Move from one page to another while saving selected options

Hi,
I created an app looking to:


With a lot of other multiselects.
I use the two-option radio button to address two different needs.
My question is how I can save a selection when I move from one tab to another to not redo it when I go back.
I tried a lot of solutions around the use of SessionState but I didn’t succeed.
If someone can help it will be great!
Thanks

Hi synode,
Many thanks for your quick feedback.
I am trying to implement the solution but I have on problem.
My two pages have the same options.
the only difference between the two pages is only on the source database.
I suppose that I have to make all options names unique in order to store their state.

Hi Synode,
After some numerous tests I got what I want using your class object.
many thanks,
