I made the changes recommended by the documentation you referred me to and the problem still exists. I have add the new .aspx code plus the new code behind. I think you folks have a true bug here unless you can provide me with specific changes I can make that will correct this.
First, I have attached 2 additional screen captures that show what happens when it is wide, and what happens when it goes narrow (responsive).
Second, my .aspx file source code for the grid placeholder is immediately following and then the code behind source follows that.
If you should have specific recommendations you can make instead of just pointing me at documentation, I would be most interested in seeing them.
