I am not sure if I understand your scenario completely. However the main issue that you need to solve when you do not have specific model is to define the columns of you Grid - this is usually solved by looping through the dynamic collection which holds the information about the columns and defining them through the string overload of the columns builder.
here is a really simple scenario using a for loop:
for (int i = 0; i < 23; i++)
Make sure that you have checked our code libraries
which might show similar setup to what you need.
