Themes not working sometimes.

I am setting the src of a Iframe in the page load like this:
fraContent.Attributes.Item("src") = "Splash.aspx"
and sometimes the themes do not work. The page displays in the browser but
the themes are not applied. The <link ... is on the page when I look at the
soruce.
Any Ideas.
Thank you,

JerryHello Jerry,
I do not have your source code to test on directly. But here are some
suggestions that, I think, deserve your trial.
1. Does the "<link _" links to the correct theme page when the themes are
not applied? Please pay attention to the relative path. In my best guess,
the theme page cannot be loaded because the relative path to the page is
not correct.
2. Is the line fraContent.Attributes.Item("src") = "Splash.aspx" inside the
if statement: if (!Page.IsPostBack) { _ }?
If that, when the page post-back occurs, the line
fraContent.Attributes.Item("src") = "Splash.aspx" will not be executed in
the Page_Load event handler.
We can debug the site in Visual Studio, set a breakpoint on
fraContent.Attributes.Item("src") = "Splash.aspx" and see if it is executed
every time when we need to load the theme page.
3. When the theme page cannot be loaded, what is the browser? As far as I
know, some browsers do not support html tags very well.
By the way, since ASP.NET 2.0, a new feature "Theme & Skin" has been
supported by ASP.NET. If your theme pages only contain style information,
I'd suggest using ASP.NET Theme, which is much easier to accomplish the
task. For more information about "Theme and Skin" in ASP.NET, please refer
to:

Jialiang,
Thank you for your reply. The problem only occurs SOME of the time so all
the links are about appying the themes and if the code was not correct the
themes would not be there ALL of the time not just SOME of the times.
Anyway.
I have fixed the problem. This does not explain why the problem occured in
the first place. I placed a system.threading.thread.sleep line in the
LoadComplete event of the page. this seemed like the same problem solved by
the waitForEvents in window forms.
Have you seen any of this kind of problem.
Thank you

Thought this would be simple

Thought I would work on setting certain UI elements dynamically. Sounded like an easy task until now. Any ideas how to resolve this error?

Also, Is there a way to populate the ddl1.items.add("") list within the code and not hard coding?Also, Is there a way to populate the ddl1.items.add("") list within the code and not hard coding?

I'm not sure what you're trying to do.
I'm not sure what you're trying to do.

Would help if I explained it more. Sorry about that. :blush:

I am trying to dynamicaly assign the BorderStyle from the value in a string variable. The following line blows up:

cellNew.BorderStyle = strBorder 'Bombs right here

In addition to that, when you manually assign "BorderStyle." intellisense pops up with the listed values:

Dashed
Dotted
Doubled
Groove
Inset
None
NotSet
Outset
Ridge
Solid

I want to capture those values and place them into a DropDownList with out having to hard code. Instead of doing it like this:

ddl1.Items.Add("Dashed")

Can I code it to auto populate those values?

Any ideas?
