Disable button (in data list) after one click by user

I want to disable a button contained in a data list row. Is it possible to disable the button after the user has clicked once by the user? If yes, please ask someone to suggest how I can achieve this.

<asp:DataList ID="DataList1" runat="server" DataKeyField="Qno" OnItemCommand="DataList1_OnItemCommand"
        DataSourceID="SqlDataSource1">
        <ItemTemplate> <asp:RadioButton ID="RadioButton1" runat="server" Text='<%# Eval("Ans1") %>' GroupName="qu" />
            <br />
            <asp:RadioButton ID="RadioButton2" runat="server" Text='<%# Eval("Ans2") %>' GroupName="qu" /> <asp:Button ID="Button2" runat="server" Text="Submit" CommandName="Validate" />
            <br />
        </ItemTemplate>

I have nothing to do with ASP, but if you want javascript (jQuery) then you can just do something like

$(.once-clickable-button).click(function(){ 
  $(this).attr("disabled", "disabled");
  // if needed - do what it is supposed to do
});


(of course add to the button "once by pressing the button" or choose the name that suits you)

<script type="text/javascript">
   function checkEnableSubmit() {
     document.getElementById("Button2").disabled = true;
   }
</script>


call this method on onclick event when you want to disable button

With javascript, you can do something like the following:

document.getElementById("buttonID").disabled = true
