JQuery Check for Checkbox is checked

Question

The function always returns false, eventhough the checkbox is checked. I really couldn't crack down what i'm doing wrong. I'm using a checkbox to enable and disable the textbox in the gridview. However, it doesn't seem to work. Thanks for the help. I have posted the html and jq code below.

HTML code:

<asp:GridView ID="grdFees" runat="server" AllowPaging="false" CssClass="Grid" AutoGenerateColumns="false" EmptyDataText="No Data Found" EmptyDataRowStyle-HorizontalAlign="Center" EmptyDataRowStyle-CssClass="gridItem" TabIndex="5">
<Columns>
<asp:TemplateField HeaderText="Select" HeaderStyle-HorizontalAlign="center"
                                ItemStyle-HorizontalAlign="center" ItemStyle-Width="2%">
                                <ItemTemplate>
                                    <asp:CheckBox ID="chkselect" runat="server" CssClass="checkbox" 
                                    Width="15px" Checked="false" />
                                </ItemTemplate>
                            </asp:TemplateField>

</Columns>
</asp:GridView>

Jquery code:

$(document).ready(function() 
    {
        $(".checkbox").click(function()
        {
        if ($(this).is(":checked")) 
        {
            alert("true");
        }else
        {
            alert("false");
        }
});

ASP.NET probably doesn't apply the value of CssClass to the check box itself, but to the generated label and/or container element.

Try using the :checkbox selector instead:

$(document).ready(function() {
    $("input:checkbox").click(function() {
        if ($(this).is(":checked")) {
            alert("true");
        } else {
            alert("false");
        }
    });
});
