>Again, without understanding how the grid works fundmentally, then understanding how MVC works, you will not be able to just jump into a sample, start changing things the way you think they should work, and expect it to work. You have to go back to the sample app, get it working, then make small changes until it stops working and figure out what you did wrong.

The sample app (the one I downloaded) is working for me fine. My own (modeled from that app) also works fine. My minor changes (introducing a confirmation message to delete or fixing the flexgrid so it doesn't allow to put letters into pager control) also works fine.

But may be you're right and I better first try to change that sample app the way I want my app to behave then apply the same idea to my app.
