Part 66 - Check uncheck all checkboxes with another single checkbox using jquery

Suggested Videos 
Part 63 - Implement paging
Part 64 - Implement sorting
Part 65 - Deleting multiple rows

In this video, we will discuss, how to check/uncheck all checkboxes with another single checkbox using jquery in an mvc application. Please watch Part 65, before proceeding.

We want the output as shown below
Check uncheck all checkboxes using jquery

Here is the requirement
1. When the checkbox in the header is selected, all the checkboxes in the respective rows should be selected. If we deselect any of the checkbox, then the header checkbox should be automatically deselected.
2. When the checkbox in the header is deselected, all the checkboxes in the respective rows should be deselected as well. If we start to select each checkbox in the datarows, and upon selecting checkboxes in all the datarows, the checkbox in the header should be selected.
3. We also need a client side confirmation, on the number of rows to be deleted. The selected rows should be deleted from the database table, only when OK button is clicked. If cancel button is clicked, the form should not be posted to the server, and no rows should be deleted.

Here's the required jQuery script. Please paste this in the "Index.cshtml" view.
<script src="~/Scripts/jquery-1.7.1.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">
    $(function () {
        $("#checkAll").click(function () {
            $("input[name='employeeIdsToDelete']").attr("checked", this.checked);

            $("input[name='employeeIdsToDelete']").click(function () {
                if ($("input[name='employeeIdsToDelete']").length == $("input[name='employeeIdsToDelete']:checked").length) {
                    $("#checkAll").attr("checked", "checked");
                else {

        $("#btnSubmit").click(function () {
            var count = $("input[name='employeeIdsToDelete']:checked").length;
            if (count == 0) {
                alert("No rows selected to delete");
                return false;
            else {
                return confirm(count + " row(s) will be deleted");

  6. Hey - you started working with Paging then dropped Paging to add checkboxes to select multiple records. Can you do this again but do it with Paging?

    [input type="submit" id="btnSubmit" value="Delete selected employees" /]
