Doing something stupid here but cant figure it out, simple page with a grid on it pulling data from an object data source. Stored proc works and brings back columns I expect as listed in the markup

But get:

Value cannot be null.
Parameter name: key

Hey Jon,

I am seeing the same issue after updating the ASP.NET AJAX to the Q2 2015 build yesterday. Any page with a RadGrid instance on it will throw an error. I assume there is a bug in the new build and reverted back to the Q1 2015, which works fine.

Hope you get a reply soon from their support staff!

Hi,

Note that this problem is already fixed and the fix is included in the previous internal build and will be part of the upcoming SP1.

Hi Ralf,

The Q2 2015 SP1 is scheduled for July 29 and if everything goes as planned, the SP1 should be available for downloading then.

Once again, please excuse us for any inconvenience caused by this.
