Hello,
Can someone please help me with this error I got when the row_editing event of my gridview fired and validated my data entry fields such as textboxes, dropdownlists, etc? I am using required field validators to validate my controls and asp validation summary to provide a summarized error message of all required validators within my page.
I don’t know why this particular error occurred but I know it has something to do with validation since after I removed the validation in all controls, I got no errors. However, I really need validators on my page since it is a requirement in the project so I need to sort this error out. Please see the image below for the exact error message.

Hello,
The problem you are encountering may be a result from trying to browse an asp.net application. However the possible scenarios of this error are
1. When you are creating a new web application using visual studio it tends to create a virtual directory and configures it as an application. But when you manually create a virtual directory and it has not been configured, then you encounter this error.
To resolve this, Right click on virtual directory and go to properties. Then click on Create. This will automatically create the ‘application’.
2. When there is sub-directories in the application, you can have web config file in the concerned directory. These files have settings that cannot be overridden and we encounter this problem.
