For looping through the inner grid, you can use the below code (when clicking on a button)

gvMainGrid is the parent grid
gvInnerGrid is the child grid

Using the below code you can loop through any controls.

C#

protected void btnUpdate_Click(object sender, EventArgs e)
       {
           for (int i = 0; i < gvMainGrid.Rows.Count; i++)
           {
               for (int j = 0; j < ((GridView)gv.Rows[i].FindControl("gvInnerGrid")).Rows.Count; j++)
               {
                   ((TextBox)((GridView)gvMainGrid.Rows[i].FindControl("gvInnerGrid")).Rows[j].FindControl("txtSNo")).Text = "100";

               }
           }
       }

Hope this will help you.
