HttpContext.Current.Server.Execute returns fixed width textboxes

Hello Group,
I am using 3.5 .NET VB.  In a code behind I am calling a page using this approach:
HttpContext.Current.Server.Execute("Survey.aspx").
On the survey.aspx page I have several textboxes are varying sizes.  If I run the survey.aspx page alone, the textbox appear on the screen in the correct size settings. However, when I use the HttpContext.Current.Server.Execute method to execute the survery.aspx page from another page, the textboxes always come back a fixed width of like 200px or so.  It doesnt matter what I change the size of the width to in the survey.aspx page, they are always rendered the same size for every textbox on the page.  The changes do show up if I view the survey.aspx page alone though without calling it through another page so I know my syntax for changing the width settings is correct.
Does anyone have any idea what causes this and how to resolve it?  I am stumped.
Thank you for any help
