Developing a Multi-Select ASP.NET GridView using JQuery


GridView is a very common control used in all .net Web Application. Also selecting a single row or multiple rows is a very common task in GridView operation. Most of the cases we do the Server Side Selection which is very pain-full. It's still more pain-full if we have a functionality for multi-select.


(Fig-1: Multi Select Gridview using Checkbox)

In some cases we add a Checkbox Control to get the selected rows at server side (see the above sample). But we always try for a Client Side row selection and Server Side row Manipulation.

Mult-Select using JQuery

Here, I used the power of JQuery Selector functionality to do the Client Side row Selection and a server side row Manipulation. Hope this will help you a lot in your GridView operation.

Step by step to implement Multiselect by using JQuery.

Step 1:

Download and add JQuery source file to your project. The download is available at

Add the JQuery reference to the Webpage.

<script src="jquery-1.4.3.js" type="text/javascript"></script>

Step 2:

Add an HiddenField to any of the TemplateField inside the GridView <Column> tag, which will store the selection mode (Here HiddenField will do the same operation like the CheckBox checked status).

Here I have added HiddenField along with the Id Column.

 <asp:TemplateField HeaderText="Id#" HeaderStyle-Width="50px">
<asp:Label ID="lblId" runat="server" Text='<%# Eval("Id") %>'></asp:Label>
<asp:HiddenField ID="hdnIsItemSelected" runat="server" />

Step: 3

Within JavaScript block add the following code. This the main part where selection of the row is being handled.

<script type="text/javascript">
$(document).ready(function () {

$(function () {
$('#MultiSelectGrid tr').mouseover(function () {
$('#MultiSelectGrid tr').removeClass('RowHover');

$(function () {
$('#MultiSelectGrid tr td').click(function () {
if ($(this).parent()[0].className == 'RowHover') {
.rowIndex - 1].value = 'true';
else {
.rowIndex - 1].value = 'false';

Step: 4

Add the following CSS to your StyleSheet or inside the <style></style> of <head> tag. These CSS classes will control the mouse hover and selection effect of the Gridview.

color: #336699;
cursor: pointer;
background-image: url('images/selected_item_back.png');
background-repeat: repeat-x;

color: #336699;
cursor: pointer;
background-image: url('images/hover_item_back.png');
background-repeat: repeat-x;

Step: 5

Now in the button click event or in the postback event, search each HiddenField status, if it's "true" it's selected else not selected.

foreach (GridViewRow row in MultiSelectGrid.Rows)
HiddenField selectionButton = (HiddenField)row.FindControl("hdnIsItemSelected");
if (selectionButton.Value == "true")
// do your operation here...

selectedName += (selectedName == "" ? "" : " / ") + ((Label)row.FindControl


Step: 6

Now run the application and see the impact of JQuery while selecting the row. In the given sample application I have added the DataSource for GridView in the Page_Load() Event.

Below two sample screens for Multi-Row Select and Single-Row Select of a Gridview.

Download the sample code and open it in VS-2010 and see how easy to understand the implementation.
