I have used the following script to check whether an item is selected from grid view or not which works fine. When I am showing a confirm box and if the user selects OK I am returning to true if not False. But on Ok I am unable to delete the selected item from the grid view can any one help.

C#

<script type="text/javascript">
    $(document).ready(function () {
        $("#ContentPlaceHolder1_btnDelete").click(function () {
            var gv = document.getElementById("<%=grdPayroll.ClientID%>");
            var rbs = gv.getElementsByTagName("input");
            var flag = 0;
            for (var i = 0; i < rbs.length; i++) {
                if (rbs[i].type == "checkbox") {
                    if (rbs[i].checked) {
                        flag = 1;
                        break;
                    }
                }
            }
            if (flag == 0) {
                jAlert('Select One', 'Alert Dialog');
            }
            else {
                $("#ContentPlaceHolder1_btnDelete").click(function () {
                    var gv = document.getElementById("<%=grdPayroll.ClientID%>");
                    var rbs = gv.getElementsByTagName("input");
                    var flag = 0;
                    for (var i = 0; i < rbs.length; i++) {
                        if (rbs[i].type == "checkbox") {
                            if (rbs[i].checked) {
                                flag = 1;
                                break;

                        //return false;
                    }
                    else {

                            if (r == true)
                                return true;

Do you want to delete items from the gridview, or from the table that is on the client side ? You're checking if the boxes are checked twice, could it change ? You need to add code to remove the items, there's tons of tutorials on the web on how to do that. Here[^] is just one example.

I need to delete from database and update the grid. I have written the code for that but from the script I am not getting return value as true.

You can use Chrome to step through your js and debug it. Your code just returns true or false, I don't see any line that does an AJAX call to delete the data.
