timer

I have a grid that I want to bind every X seconds, but the timer is not waiting until the process is done, it's just executing itself over and over, I even tried creating a variable, and use it as a flag, but it doesn't seem to be working, here is my code(the problem is not in my code behind, if there's any problem it has to be here, because the only thing i do is bind the grid in the tick event):
