Validating controls of Editable GridView using Javascript

When you have a GridView with editable controls like TextBox,CheckBox etc it becomes necessary that you validate the controls before clicking update.I am sure there could be different ways to access the controls in GridView.Here I am posting  how it is done without hitting the server side using javascript.

<EditItemTemplate> <asp:LinkButton ID="lbkUpdate" runat="server"
 OnClientClick='javascript:return Validategrid(this);' CausesValidation="True" CommandName="Update" Text="Update"></asp:LinkButton> </EditItemTemplate>
 function Validategrid(btnCtrl)
{
var gridView = document.getElementById('<%= grd1.ClientID %>');
var selectedRowIndex = btnCtrl.parentNode.parentNode.rowIndex;
var txt1 = gridView.rows[parseInt(selectedRowIndex)].cells[0].children[0];
var txt2 = gridView.rows[parseInt(selectedRowIndex)].cells[1].children[0];
var chk1 = gridView.rows[parseInt(selectedRowIndex)].cells[2].children[0]; ;
var chk2= gridView.rows[parseInt(selectedRowIndex)].cells[3].children[0];

 if (chk1.checked == false && txt1.value == "" && chk2.checked == false && txt1.value == "")
  {
                                                                            
   alert("Please provide inputs");
   return false;
  }
           
  }
