the desired textbox?

Since focus is a client side action you'll have to do it with some
JavaScript. In version 1.1 of the framework, you can follow the
instructions on http://www.davefancher.com/BlogEntry.aspx?ArticleID=14 [C#
example but the conversion should be easy]. Version 2 has this
functionality built in.

Joe you can use this in page_load
and make sure you import "Imports System.Text
and txtAge is the ID of your textbox

Dim strBuilder As StringBuilder = New StringBuilder
strBuilder.Appe nd("<script language='javas cript'>")
strBuilder.Appe nd("document.ge tElementById('t xtAge').focus() ")
strBuilder.Appe nd("</script>")
RegisterStartup Script("Focus", strBuilder.ToSt ring)

Hope it helps

Hi Joe,

First of all you should understand that web application is different from
desktop application. The web application runs on a client-server mode. Any
web server control only exists on server-side. Once rendering to client-side,
it is destroyed. And corresponding html component is shown on client-side.
Actually a 'focus' event occurs on client-side. So client-side JavaScript
code can be used to conduct focus and other events.

Following code snippet shows how to set TextBox focus:

String strFocus = "<script>docume nt.all." + txtbox.ID + ".focus();</script>";
Page.RegisterSt artupScript("fo cusTextBox", strFocus);
