I'm sure it's possible, but it hasn't occurred to me "how" to set the values
of the <body> tag via code-behind. I am currently setting the onload event i
n
the body tag of an ASP.NET web form using old-fashion asp type <%.. code...
%> blocks.
This "spaghetti-scripting" is difficult to manage, and is essentially a
hack. And, i cannot view the HTML in DESIGN view, only CODE view. Which
further causes problems when i try to wire events.
I tried, for example, to embbed an <asp:label /> and other controls in the
<body> tag, but VS.NET doesn't let me (probably for good reason too).
Anyone have ideas?

Give the body an id and a runat=server. For example <body id=body1
runat=server>. In codebehind (vb) put
Protected body1 as htmlgenericcontrol in your declarations. Then you can set
any attribute that you can set in html. Here is an example of setting the
onload attribute.
body1.attributes("onload") ="java script:doSomething();return false;"
Mike
throw a RUNAT=SERVER in it and declare it in the codebehind. It should
work...

Mark <body runat=server id=_body> then manually in your codebehind add:
protected System.Web.UI.HtmlControls.HtmlGenericControl _body;
And then you should be abe to use _body.Attributes.Add() and any other API
to modify the element.

Newbie: parser error when using a Literal tag
Here goes.. I'm starting with a working application and am trying to make some modifications and things aren't going well.
I think you're confusing the parser with nested tags. Try to make stylesheet a string instead of a literal and inject its value using <%= %>.
Even better, make the LINK tag runat=server (and declare it as a HtmlGenericControl in the code-behind) and set its properties using the Attributes collection.
Thank you both, its working now. I am making the link runat=server.
I wanted to add a Literal tag to a page like in this article:
http://www.odetocode.com/Code/82.aspx
But I keep getting a parser error on my page:
Parser Error Message: The base class includes the field 'stylesheet', but its type (System.Web.UI.WebControls.Literal) is not compatible with the type of control (System.Web.UI.HtmlControls.HtmlGenericControl).
Here's my code:
-- from .aspx:
<LINK href="http://links.10026.com/?link=<asp:Literal id="stylesheet" runat="Server" />" type="text/css" rel="stylesheet">
-- from .aspx.vb:

Dim uc As Control = Page.LoadControl("UserControls/Login.ascx")If Not Request.IsAuthenticated Then
PlaceHolder.Controls.Add(uc)
lblUserLoggedOn.Visible = False
lnkLogOff.Visible = False
Else
Dim UserDetails As myCompany.BusinessLogicLayer.UserDetails
UserDetails = Session("UserDetails")PlaceHolder.Controls.Remove(uc)
If Not IsNothing(UserDetails.UserName) Then
lblUserLoggedOn.Text = "Currently logged on as " & UserDetails.UserName
Else
lblUserLoggedOn.Text = "Authenticated but logged on as NO-ONE!"
End If
lblUserLoggedOn.Visible = True
lnkLogOff.Visible = TrueEnd If
If Not IsPostBack Then
dlEvents.DataSource = EventsTable.GetList
dlEvents.DataBind()dgClinics.DataSource = ClinicsTable.GetList
dgClinics.DataBind()Dim OrgName As String
OrgName = Session("org")
If OrgName = "" Then
OrgName = Request("org")
End If
If OrgName = "" Then
OrgName = "foo"
End Ifstylesheet.Text = OrgName & "/styles.css"
End IfEnd Sub
I would have snipped the code-behind, but I figured I'd end up snipping the offending line... I'd be happy to provide more info if required.
J<LINK href="http://links.10026.com/?link=" type="text/css" rel="stylesheet" id="stylesheet" runat="server" />
Protected WithEvents stylesheet As System.Web.UI.HtmlControls.HtmlGenericControl' code:
stylesheet.Attributes.Add("href", "whatever value")
I think you're confusing the parser with nested tags. Try to make stylesheet a string instead of a literal and inject its value using <%= %>.
Even better, make the LINK tag runat=server (and declare it as a HtmlGenericControl in the code-behind) and set its properties using the Attributes collection.
Thank you both, its working now. I am making the link runat=server.
And when I took the literal out of the <link/> it also worked, so at least I know what the problem was!
Cheers,
J
