Upgrading issues

[rsweeney5]

I have been working on a .net site using Phalanger 2.0 on and off for some time, up to the point when I changed to 3.0 everything worked fine. After the first installation (of 3.0) I ran into the error the Sample ASP.net site has so I went back to the Dec release and some of the pages are fine, but many of them are giving me errors like "Unable to cast object of type ??? to type ??? ,the errors seem to be endless.

Heres one example:

Code: Select all

Unable to cast object of type 'System.Web.UI.WebControls.Button' to type 'System.Web.UI.WebControls.LinkButton'.
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.

Exception Details: System.InvalidCastException: Unable to cast object of type 'System.Web.UI.WebControls.Button' to type 'System.Web.UI.WebControls.LinkButton'.

Any thoughts on where the problem may lie? Should I just go back to 2.0 where I know it works, or might it be a configuration problem? Any insight or thoughts would be great.

Hi,

did you try to clean ASP.NET Temporary files?

Code: Select all

%WinDir%\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
%WinDir%\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files

I can't see any usage of LinkButton in the code. So it seams to me there is some old compiled code not being refreshed?

[rsweeney5]

I will be sure to try that at my next upgrade attempt for now I just reverted back to the old version, but I appreciate your thoughts and will give it a shot if it comes up again.

There was no reference to linkbutton in the code nor the function that was called from the button, eventually I did find that I could use only onClick events from asp:Linkbutton and onCommand events from asp:Button which I found odd.
