Fixed columns in grid?

My personal app is able to return a JSONObject of data rows and includes a dynamic set of columns. Looking at the DHX 6 Grid documentation, it appears that the user must “hardcode” the column info (number of columns, column data type). Is there a way to just infer the column info from the actual JSON data file?

It doesn’t seem so, as you have to match the “id” to the index of the array. I wouldn’t expect an official answer on this any time soon - they don’t seem to be providing support yet.

You’re right. Unfortunately the config of the grid cannot be defined right in the data section.
You need to define the columns of the grid before loading the data to it.
