How to disable GridTemplateColumn link button Client Side?

[RJ]

Hi All,
Just wondering how can I disable Template Column Link button on Client side.
I wanted to change color, change cursor to default, not clickable and wont go to its link.
My code works for other databound column but for this template only through';
is working, all the rest is not applying at all.
Any info would be much appreciated.
Thanks in advance.

ASPX

<telerik:GridTemplateColumn HeaderText="Name" SortExpression="NAME" UniqueName="Name" HeaderTooltip="Name" DataField="NAME" HeaderStyle-Width="25%" ItemStyle-Width="25%" Exportable="true">
   <ItemTemplate>
      <asp:LinkButton id="lnkName" ForeColor="Blue" runat="server" Text='<%# Convert.ToString(DataBinder.Eval(Container.DataItem, "NAME"))%>' CommandName="LAUNCH_NAME" CausesValidation="false"></asp:LinkButton>
   </ItemTemplate>
</telerik:GridTemplateColumn>

JS

function isTaskNA(chk,idx) {
var chkNA = document.getElementById(chk);
var masterTable = $find("<%=GrdMain.ClientID %>").get_masterTableView();
var PN = masterTable.get_dataItems()[idx].get_cell("Name");
var row = masterTable.get_dataItems()[idx].get_element();
   if (chkNA.checked){
   row.style.color = 'gray';
   row.style.textDecoration = 'line-through';
   row.style.fontStyle = 'italic';
   PN.style.ForeColor = 'gray';
   PN.disabled = 'disabled';
   }else {
   row.style.color = 'black';
   row.style.textDecoration = 'none';
   row.style.fontStyle = "normal";
   PN.style.ForeColor = 'blue';
   }
}

How to remove this. On my first post there was an error so I created another thread and now it doubled.

The other thread has been removed. Anyone has idea or workaround on this issue? Thanks again.
