VS2008 Designer

[ikari]

Hello,

I have a control which works perfectly in VS2005, but in design-time
is broken in VS2008.

The control renders as an image, and the output tag for the designer
is simply an <img> tag.

I have checked to ensure that the output of the image, and the tag,
are correct.

However, what shows up in VS2008 design time is what looks like a
bunch of squares before the actual image. These squares seem directly
coorelated with the inner properties of the control: i.e. if i remove
the inner properties from the .aspx then the squares go away, but of
course, then the control doesn't have any of its properties set.

The squares look like characters that cannot be processed. Clicking on
these squares will select the control, which is very odd.. It is
clearly a VS2008 designer issue, but I was wondering if anyone knew
how to get around it, or had any experience with it?

Thanks.
