Hide templatefield column in gridview if column is null or 0

Question

I need some assistance. I have a gridview and there are times that its column is null. When it's null, I want to hide that specific column. Please see pix below:

 

 

 

This is what I started but the result is not nice. Sometimes it disappear and sometimes it doesn't. Worst is, even the column that has value sometimes disappears also. 

 

Thanks for any assistance.
