Using Framesets in WC5 vs Altering Grids

Does anyone have any good examples illustrating how WC5 has been combined in a successful and elegant way? I had tried to set up a traditional WC web form where I set up my own DIV tags to split the page with a wwWebDataGrid to illustrate results on the right side of the page, driven by a panel of different analytical conditions on the left.

Problem is each analytical method requires a different grid matrix design on the right hand side; I tried to manipulate the matrix programatically but it did not seem to hold; removing and adding columns seemed to lose the reference and the like, so, I thought that using framesets would be better.

I understand that using Frames and Framesets have been taboo; does anyone have any other recomendations? I've been messing with toggling the grid visible or not, but I can't seem to alter to grid characteristics on the fly. The Grid's load properly and the right data is always presented, however, can't modify the nature of the table...

For example, I have tried to modify the grid headers on the fly, depending on the new data cursor, but, whatever modifications I have tried tend to fail; does anyone see what I am doing wrong here in terms of altering Grid Characteristics on the fly; I figure that you should be able to modify this without to much difficulty but my grid references appear to be pooched...

Some Code below;
