Unable to generate code...

[A Traveler]

Hello, i am having this problem. The exact error message is:

"Unable to generate code for a value of type 'System.Web.UI. Page'. This
error occurred while trying to generate the property value for Page."

After a lot of googling, all i can find that this applies to is when trying
to use enum-type datatypes as bit-vector flags, or when use designers to
make an expandable property in the property tool-window. However, NEITHer of
these cases apply to my page. This is only happening on one page in the
project. But the stack trace of the error (included at the end) gives me no
hint of where to even start looking to fix it, of WHAt exactly might be
wrong with the page.

Thanks in advance,
- Arthur Dent.

Well, i finally figured it out, after a day of piece-by-piece rebuilding my
page.

I had a TD tag in my html code which i set to runat="server". I then added
on an attribute named "page" where i was going to keep track of the custom
page my grid was on (im paging by alpha-filters instead of numeric page
numbers). When the page tried to render this control though, it was now an
HtmlTableCell object, which has a Page property (derived from Control
class). It thought i was trying to set that property = "" and it got all
confused. By simply changing the name of my custom attribute from "page" to
"pageindex" , it works again. Apparently on a runat=server HTML tag, the
framework will try to interpret any attributes specified as .NET Properties
first, and if there isnt one by that name, then it treats them as HTML
Attributes.

CheerZ.
