"Failed to map the path" - error on first visit

hi,

I have a repeater which dynamically loads another usercontrol throught
databinding:

OnClick: DataBind()

rptProduct_ItemDataBound: ViewSmall _viewSmall = (ViewSmall)
LoadControl("ViewSmall.ascx");

The two UserControls are in the same directory on the server.
The webroot for this application is c:\inetpub\wwwroot\joa\InfoCenter\Test
and the usercontrols are placed in
c:\inetpub\wwwroot\joa\InfoCenter\Test\DesktopModu les\Csite.Product\ViewSmal
l.ascx

I get this error the first time I click this button after recompiling my
project - but only the first; all subsequent clicks, reload or whatever,
finds the UserControl and displays everything correctly:
Failed to map the path
'/InfoCenter/Test/DesktopModules/Csite.Product/ViewSmall.ascx'.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Hi Jonas,

From your description, you're dynamically load one Usercontrol in a
webpage's repeater control's databinding event , but you got "Failed to map
the path" error every the first time you fire the databinding, yes?

After viewing the error info and call stack you provided, I'm also feeling
very strange since the absolute path asp.net is locating the control is
correct according to your description. That's the
'/InfoCenter/Test/DesktopModules/Csite.Product/ViewSmall.ascx'
and /InfoCenter should be the site root ,yes?

And as to narrow down the problem, I think we can try performing the
following test:
1. Create a new simple page and load the Usercontrol dynamically to see
whether there has the same problem.

2. If #1 hasn't any problem, try adding a repeater or datalist and
dynamically load the control in the template databound control's
databinding event to see whether the problom will occur.

In addition, based on searching in the former issues , there is some issue
mentioned that sometimes when the usercontrol's ascx templatefile is
locked by something it will popup "failed to map the path" error. So we can
also have a check to see whether there're any other programs which may lock
the usercontorl file.

If you have any other findings, please also feel free to post here. Thanks.

Regards,
