Data missing when exporting gridview to txt file
Question
I am exporting 3 columns. AppID, Credit File and Creation Date from a Gridview but when I open the file the only thing I see is AppID and Creation Date. The Credit File data is missing. I tried just exporting the credit file itself but that just showed the header but again no text.
here is my html

I was able to fix this by removing the ItemTemplate Field
