We recently updated our ASP.NET AJAX controls from version 2012.03.1017.0 to 2013.02.717.0. Something that I noticed is that a telerik:GridBoundColumn with Visisble="false" would still bind and be accessible from the code behind with the older control, but no longer binds with the new control. Is this a known change or perhaps an unintended side effect?
By the way, the fix for this in our case was easy- we simply used a datakey instead of a hidden bound column.
Thank you.
