I am having two grids, grid 1 showing the first table. Now if i clicked on 1st item. I should see the second grid with only t1_id == clicked item.

Both are UI grid

When i am clicking on an item it call the controller with parameter id. Now how can i filter the other grid with this id?

Answer 1

I found the solution To use session. What i observed was the constructor of the collection was getting called 3 times, this were erassing the data of request params.

Answer 2

As you mentioned you have UI grids, means in the second grid you must have a Dataprovider, you can check there if there is a, id available in the post then you can filter(by using addFieldToFilter() ) it according to id or will show all the data.
And, as you mentioned you have two tables then you can also put a join(by using getSelect()...) to fetch data from both the tables.
