I'm sure that this is a simple problem, but it is making me crazy. Whenever I insert a textbox,listbox, or any control onto my ASP page in design mode, it looks fine. As soon as I view this same page in my browser, these same controls are missing. I did notice that information inside the texxtbox is visible.<BR>Hopefully, this makes sense to someone out there.<BR><BR>Davidrmif the textbox is white and you have white background on your page it might not be visible try to set a border on your textbox like this: style="border: 1px solid" bordercolor="#000000"Thanks for your help,Freddie<BR>I found that one of the dll's was not registered from the .net framework installation. Basically, I would have always had problems with asp.net. I got it figured out.<BR><BR>DavidI am having the same problem - on two different computers. I see the controls in the designer but not in the browser when running. I changed the borders - that didn't help. What DLL was not registered? How did you determine this? Does anyone have any other ideas? [email protected] here. I am also not able to see many of the controls. I am running Windows XP Pro. I'd also like to know what DLL was not registered.Found this link that helped me out. I guess I should upgrade the .NET Framework SP 1 also.<BR><BR>http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsdebug/html/vxtbsHTTPServerErrors.asp
