Not to butt in, but are you sure you have the identical versions of the
control between the two machines?

Hello Jonathan,

Thanks for the response.

It is really strange that the problem doesn't happen on the other machine.
Based on my experience, I suggest you do the following steps:

1) Remove the web control and install it again on the system.
2) Reinstall VS.NET on the system.

I understand that reinstalling it is a time consuming task. However, there
is no public list of which file is responsible for IDE HTML view rendering.
So reinstalling is the most convenient way.

If the problem still can't be resovled, we may need to launch windebugger
and attach to vs.net when in operating. This may need the source code of
that web control. So I suggest you also consult it in Infragistics. You
could also contact Microsoft Product Support Service to have one support
engineer to work with you specificaly on it.

Please post here if there are any questions.

Best regards,

!This is correct.  On another machine that I have it is not
!doing it.  Standard web server controls such as the
!Datagrid work find and do not lose any information.

!Ok.  We may of had a little bit of a mis-communication
!here.  It isn't losing anything in the code-behind.  And I
!also don't think it is the fact that I'm trying to do
!anything too fast.  As soon as I open an ASPX file with
!this control on it, it opens and put an asterisk up beside
!of the filename like it does when you modify the file for
!the first time.  If I switch to the HTML view, it is
!missing some things between the tags.  If I hit Ctrl-Z
!(Undo) while in the HTML view, the code that was erased is
!restored.  As soon as I switch back to the Design View, it
!is erased.

!I did trying to repair the installation.  I let it go
!through and reinstall everything.  It is still doing the
!same thing.  I really don't want to uninstall completely
!and reinstall as it takes hours to reinstall.  I'm not
!sure of the DLL that the Designer uses and if that somehow
!may relate to Internet Explorer or Visual Studio 6 which I

!
!Let me know if I can provide anymore information to help
!solve this problem.
