How/Where to add to the BODY TAG

T

tony obrien

Hi ,

I'm trying to add an "OnLoad=blahblah.setFocus()" thingy to an ASPX page.

Is there a PAGE object (or something) that allows me to add to the BODY tag
that finally gets rendered?

thanks,
tob

Hi,

You'd specify the BODY tag with an ID and runat="server" attributes which
gives you server-side access to the control (which it is after it has those
declarative attributes ). You could then have a codebehind member for it
with type System.Web.UI.HtmlControls.HtmlGenericControl (or
HtmlContainerControl), which you can use to access the attributes of the
control

But in codeBehind if I "Dim aNewBody as HtmlControls.HtmlGenericControl"
then set its "InnerText" value to somehting like:
"ID="myBody" runat="server" bgColor="#fffffff" onLoad="someItem.setFocus
();"


How does ASPX knwo to replace the "original body" with mine??

its seems that there is no connection between the two using
HtmlControls.HtmlGenericControl ??

Hi,

the code-behind member name must match to the ID you give to the control.

Use this tag:
<body ID="myBody" runat="server" bgColor="#ffffff">

Use this codeBehind:
Dim myBody As HtmlControls.HtmlGenericControl

The name "myBody" connects the two.

Then use this in your code:
myBody.Attributes.Add("onLoad","someItem.setFocus();")

Thanks... I think I'm close. here's what I've got (but doesn't work ;)

I added .. id="myBody" runat="server"
to the basic page.

Then in codebehind I have....

Dim newBody as new HtmlGenericControl
newBody = Page.FindControl("myBody")
newBody.Attributes("OnLoad") = "someItem.SetFocus();"


I can't find a list of the 'attributes' available for the BODY TAG, but I
have a feeling this is not working because the Attributes method does
recognize the "onLoad" ?

Can you help?
thanks,
tob

Thanks, Jos.

I understand the concepts and connections but it still doesn't work.

Here's an new aspect you may have missed... the "something" I'm trying to
set focus to was pushed into a PLACEHOLDER.

So my thinking was that the <body> was THE place to set the focus since by
this point the browser has complete control, the object has to exist, etc
etc etc.

Other attempts trying to use Javascript in PAGE_LOAD, and elsewhere always
brought an error saying essentially ("We ain't got none of those on this
page!")... meaning the render had not taken place fully enough for the item
to even exist on the page yet.

I don't get any errors from your suggestion but the item still does not
receive the focus when the page has finished loading.

Does the PLACEHOLDER notion change anything you've suggested?

thanks, again

ANd should I be "seeing" this new attribute in a ViewSource window from the
browser? I am not.

Well, here's the answer.... given Jos' suggestions and some misspellings on
my part (Argh!), It STILL didn't work UNTIL I also turned off
"SmartNavigation"

I guess it overrides the ".focus()" and forces the page to be qhere IT
wants it to be.

Now the focus goes EXACTLY as Jos predicted.

Thanks, to all.
