Populates GridView2 based on selected row from GridView1

Question

Greetings! Help with gridviews. I have 2 gridview on my page: on GridView1 I have a column with select link, Id and Name which looks like this:

Select | Id | Name

select | 101 | Jack

select | 102 | Cath

Now, what I am trying to do is let's say, i clicked the select from the first row which is Jack, now my GridView2 will display the products ordered by Jack which looks like this:

Id | ProductID

101 | 111

101 | 222

101 | 333

and if Cath whom I selected, GridView2 will change the display products which ordered by Cath:

Id | productID

102 | 111

102 | 333

102 | 555

In short, I am trying to populate GridView2 based on the selected row from the GridView1. I am using asp.net with c#. Kindly help me with this, thank you very much in advance. God bless :)
