I am trying to get access and find text-box in GridView using javascript but i am getting an error: 'The name txt_UID' does not exist in the current context'. Everything worked fine when my text-box was outside of the GridView. Here is my text-box in the gridview and my gridview is called GridView1:


 <asp:TemplateField ItemStyle-Width="150px" HeaderText="User Assigned">


     <asp:TextBox ID="txt_UID" runat="server" Text='<%# Eval("UID")%>'

        CssClass="AutoCompleteTextBox" Width="130px" BackColor="LightGoldenrodYellow"></asp:TextBox>


         <ItemStyle Width="150px" />


Here is my JavaScript:


  <script type ="text/javascript">

        function setAutoComplete() {

            var textBoxes = document.getElementsByClassName("AutoCompleteTextBox");

            for (var i = 0; i < textBoxes.length; i++) {






<script type="text/javascript">

    function addAutoComplete(textBoxId) {

        $("#" + textBoxId).autocomplete({

            source: function (request, response) {


                    url: '<%=ResolveUrl("~/Service.asmx/GetUserNames") %>',

                    data: "{ 'prefix': '" + request.term + "'}",

                    dataType: "json",

                    type: "POST",

                    contentType: "application/json; charset=utf-8",

                    success: function (data) {

                        response($.map(data.d, function (item) {

                            return {

                                label: item.split('-')[0],

                                val: item.split('-')[1]




                    error: function (response) {



                    failure: function (response) {





            select: function (e, i) {

                $("#<%=hfUserId.ClientID %>").val(i.item.val);


            minLength: 1



<script type ="text/javascript">

     $(document).ready(function () { setAutoComplete(); });

Your Gridview will be rendered as Table and your control will be contained in cell of table. You can give a try to following.


<script type=”text/javascript”>


tblTable=document.getElementById(‘<<Client ID of the GridView>>’);

Cell=tblTable.rows[i].cells[j];//i and j are locations of that cell.

FirstControl = Cell.childNodes[0];



replace <<Client ID of the GridView>> with id of your GridView

you can use name attribute and the grid id to find it:


<asp:TextBox ID="txt_UID" name="mytextbox" runat="server" Text='<%# Eval("UID")%>'

        Width="130px" BackColor="LightGoldenrodYellow"></asp:TextBox>

the javascript part:


$("#<%=MyGrid.ClientID %>[name=mytextbox]").autocomplete({});
