Question

I would like to show a confirmation Box with the message when the user check the CheckBox.

So i have a GridView and there is a column for CheckBoxes.
So whenever user check the CheckBox i would like to show a confirmation box and when user click cancel on that box i would like to uncheck that CheckBox.
when user press OK then i would like to fire a standard asp.net CheckBox_CheckedChanged where i am doing some database work.
I dont know how to do that in javascript or Jquery.
I found it on google where there is only one CheckBox and you can use the ID and using the Jquery you can show the popup.
BUT i have a GridView and there are lots of CheckBoxes for each row.

Please suggest me some working example or Code.

Thanks

***** EDITS *******
here is the code i have got so far.

$('#gvOrders').click(function () {
        var checked = $(this).is(':checked');
        if (checked) {
            document.getElementById("confirm_value").value = "Yes";
            if (!confirm('Are you sure you want to mark this order as received?')) {
                $(this).removeAttr('checked');
            }
        }
        else {
            document.getElementById("confirm_value").value = "No";
            if (!confirm('Are you sure you want to mark this order as  not received?')) {
                $(this).removeAttr('checked');
        }
    });

This is not working so far when CheckBox checked. I am not sure what i am doing wrong here.

Using jQuery

Assign some class to your gridview checkbox and bind the event on that class.

<asp:CheckBox id="chkChoice" runat="server" class="some-class" ></asp:CheckBox>    

$('.some-class').click(function () {
    var checked = $(this).is(':checked');
    if (checked) {
        document.getElementById("confirm_value").value = "Yes";
        if (!confirm('Are you sure you want to mark this order as received?')) {
            $(this).removeAttr('checked');
        }
    }
    else {
        document.getElementById("confirm_value").value = "No";
        if (!confirm('Are you sure you want to mark this order as  not received?')) {
            $(this).removeAttr('checked');

        }
    }
    //return someVariableHoldTrueOrFalseForPostBack
    //return true of false from here.
});

Using javascript

You can bind the javascript event on check box and it will be applied to all generated checkboxes of each row of grid automatically.

<asp:CheckBox id="chkChoice" runat="server" OnClientClick="return yourFunction(this)" ></asp:CheckBox>

function yourFunction(source)
{
     return confirm("your message"); 
}
