How to select the 1st row in grid on page load and bind the second grid

[Dorababu]

I am doing a task Master-Detail, for this I have taken two grids where I will initially bind a grid view at this point I would like to select the first row and display the corresponding details in the second grid view. Like that when I select the later I would like to bind the corresponding details.

Sample data in my database

Table1

EmpID  FedID
   1        1234
   2         6546

Table2 

EmpID  Name
   1        ABCD
   2         EFGH


Initially I would like to load the first record details in the second grid view and show .

Means on Initial page load I will show the Table1 data in gridview1 immediately I would like to show the second grid view as follows

EmpID    Name
  1           ABCD

I would like to achieve this from server side code
