Dynamic HTML from Code Behind

Dec 7 2017 11:19 AM
Hello, I have inherited some C#.NET code that builds a dynamic dashboard on page load. The dynamic dashboard consists of a table and 2 rows - one row showing online devices, the other row showing offline devices. My issue is that if there are more than 5 devices on a given row, the row gets cluttered and looks terrible. I would like to break the line at 4 devices, but I am so confused by the logic. I have spent the last 48 hours swirling through this code and trying to find where to break the line and how - I am still lost. Please, any help would be very much appreciated. Please see a snapshot of the code below. Thank you so much in advance. -Jason
