Enterprise portal for AX 2012: How to pass a value from one page to another?

I am having a listpage e.g, EPListpage1 for EP and displaying some values in it using available datasources.

Now, I have a page e.g., EPDatasetPage1 created on EP showing values based on a dataset created in AOT. EPDatasetPage1 is being accessed from EPListpage1 using menuitembutton.

I need to get selected value from EPListpage1 in EPDatasetPage1?

Already tried some methods on listpageinteraction class but without success.
