I have a web application that was developed in Visual Studio 05 in a 32bit Win XP environment a few years ago without any issues. Currently, I'm running VS 08 in a Win7 64 bit environment and need to make a minor modification to the web application but
am receiving a build error on the following control:
Error: 'AjaxControlToolkit.ModalPopupExtender' does not contain a definition for 'ChangeVisibility' and no extension method 'ChangeVisibility' accepting a first argument of type 'AjaxControlToolkit.ModalPopupExtender' could be found (are you missing a using
directive or an assembly reference?)
Not sure why this is happening even though all related references have been made in VS 08.
Any recommendations or suggestions would be most appreciated.
Thank you in advance.

If you are using the above code to show the Modal PopupExtender then you can use the below code
//Show the modalpopupextender
//Hide the modalpopupextender

Yes, that was the solution, thank you again.
