how to validate gridview row in java script on button click

Hi,

Assume that GridViewCTInformation id ID of gridview and txtName is ID of textbox which is present inside your gridview.

Javascript

function gvValidate() {

var grid = document.getElementById('<%= GridViewCTInformation.ClientID %>');

if(grid!=null)

{

var Inputs = grid.getElementById("<%= txtName.ClientID %>");

if (Inputs[i].value == "") {

alert("Enter values,blank is not allowed");

return false;

}

<asp:Button ID="btnValidate" runat="server" Text="ValidateGrid" onclientclick="return gvValidate()" OnClick="ServerButton_Click"/>
