aspx thread: <input> box focus
Message #1 by "J Donahue" <jdonahue@f...> on Thu, 25 Jul 2002 20:24:28

I know Javascript uses focus to target an <input> box. Is there a way to
target a certain <input> box from within a NET server control??
I have a form and have disabled the enterkey, replacing it with the tab
key. The zip code field checks the user entry and if found, fills in the
city, state. The problem is, once it does that the cursor is no longer
on the form. I simply want to target the next <input> box
thanks!!

Once you have done your city and state fill routine can't you setfocus on
the control you want?

I'm using VB.NET and apparently it doesn't support setfocus. I simply
tried <myvar>.setfocus and it errors. I looked it up and it said
setfocus was replaced by activate but <myvar>.activate isn't valid either.

Per one of my VB.NET books setfocus has been replaced with focus. Does
focus pop up with intellisense?

I truly am befuddled as I've seen a few references to the new focus method
which I also can not bring up in Intellisense. MSDN lists vb6 to vb.net
changes and it also says Setfocus is now focus.

I realize now that I have been seeing the focus method for Winforms not for
Webforms. More research...

I imported Systems.Web.UI.Page, then I have the following:
HTML code:
<asp:textbox ID="mybox" Runat="server" Width="20"></asp:textbox>
VB NET code:
Private Sub SetFocus(ByVal ctrl As System.Web.UI.Control)
Dim s As String = "<SCRIPT
language='javascript'>document.getElementById('" & ctrl.ID & "').focus()
</SCRIPT>"
Page.RegisterStartupScript("focus", s)
End Sub
Now when I run the page and go to the Zip code <input> box, it calls a
server side routine and within that routine I call the SetFocus as:
Me.SetFocus(Me.mybox)
It causes a javascript error that says 'document.getElementByID(...)" is
null or not an object.
I looked at the html after entering something in the zip code <input> box
and I see the following inserted at the bottom of the page just above the
</form>
<SCRIPT language='javascript'>document.getElementById('mybox').focus()
</SCRIPT>
I know I'm close but I just don't know why I'm getting the "is null or
not an object error".
And....I want to say thanks to David for all his excellent help!!!!!

Sheesh...I got it to work by changing parts of the <SCRIPT> as follows:
Dim s As String = "<SCRIPT language='javascript'>document.getElementById
('" & ctrl.ClientID & "').focus(); </script>
so I changed ctrl.ID to ctrl.ClientID and then I put a ; after the focus()

Ouch! Now I have the server side focus working. It works great on aspx
pages with no controls or only one control. It doesn't work so well on
an aspx page with multiple controls.
I have such a page with multiple controls that I simply manipulate by
using the visibility element.
When the first control is made visible, I load the focus to set my cursor
to the first input box. It works great and puts the javascript code at
the bottom of the html.
Problem is, when I leave that control and load another, that old
javascript code remains when the new control page is loaded and I error
out because the original input box is not part of the new control.
Is there a way to get rid of that javascript put at the bottom of the
page via the "Page.RegisterStartupScript("focus", s)" before the new
control is loaded???
Thanks...Jim!!!

Subject: [aspx] RE: <input> box focus
Sheesh...I got it to work by changing parts of the <SCRIPT> as follows:
Dim s As String = "<SCRIPT language='javascript'>document.getElementById
('" & ctrl.ClientID & "').focus(); </script>
so I changed ctrl.ID to ctrl.ClientID and then I put a ; after the focus()
Thanks again everyone...and especially David!!!
