Hello Sandeep,

You are not able to get Visible="false" column value on client side.

But you can achieve your requirement by using DataKey.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
       <script type="text/javascript">
           function ButtonClick() {

               var grid = $find("<%=RadGrid1.ClientID %>");
               var MasterTable = grid.get_masterTableView();

               var Rows = MasterTable.get_dataItems();
               for (var i = 0; i < Rows.length; i++) {
                   var row = Rows[i];
                   alert(row.getDataKeyValue('ID'));
               }


           }

       </script>
   </telerik:RadCodeBlock>

.

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
       >
            <MasterTableView DataKeyNames="ID" ClientDataKeyNames="ID">
                <Columns>
                    <telerik:GridBoundColumn DataField="Name" HeaderText="Name">
                    </telerik:GridBoundColumn>
                </Columns>
            </MasterTableView>
        </telerik:RadGrid>
        <br />
        <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return ButtonClick(); return false;" />

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
      {
          dynamic data = new[] {
            new { ID = 1, Name ="name1"},
            new { ID = 2, Name = "name2"},
            new { ID = 3, Name = "name3"},
            new { ID = 4, Name = "Name4"},
             new { ID = 5, Name ="name5"}};
          RadGrid1.DataSource = data;
      }
