When I initially go to the first page, the grid on that page works just fine. I then go to the 2nd page, and the grid there works fine too. However, when i go back to the first page, the grid doesn't work properly. For example, I get error messages from my refresh code that is assigning the controlsource properties of the columns. The messages say that colFilename is undefined. If I run this under the debugger and put a breakpoint in the Refresh method of the page I can see that the Columns collection is empty.

Does the same problem happen if you set up your grids in run-time?
