  In first page source code write code in Script as
  <script type="text/javascript" language="javascript">
  function getId(ControlId,UserName)
  {
  document.getElementById(ControlId).value = UserName;
  }
  </script>
  ......
  and next go to .cs of same page and write code as
  protected void Page_Load(object sender, EventArgs e)
  {
  lnkbt.OnClientClick = "window.open('GridView.aspx?ControlId=" + txtName.ClientID + "')";
  }
  
  protected void Button1_Click(object sender, EventArgs e)
  {
  Response.Write("<script>alert('Hai')</script>");
  }
  ...........
  Go to next page and write below code in source code as
  <script type="text/javascript" language="javascript">
  function getData(ControlId,UserName)
  {
  window.opener.getId(ControlId,UserName);
  window.close();
  }
  </script>
  ................
  next go to .cs of this page 2 and write code as
  protected void Page_Load(object sender, EventArgs e)
  {
  DataTable dt = new DataTable();
  dt.Columns.Add("UserId");
  dt.Columns.Add("UserName");
  dt.Columns.Add("Password");
  dt.Columns.Add("EmailId");
  
  dt.Rows.Add("1", "Ravi", "Ravi", "Ravi@gmail.com");
  dt.Rows.Add("2", "Rama", "Rama", "Rama@gmail.com");
  dt.Rows.Add("3", "Ramu", "Ramu", "Ramu@gmail.com");
  dt.Rows.Add("4", "Rao", "Rao", "Rao@gmail.com");
  
  
  
  GridView1.DataSource = dt;
  GridView1.DataBind();
  }
  
  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
  {
  LinkButton lnkSelect = (LinkButton)e.Row.FindControl("lnkselect");
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
  lnkSelect.OnClientClick = "getData('" + Request.QueryString["ControlId"].ToString() + "','" + e.Row.Cells[1].Text + "');";
  //lnkSelect.OnClientClick = "test();";
  }
  }
  }

  Actually in this senario when we run the program and click on a button it will redirect to other page with in the window ie a popup box.In this window if we click on any row of gridview column then this window 2 will close and id will display in page 1 at textbox.
  I think so this is correct answer .
