Error when trying to load a user control dynamically

Question

User2068649013 posted

I'm trying to load an embedded user control.

The user control is embedded to a .dll. Following code is used to load the control.

UserControl myCurrentControl = (UserControl)LoadControl(@"~/MyControls/CustomControls.dll/MyCustomControl.ascx");

The issue is this same code working when the project was a Web Site, now I have converted it to a Web Application and this gives the error file cannot be found?

Am I still referring to the correct location or in Web Apps do I have to load the dll from a different location?

Please help.

If it's in dll, you can just instantiate the instance of UserControl

UserControl myCurrentControl = new MyCustomControl();

Agree！

My addition is that you should refer the dll into your proj before you wanna use that……

Thanks for the replies, I found what went wrong. This user control is embedded to the dll by setting it's property Build Action to Embedded Resource.

The problem was with my virtual path provider. I had to register the virtual path provider in "Application_Start" method in Global.asax. In my working web site it was done in AssemblyResourceProvider in App_Code. When converting Web site to Web App since theres no App_Code in web app this whole code was missing.
