Reference body tag from code-behind?

tshad

In VS 2003, I am trying to set the onload property of the body tag to "". I
do this all the time from my Dreamweaver pages (one page aspx page). But in
a code-behind page I need to set a reference. How do I reference the <body>
tag?

I have the <bodyset as:

<body id="myBody" onload="document.forms[0].Textbox3.focus()">

I change this as:

myBody.Attributes.Add("onLoad","");

I get the error:

The type or namespace name 'myBody' could not be found (are you missing
a using directive or an assembly reference?)

I realize that I need to add a reference and tried to do:

protected System.Web.UI.HtmlControls.Body myBody;

I get the error:

The type or namespace name 'Body' does not exist in the class or
namespace 'System.Web.UI.HtmlControls' (are you missing an assembly
reference?)

What would the reference be?

Thanks,

Tom

Ahem...

<body id="myBody" runat="server"
onload="document.forms[0].Textbox3.focus()">

You're right.

I missed the runat attribute. Fixed that.

But that doesn't help the reference problem. I still get the error.

Dear Tom

I don't think it's possible because, as the error message points out,
there isn't a class in System.Web.UI.HtmlControls representing it.

In other words Microsoft have not provided any mechanism to access the
<body.. </bodyelement of the web page programmatically.

To be honest I don't see why this should be necessary. You probably
need to think about the approach you are taking in your solution. There
must be an easier and more direct way of carrying out the task using
normal web server controls.

Also try an HtmlGenericControl. There is no html control specific to the
body tag...

take this out of the body tag:

onload="document.forms[0].Textbox3.focus()"

assign onload event programmatically as needed

Apart from the HtmlGenericControl object, of course... :-)

The declaration for the reference should be:

protected System.Web.UI.HtmlControls.HtmlGenericControl myBody;

If you declare it with any other class, it will not be recognised as the
same object, and you will just get a reference that is not attached to
anything.

It is necessy as I am using the body tag to put focus on a textbox when the
page loads. But I need to change the onLoad event to either disable it or
jump to another control as I am hiding the control on the screen after the
initial Page_load.

As I mentioned, this is no problem in a single page design. But if there is
no way to do this using code-behind then this is just another reason why I
am glad I normally build my pages using DW instead of VS.

Thanks,
