Hello,
i have had a problem since last week and i don't know how to solve. I
searched into the forum but i didn't find a explanation for my
problem. If someone could help, i would be grateful.
I would like to load data into a PagingMemoryProxy but data are not
shown into the grid. There are only the spaces (lines) reserved for
data.
Please, the code is:
Code:
