How to show Id of Dynamically created Checkbox on Checkbox checked Using JQuery in ASP.Net

Hi rhino000,

Refer below code you can assign the checkbox id like below but you can access the id at client side.

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            for (int i = 0; i < e.Row.Cells.Count; i++)
            {
                CheckBox checkBox = new CheckBox();
                string val = e.Row.Cells[i].Text;
                checkBox.Text = val.ToString();
                checkBox.ID = "chk" + Convert.ToInt32(i).ToString();
                checkBox.Attributes.Add("class", "dynamicCheckbox");
                e.Row.Cells[i].Controls.Add(checkBox);
            }
        }
    }
}

Jquery

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script type="text/javascript">
        $(function () {
            $('.dynamicCheckbox').click(function () {
                $(this).closest('tr').find('[id*=chk]').each(function () {
                    if ($(this).is(':checked')) {
                        alert($(this).attr('id').split('_')[$(this).attr('id').split('_').length - 1]);
                    }
                    else {
                        $(this).attr('checked', false);
                    }
                });
            });
        }); 
    </script>
