Datalist_ID is the value of the ID attribute of your datalist

Javascript :
window.onload = function() {
      var selects = document.getElementById("<%= Datalist_ID.ClientID %>").getElementsByTagName("select");
     for(var i=0;i<selects.length;i++) {
            selects[i].onchange = function() {
                  this.disabled = true;
            }
     }
}

Open in new window

jQuery :
$(document).ready(function() {
      $("select", "#<%= Datalist_ID.ClientID %>").change(function() {
            $(this).attr("disabled", true);
       })
})

The id  of the datalist control is DataList1, and the dropdownlist's is id ddlMat. how can I use it in the page?

Thanks

Did you tried to replace Datalist_ID by DataList1?

javascript :
replace : this.disabled
by : document("<%= Button1.ClientID %>").disabled

jQuery :
replace : $(this)
by : $("#<%= Button1.ClientID %>")

Not working. may something wrong what I tried.

<asp:DataList ID="DataList1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="Horizontal">

 <asp:DropDownList ID="ddlMat" runat="server" name="ddlMat">

    <script>
window.onload = function() {
    var selects = document.getElementById("<%= DataList1.ClientID %>").getElementsByTagName("ddlMat");
     for(var i=0;i<selects.length;i++) {
            selects[i].onchange = function() {
                document("<%= Button1.ClientID %>").disabled;
            }
     }
}
</script>

Just add this to your current document.ready block :
      $("#<%= ddlMat.ClientID %>").change(function() {
            $("#<%= btnQuote.ClientID %>").attr("disabled", true);
       })

It working in the link but the script displayed there is different.

        $(document).ready(function () {
            $(".txtQty").keyup(function () {
                $("#btnQuote").attr('disabled', 'disabled');
            });
            
      $("select", "#DataList1").change(function() {
            $("#btnQuote").attr("disabled", true);
       })

        });
