SharePoint Custom Application Page does not recognize tagPrefix defined in custom web.config
- by Hasan Khan
I have a custom application page integrated in Centeral Administration. My application pages are placed in a subfolder in Template\Admin folder. I placed my own web.config in my subfolder and added tagPrefixes in the control section.
However when I open my application page ASP.NET throws the exception that the tag SharePoint:InputFormTextBox was not recognized.
Moving the add tagprefix statements in root web.config solves the problem but thats not acceptable in my case and I can't define them in individual pages either.
What am I doing wrong? Or it doesn't work this way? What can i do to achieve this?
